Cost & Benefit Analysis and Toolkits

Introduction and Executive Summary The objective of ISGAN’s Annex 3 is to develop a global framework and related analyses that can identify, define, and quantify in a standardized way the...

Introduction and Executive Summary

To meet the required objective of this Annex, a program of work is designed and it includes the following three tasks:

  • Task 1: Assess Current Network Maturity Model and Update data
  • Subtask 1.1: Trial application of two network maturity analysis tools and results discussion
  • Subtask 1.2: Development of the questionnaire for the assessment of the level of smartness of transmission and distribution networks
  • Task 2: Analyze Current Benefit-Cost Analytical Methodologies and Tools
    • Subtask 2.1: Analyzing benchmark benefit-cost frameworks and tools
    • Subtask 2.2: Model research to overcome limit of current BCA frameworks and tools
  • Task 3: Develop Toolkits to Evaluate Benefit-Costs
    • Subtask 3.1: Development of Simplified cost-benefits analysis tool
    • Subtask 3.2: Technical Analysis of current BCA took-kit and Modification of Simplified tool-kit

For Task I, the report goes through several maturity frameworks available, especially those of Software Engineering Institute (SEI) and Katholieke Universiteit Leuven (KUL). The SEI has developed a management tool that can be used to measure the current state of a smart grid project, aiming to help utilities to identify the target and build proper strategies to reach it. The tool, Smart Grid Maturity
Model (SGMM), utilizes a set of surveys called Smart Grid Compass. The drawback of this tool is the undocumented scoring method of the surveys once a result is obtained. Full assistance of an SGMM Navigator is required for the utility to understand and analyze the SGMM output. Meanwhile, the KUL introduce the characteristics, categories and key performance indicators of a smart electricity grid. The previous report also includes own survey methods developed by Annex III, although there has not much of progress after that.

For Task II, an extensive update of the BCA survey has been provided in the previous report. It started with various frameworks related to BCA, which include Frontier Economics and the Smart Grid Forum (SGF) in UK, Smart Grid Investment Model (SGIM) of SGRC, I
MPLAN Model, McKinsey Tool, and general overviews of EPRI’s methodology to BCA and its subsequent developments by DOE and JRC. After that, several BCA applications to country-specific or states cases are summarized. Some of the surveyed countries are Czech Republic, Netherland, Lithuania, Denmark, and USA states. For the comparison purpose, the summary for each case is carried out following some key points: background of the smart grid project, the methodology or toolkits used, the scope of the project (location, period, technologies), the list and definition of benefits and costs, and deliverables (results, recommendations, policy andregulations). The 1st year’s work of Task II can be compared with the previous year’s work in the sense that how EPRI guideline has any impact on the work development of JRC and DOE frameworks, especially for the Smart Grid Computational Tool (SGCT), a BCA toolkit that is developed by US DOE. This report summarizes the findings from the previous works with the focus of selecting the benchmark smart grid tool kit for the development of own ISGAN tool kit for member countries.

For Task III, a simplified cost-benefit analysis tool is being developed taking SGCT of DOE as a benchmark tool kit, based on the previous year report on the development plan of ISGAN member countries’ toolkit. A standalone program based on Object Oriented Programming (OOP) is now being developed replicating, revising and upgrading the currently available excel-based SGCT. As will be discussed, this tool kit has various advantages over other tools: First, this tool is open to public and anyone can take a look inside of the model deep enough to examine the visual basic application modules. JRCEU, McKinsey models were once discussed in Annex III before for any potential utilization for ISGAN member countries’ tool kit. However, members acknowledge the fact that JRC works on excel based format and there seems to be not much difference between JRC’s work and DOE. The difference lies in the fact that JRC never opened up the details of the functionalities and sample calculation of BC in their whole work process. McKinsey software was discussed but it is not open to public. Rather it is a commercial package with no specific advantage over to SGCT of DOE. Detailed engine is not fully explained and the scope of the analysis the tool kit provides does not seem to be very useful (Nigris 2012, Kim 2013). The new tool kit being developed is named for the time being as ‘Replicated Tool Kit’ for convenience. Through the replication process, a lot of details have been identified, which, otherwise, would not have been known to us. Many of the parameters utilized in the process of benefitcalculation may be required to be collected from outside, reflecting the region specific characteristics. Some of the default values provided by SGCT, although they are from USA case (refer to Appendix), may also be useful until those detailed information becomes available for ISGAN member countries even when they don’t have them.

In addition, there a at least 12 smart grid projects currently being conducted in USA (refer to III.2.24), and those projects are starting to produce some detailed information which might be potentially utilized by current SGCT. Not only those advantages, there are many interesting researches being conducted around the world and the work results could be very useful sources of updating this replication effort in the future, once this replication process allows us to identify the pros and cons of the current model. The last chapter of the Expansion of Smart Grid Computational Tool is the wild idea of what could be accomplished in this whole process of simplified own ISGAN tool kit for member countries. Some of the ideas for the tool kit development become clearer as the process of the replication progresses. By the time of the completion of this year’s work, we hope to have a very concrete idea on how to proceed to further develop this current work in the future for the benefit of every member country in ISGAN.

Policy Insights

Annex 4: Synthesis of Insights for Decision Makers Organization of knowledge, key issues, important themes, insightful analysis for the benefit of decision makers....

Synthesis for Decision Makers

 

Given the wide variety of definitions and conceptual models for smart grid technologies and systems, quickly increasing body of literature and analysis, and rapid rate of change in the smart grid space, senior decision makers and their staff would likely benefit from a common basis or language for discussion. To this end, this Annex integrates the knowledge and lessons learned through the other ISGAN Annexes. This material may be delivered through a variety of media, such as reports, web sites, or videos, as appropriate for the specific information and targeted audience. It may be structured for specific geographies or grid ecosystems. Ultimately, information packages that explain clearly and concisely smart grid benefits and costs (and offer an intuitive, pleasing user experience) will help capture the attention of these decision makers and provide them the information needed to advance more effective smart grid-enabling policies and programs.

 

Objectives

The core objectives of Annex 4: Synthesis of Insights for Decision Makers are to organize knowledge, identify key issues, distill important themes, and provide insightful analysis for the benefit of policymakers. It will highlight existing lessons learned and best practices on smart grid and seek to integrate and package knowledge in a form that will be useful and used by the target audience. Moreover, this Annex will consolidate and disseminate the efforts of other ISGAN Annexes, as well as smart grid efforts beyond ISGAN when appropriate, in support of greater reach and impact.

 

Current Activities

For the 2018-2019 timeframe, we are focusing on the following activities:

  • Deep-dive, peer-to-peer workshops on exchanging best practices on smart grid deployment enabled via policies, regulations, programs, and public-private partnerships
  • Development of and building capacity to implement a corporate ISGAN Communications Strategy
  • Additional work on policy insights and analysis delivered through synthesis papers and webinars
  • Support for intecannex coordination and collaboration

 

Past Work

Highlights of past work include:

  • Policy insight reports and webinars on the role of smart grids in integrating renewable and variable energy, smart grid cyber security, smart grid technology as an enabler of clean energy, and managing consumer benefits and costs
  • Implementation of in-depth knowledge transfer workshops in Mexico and India to inform national smart grid strategies

Spotlight on Smart and Strong Electric Power Infrastructure Best practice shared from the ISGAN Annex 6 case book

The introduction in the generation mix of a continuously increasing share of generation from renewable energy sources (RES), the geographical spread of generation when increasing the amount of distributed production, as well as changing patterns of demand from new types of load such as electric vehicles, will create new challenges for the electric power transmission and distribution (T&D) systems.

The case book Spotlight on Smart and Strong Power T&D Infrastructure spotlights a number of projects sharing best practices to meet challenges for the power systems to become stronger and smarter.

Many different approaches are possible to meet these challenges and the regulators have a key role in supporting the development towards clean sustainable solutions.
Different countries have different challenges, will use different solutions to those challenges, and have reached different maturity in the implementation of those solutions. Smart grid solutions are also found across the entire electrical system, from the high voltage transmission grid, through the distribution grid and finally on consumer level. It is therefore no generic solution or size that fits all for the solution towards the smart and strong grid. At the same time there are generic solutions and findings from experiences that can be adapted by other countries to make local implementation faster and more efficient.

Why We Do Not Know Much about the Social Dimension of Smart Grids Transition?

Dealing with smart grids transitions, three years of activity of Annex 7 make it evident that policy makers are having many important questions about the dynamics of institutional change which...

However, rather than being able to provide ready-made answers about the institutional and social dimensions of smart grids, much more can be said about what-we-don’t-know. We identified two main reasons why we do not know enough about smart grid transition.

  1. The structural challenge is that energy research is mainly focusing on technologies for the physical grid with little knowledge on institutional change and the social dimension of energy transition.
    In an article in Nature, B.K. Sovacool (Vol 511, 2014) examined the scope of more than 4400 articles in leading energy technology and energy policy journals over 15 years. He identified four trends which he evaluates as worrisome if not tackled by public and private organizations and the scientific community:
    a. An underevaluation of influence of social dimensions on energy use,
    b. A bias towards science, engineering and economics over other social sciences and humanities,
    c. A lack of interdisciplinary collaboration and
    d. The underrepresentation of female authors or those of minority groups
    This corresponds to the challenges identified in developing a strategic research agenda for Smart Grids Transitions of Annex 7. The European Commission in its Horizon 2020 research and innovation program tries to address this issue by encouraging SSH research to be taken up in energy research projects. An interim evaluation2 shows the low level of SSH research with the main part going to economic research. Other disciplines are hardly visible and there is a significant geographical divide between countries in taking up the possibility to integrate SSH research.
    There is the need to insert the social and environmental dimensions in the projects of smart grid deployment as well as in the decision making processes needed to select the most appropriate solutions. It is not enough that projects be perfect from the technical and economics point of view, they should be based on a sound social analysis and include specific actions to take into consideration the concerns, needs, and expectations of citizens and consumers.
  2. Although the political will to further increase the public energy-R&D investment in the CEM countries substantially exists, statistical evidence shows a stagnation of energy related social-science-humanities R&D investment at a very low level.
    R&D statistics (OECD/IEA, EU – Horizon 2020) indicate that increases in public R&D spending over the last years did not lead to a more balanced resource-attribution for all research disciplines. Particularly, research resources for social sciences and humanities (SSH) have not yet received the attention it would require to learn more about embedding technological development in the economic and societal environment (e.g. on energy use, or on how future markets will look like).3
    Although the obstacles of data accuracy exacerbate the analysis, still two statements can be made:
    a. The share of R&D from SSH in the area of energy4 in OECD countries has been fluctuating significantly over the last years. When adding up all reported country figures between 0.1% and 9% during the period of 1974 and 20155.
    b. If at all, SSH-research capacities and funding in absolute terms is growing with much less speed than in engineering and natural sciences.
    Given the high uncertainties, how global energy transition should take place and the lack of orientation where technological development should lead to, SSH research will be needed even more urgently than in times of relative stability of the energy system.
    The intention of Mission Innovation, to double public clean-energy R&D investment over five years, is an encouraging signal for R&D actors and will likely lead to structural changes in the research and innovation-eco-system. However it remains to be seen, if this could also lead to a substantial rise in the knowledge about the social dimension of smart grids, without a political will to provide significant resources for SSH research as well as the appropriate R&D instruments.
    The following conclusion and recommendations can be drawn from this analysis:
  • Significantly more inter- and transdisciplinary research activities in social sciences and humanities are needed.
  • More attention has to be laid on generating know-how on social dimensions of technological and institutional transformation of energy systems and markets.
  • Financial resources for SSH research need to be raised at least as much as for technological development and the respective R&D capacities and infrastructures need to be built up sustainably. Collaboration and strategic research agendas should be coordinated amongst CEM-countries.
  • There is an urgent need for more accurate statistical data on SSH in energy research.

Case Studies

Smart Grid Case Studies and In-Depth Knowledge Sharing National Drivers for Smart Grids and best practices for implementation.

Smart Grid Case Studies

Currently, Annex 2 has two priority workstreams, the first of which is an assessment of current case studies on smart grid deployments. This includes creation of a common methodological framework for future case studies based on this assessment, and development of in-depth case studies using this framework. Capturing and communicating the lessons learned from real-life demonstration or deployment projects will help stakeholders understand the true promise and challenges of deploying smarter electricity grids. Such case studies will provide another layer of depth to the information available in the Global Smart Grid Inventory and provide data and metrics to inform development of benefit-cost analyses and decision-making tools under that Annex. Published case books are as follows. (click to see)

       

 

A second key work stream is enabling in-depth peer-to-peer knowledge sharing. More information on the Knowledge Transfer Project can be found here.

Inventory

Global Smart Grid Inventory Identify gaps, opportunities, synergies among smart grid activities and programmes. Catalogue the wide range of smart grid activities underway, mapping the actual activities against the drivers and interests.

Global Smart Grid Inventory (Completed)

Many participating ISGAN countries are already developing, demonstrating, testing, and deploying smart grid technologies and systems, drafting policies and implementing regulations to advance smart grids, assessing current and projected transmission and delivery infrastructure needs, evaluating demand-side practices, and measuring other aspects of smart grids. In addition, many bilateral and regional cooperative efforts have been launched featuring smart grid as a significant or principal focus. The objective of this activity is to identify countries’ specific motivating drivers for pursuing smart grids, catalogue the wide range of smart grid activities underway, and collect and organize the wealth of experience being generated into a resource available first to ISGAN Participants and then a global audience. The ENARD Implementing Agreement has already started similar inventory work, through its Annex V, recently launched. Thus, close coordination will be sought with that and other relevant inventory efforts. It is expected that all signatories will contribute data and information to this Annex.

Smarter & Stronger Power Transmission: Review of feasible technologies for enhanced capacity and flexibility

Transmission and distribution (T&D) systems are facing new challenges linked with the introduction in the generation mix of a progressively increasing share of unpredictable energy sources and variable generation from renewable energy sources (RES).

Changing patterns of demand that new types of load such as electric vehicles (EV) will introduce large and unpredictable fluctuations in the power balance as well as variations in voltage can jeopardize the quality and availability of power. The T&D system has to be stronger and smarter to provide the real-time flexibility needed to efficiently handle the new conditions. Investment needs in the power T&D infrastructure are large and require long term planning and deployment. The environmental concerns and public acceptance issues that often arise when constructing additional conventional transmission lines will require more efficient solutions with lower environmental impact.

This Discussion Paper from ISGAN Annex 6 Power Transmission & Distribution Systems Task 3 and 4 focuses on “Smarter & Stronger Power Transmission” and is a review of feasible technologies for enhanced transmission capacity and flexibility in terms of status and deployment. This includes both the primary AC and DC technology for the high voltage transmission grid as well as the information and communication technology (ICT) required to efficiently supervise and operate the power system. Focus is on the development of power electronics including flexible AC transmission (FACTS) and high voltage DC (HVDC), the standardization within ICT such as IEC 61850 and Common Information Model (CIM) in order to obtain vendor independent interoperability as well as the progress of wide area monitoring, protection and control (WAMPAC). The combination of smarter ICT applications together with power electronics such as FACTS and HVDC can be described as a digitalization of the power system operation offering the required flexibility. Most of the examples given are from the Nordic European power system, reflecting the participation of the authors from ISGAN Annex 6 Task 3 and 4, with additional input from North America and selected International case studies.

Why the TSO-DSO Relationship Needs to Evolve

A number of emerging trends indicate that the interaction between transmission system operators (TSO) and distribution network operators (DSO) will evolve in the coming years.

Examples of these trends are the electrification of energy consumption and the increasing volume of distributed generation being connected to the distribution grid.

The relationship between transmission system operators (TSO) and distribution network operators (DSO) is changing. Examples of these trends are the electrification of energy consumption and the increasing volume of distributed generation being connected to the distribution grid. In Europe this subject is highly relevant as pointed out by ENSTO-E (European Network of Transmission System Operators for Electricity) in their paper, Towards smarter grids: Developing TSO and DSO roles and interactions for the benefit of consumers published in March 2015, and ACER (Agency for the Cooperation of Energy Regulators) in their conclusions paper, Energy Regulation: A Bridge to 2025 published in September 2014. ENTSO-E is an association which represents 41 European TSOs and has an objective to promote closer cooperation across Europe’s TSOs to support the implementation of EU energy policy objectives of affordability, sustainability and security of supply. ACER is an agency of the European Union with the overall mission to complement and coordinate the work of national energy regulators at EU level, and to work towards the completion of the single EU energy market for electricity and natural gas. The expected increased interaction between TSOs and DSOs will result in both technical and non-technical challenges.

IEA ISGAN Annex 6 has published a discussion paper in which the current and future cooperation between TSOs and DSOs has been investigated. Six critical grid operation challenges have been identified:
1. Congestion of the transmission-distribution interface
2. Congestion of transmission lines and distribution lines
3. Voltage support (TSO↔DSO)
4. Balancing challenge
5. (Anti-)Islanding, re-synchronization, and black-start
6. Coordinated protection

For each case, country experts provided first-hand information about the status and expected development of TSO-DSO interaction in their respective countries. This resulted in an overview, by country, of the interaction between grid operators and provided input for the discussion about how this interaction could evolve in years to come. Technical aspects, as well as policy aspects, have been taken into account.
The technical solutions required for a closer interaction between TSOs and DSOs are very similar for most of the identified cases, except for the case of islanding & black-start. From a high level viewpoint, grid monitoring has to be implemented, communication between TSO and DSO has to be established and means of communication between the DSO and its flexible customers have to be available. DSOs should also be able to perform (quasi) real time network simulations with input from measurements on the grid.
Such technical requirements should not be underestimated regarding implementation and operational cost, complexity and skills required. These could be a challenge, especially for smaller distribution network operators. Nonetheless, only the distribution grid operator has information about the actual grid configuration and grid loading. This means that even when other entities take up certain roles, for example the role of aggregator, the distribution network operator will always be responsible for monitoring the grid and will need to implement communication solutions to one entity or another.
With the current status of technology, technical requirements for an evolved interaction between TSOs and DSOs can be met. However, several non-technical issues, or points of discussion, have been identified which are closely related to the regulated environment grid operators are working in.

• Maintaining a balance between infrastructure investments and use of flexibility

Flexible demand and generation can be used to support grid operation and avoid infrastructure investments. A minimum use of flexibility will be necessary to avoid over investing, but the impact on the processes and business cases of flexible customers has to be limited. The flexibility available by curtailing renewable energy sources needs to be limited to avoid a high loss of renewable energy.

• The role of markets
Which grid operation challenges should be met by introducing markets and which should be managed only by technical means and appropriate bilateral contracts? It is proposed to use market mechanisms only for the balancing challenge, which is applied today in various countries. Coping with local grid operation challenges such as critical transformer loading, line loading and voltages, is proposed to be managed by the network operators, optimally interacting with each other and using flexible customers when necessary. Because of the local nature of the mentioned grid operation challenges, markets would not work efficiently. Instead, a regulatory framework is required for bilateral contracts between flexible customers and network operators, facilitating the use of flexible generation and demand for grid operation purposes.

 

• Setting a level playing field for flexibility
When the combined flexibility of customers on the distribution and transmission grid is used, favoring one set of customers at the cost of the other should be avoided. For example, when facing critical line loading on the transmission grid, the use of flexibility of only distribution connected customers would be undesirable. Some mechanism, probably in discussion with the regulator, should be implemented to cope with this.

• The role of regulation
Closely related to the previous statement is the discussion point on how grid operation should evolve:
more regulated, with clearer and stricter roles, or more open, with guaranteed interaction between grid operators and new market players? There is no one size fits all solution but in any case, a clear definition of the roles and responsibilities of all participants in future grid operation will be necessary and will serve as a good start.
A clear policy framework will, in every case, push forward investments in Smart Grid solutions to deal with the discussed challenges that grid operators are facing.
The article is based on a discussion paper published by IEA ISGAN Annex 6.

Spotlight on customer engagement and empowerment

The Case Book includes 10 cases on Consumer Engagement & Empowerment of the top 10 winning projects from the 1st ISGAN Awards Competition. Countries that are included in the CaseBook are Belgium, Denmark, France, Japan, Portugal, Netherlands, and USA.  

The objective of Annex 2 is to assess outstanding examples of current case studies, develop and validate a common case study template and methodological framework, and then develop in – depth case studies using this framework. The template is currently the “Case Book” to contain
descriptive information. The common frame work for case studies will allow comparison and contrast of policies and technologies adopted in different regulatory, legislative, network (grid), and natural environments. The overarching aim is to collect enough information from case studies around the world to extract lessons learned and best practices as well as foster future collaboration among participating countries. The Consumer Engagement Case Book reflects one way that ISGAN brings together experts and stakeholders from around the world to increase the awareness of consumer engagement in the field of smart grid.

Customer engagement and empowerment offers opportunities to save energy for customers and to operate the grid in a more efficient and reliable way for grid operators. Grid operators want to shift or reduce energy consumptions during times of peak consumptions, so they have  engaged and empowered customers to do that by proposing some benefits.
Cases of customer engagement and empowerment in this book share lessons learned in developing and deploying these technologies to  stakeholders.

The role and interaction of microgrids and centralized grids in developing modern power systems

An extension of microgrids is now underway, primarily to allow increased electrification in growing economies but also to meet the need to reduce global CO2 emissions and to provide ancillary services to centralized grids.

Energy access constitutes one of the fundamental building blocks for economic growth as well as social equity in the modern world. Access to sustainable energy is needed to achieve sustainable development. A microgrid should not be seen as a competitor to the centralized grid but as a complement.

Through examination of several implemented cases from different parts of the world the following topics are considered:

  • Analysis of the interaction between centralized grids and microgrids
  • Analysis of stakeholder decision parameters for electrification
  • Analysis of design differences and requirements for microgrids, depending on the intended purpose and the need of the end customers

It is determined that good planning, suitable requirements and clear regulations for microgrids (in relation to centralized grids) limits the risk of stranded assets and enables better business cases for the involved stakeholders.
The paper is based on the discussion paper The role and interaction of microgrids and centralized grids in developing modern power systems – A case review publiced by ISGAN (International Smart Grid Action Network) Annex 6: Power T&D Systems.
