micro vs MEGA grids

How do these trends in the development of the power systems influence each other?

Annex 6 has started an activity to study these trends which are largely influencing the decisions in the evolution process of the power grids.

In this work the trends are referred to as the micro grid and the mega grid trends, where the micro grid perspective focus on local solutions while the mega grid perspective focus on system or even intra-system wide solutions.

The objective of this work is to present a critical assessment of these trends, based on the questions:

  • Does one trend outcompete the other?
  • Does increased micro grid investments increase the need for mega grid investments, and vice versa?
  • To what extent can micro grids benefit from mega grid solutions, and vice versa?

The intention with this work is not to proclaim one solution being superior to another, instead it is intended to provide insights in the needs of considering both perspectives in the decision-making process for the sustainable development of the power grids.

The work involves parties from: Norway, Sweden, Germany, Belgium, Spain, Italy, France, Canada, South Africa, and India

Policy messages on Innovative Regulatory Approaches with Focus on Experimental Sandboxes to Enable Smart Grid Deployment

The urgency of transition of the energy system requires speeding up the innovation processes that will shape its future technological, economic and regulatory components.

As it is necessary to be quick, regulatory changes will often lag, what is identified as preferable pathways, but these changes could be accelerated through Regulatory Sandboxes, which are able to verify effects of new regulatory instruments before actual implementation.

All energy systems, whether vertically integrated or deregulated, have some sort of regulatory or market oversight. Some of these regulations have been long established and originate from stem out of initial structures created around the turn of the 20th century. However, as the electricity grid transitions towards a more decentralized structure, with deepened engagement of end-users (including consumers) and involvement of a wider variety of other stakeholders and service providers, there is a need to enable testing of new regulatory structures that can better support integration of advanced smart grid technologies and business models.

Casebook on Innovative Regulatory Approaches with Focus on Experimental Sandboxes

The idea for the focus of this casebook on experimental (regulatory) sandbox Initiatives was generated during the CEM9/Nordic Clean Energy Week, as a result of the workshop Intelligent Market Design – Boosting Global Smart Grid Deployment (23 May 2018) and the following Annex and inter-annex meetings. In these discussions, market regulation was repeatedly identified as a key topic for further collaboration in research and innovation.

This casebook provides detailed information on planned or implemented Sandbox Programs for Australia, Austria, Germany, Italy and The Netherlands. An overview of the previously well documented program in the UK is provided as well.

Hawaii is included as an example of another form of regulatory experimentation. In this case, one US state is experimenting with a performance-based method for tariffs which, if successful, can be rolled out as a regulatory innovation to other US states or other countries. The main focus of the casebook however is laid on experimenting to achieve the above mentioned innovation goals by means of sandbox projects.

Flexibility In Future Power Systems

Power system flexibility: the ability to manage change

Solutions providing advances in flexibility are of utmost importance for the future power system.
However, flexibility is not a unified term and is lacking a commonly accepted definition. The flexibility term is used as an umbrella covering various needs and aspects in the power system which complicates the discussion on flexibility and craves for differentiation to enhance clarity.

ISGAN Annex 6 has dedicated an activity on flexibility with the intention to support an increased understanding of the flexibility concept, proposing categorisation of flexibility needs in the power system.

This activity resulted in several publications with contributions from parties in: Sweden, Austria, Canada, France, Germany, Italy, Norway, and Switzerland.



  • In the Discussion Paper (DOI: 10.13140/RG.2.2.22580.71047), the full report is provided from this activity, including description of the flexibility categories: Flexibility for Power, Flexibility for Energy, Flexibility for Transfer Capacity, and Flexibility for Voltage.



  • The Scientific paper: Flexibility to support the future power systems, based on the discussion paper, was published for the CIGRE Symposium in Aalborg, Denmark, June 2019.


  • A poster including intermediate results were presented at the 8th International Conference on Integration of Renewable and Distributed Energy Resources (IRED) in Vienna in October 2018.

ICT aspects of TSO-DSO interaction

Data exchange and ICT requirements along organizational interaction between TSO and DSO

The main objective of this report is to assess the future data exchange and ICT requirements concerning the interaction of distribution and transmission networks, by identifying key challenges that deserve attention.

This report is based on a questionnaire regarding the ICT aspects of TSO-DSO interaction. The questionnaire contained questions regarding technical aspects (e.g. technical connection points between TSO and DSO in the countries), regulatory aspects, flexibility markets, drivers and barriers for TSO-DSO interaction as well as experiences from projects and lessons learned. The questionnaire was sent to the Annex partners and nine responses were collected. In particular Belgium, Germany, Italy, Finland, Sweden, United States, China, India and Austria have sent comprehensive answers.

Due to the integration of renewable energy sources, the interaction between TSOs and DSOs gets more and more important to handle the high volatility of generation and unexpected load growth in power grids. Additionally, new market mechanisms and the connected flexibilities require a closer interaction between TSOs and DSOs.

Social costs and benefits of Smart Grid technologies

This Discussion Paper maps and reviews existing literature about costs and benefits of smart grid projects and identifies gaps in current guidance. The report also includes an analysis of how network regulation affects costs and benefits of smart grid technologies. The report allows selecting models/methods to be used by the Swedish Smart Grid Forum in order to assess different smart grid projects and applications. It also provides input for further work on the topic of decision making for smart grid technologies.

Smart grid technologies represent different ways to enhance the effectiveness of the power distribution and transmission system by making it possible to use existing power infrastructure more efficiently. Implementation of smart grid solutions could for instance, represent an alternative to investment in new power generation capacity or new power lines.
Many new smart grid technologies are available, but not yet deployed. In order to advance implementation, governments and other investors need decision support to evaluate investments in smart grid technologies.

Cost-benefit analysis (CBA) offers a systematic process for comparing the advantages and disadvantages of a smart grid initiative from society perspective.
This report presents a mapping and analysis of existing literature on social costs and benefits of smart grid solutions and identifies gaps in current guidance. The study also includes a review on how network regulation affects incentives to invest in smart grid technologies and an analysis on how CBA constitutes an important input to the design of the network regulation. The report also serves as a basis for selecting models and methods to be used by the Swedish Smart Grid Forum in order to assess different smart grid projects and applications.

Due to the multifaceted and broad nature of smart grid technologies, CBA of smart grid deployment is complex as smart grid technologies provide benefits on a system level as well as on the project level. Smart grid technologies are also under fast development, which lead to a lack of data and uncertainty when extrapolating results from pilot projects to the system level.

Energy and climate goals as those identified on the European level as well as on a national levels aim to increase renewable energy, improve energy efficiency and reduce carbon emissions. Smart grid technologies contribute to all these goals, not only directly but to large extent indirectly, which calls for comprehensive evaluation methodologies on a system level. Comprehensive analyses on the system level can provide input to CBA.
The aim of CBA is to identify all the gains and losses (benefits and costs) created by an initiative. The intention is to express the gains and losses in monetary terms irrespective to whom they accrue.

On a general level, CBA contains three mains steps. These are identification, quantification and valuation of the benefits and costs.
