Webinar: Flexibility needs in the future power system

This webinar introduces you to the flexibility needs in the future power system. Multiple angles are considered: stability, frequency, voltage, power quality and balance at different time scales (from seconds to hours and seasonal adequacy).

Wednesday, November 6, 2019 from 2:00 PM to 3:00 PM CET

Power system flexibility relates to the ability of the power system to manage changes.

Solutions providing advances in flexibility are of utmost importance for the future power system. Development and deployment of innovative technologies, communication and monitoring possibilities, as well as increased interaction and information exchange, are enablers to provide holistic flexibility solutions. Furthermore, development of new methods for market design and analysis, as well as methods and procedures related to system planning and operation, will be required to utilise available flexibility to provide most value to society.

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. This situation makes it highly complex to discuss flexibility in the power system and craves for differentiation to enhance clarity. In this work, the solution has been to differentiate

the flexibility term on needs, and to categorise flexibility needs in four categories.

Here, flexibility needs are considered from over-all system perspectives (stability, frequency and energy supply) and from more local perspectives (transfer capacities, voltage and power quality). With flexibility support considered for both operation and planning of the power system, it is required in a timescale from fractions of a second (e.g. stability and frequency support) to minutes and hours (e.g. thermal loadings and generation dispatch) to months and years (e.g. planning for seasonal adequacy and planning of new investments).

Summary of Public Workshop: “Needs, challenges and opportunities of TSO-DSO coordination”

The workshop attracted various stakeholders from both the research and industry community and facilitated various presentations and discussions centered around the current and anticipated future interaction between the TSO and DSO.

On the 03-10-2019 the Swiss Federal Office of Energy SFOE and Research Center for Energy Networks – ETH Zürich in cooperation with ISGAN Annex 6 (Power Transmission & Distribution Systems) hosted a public workshop on needs, challenges and opportunities of TSO-DSO coordination in Montreux, Switzerland.

An introduction to the workshop demonstrated how there has been a paradigm shift in the electrical supply industry, where the traditional characteristics of centralized generation, fixed loads, and uni-directional power flow have transformed into systems which are decentralized, controllable and incorporate bi- directional power flow. This shift toward distributed and renewable electricity poses as a challenge to both the TSO and DSO and thus there has been an increasing awareness relating to the needs, challenges and opportunities associated with the implementation of the necessary solutions. Successful TSO-DSO coordination requires the consideration of various perspectives of the technical, market and regulatory aspects in order to maximize the potential benefits provided by DERs, this includes congestion relief, reactive power and voltage control and frequency reserves.

An overview of International Activities on TSO-DSO interaction extending from 2014 to 2019 was provided. Since the results of various projects relating to TSO-DSO interaction are starting to become available, investigations are currently being conducted on the ‘Lessons learned on international projects on TSO-DSO interaction’ which will consolidate the outcomes of these projects and will be available in 2020. This deliverable will take the form of an interview style video, in which various stakeholders are invited to participate. A sneak preview of the video was shown at the workshop and received a positive response from the audience.

Additionally, some highlights of the workshops included a summary of TSO-DSO report which focused on the TSO-DSO interaction in congestion management and balancing. The drive for increased in TSO-DSO interaction was also emphasized in countries such as Ireland, where a target for 75% power generation from non-synchronous machines is to be achieved and raises the question as to ‘who’ is responsible for providing the necessary reactive power in order to achieve this goal. Further information into the development of business use cases which enable the TSO-DSO coordination was also presented. An interesting analogy between the power system and the human body showed that, it is necessary to ensure the optimal health of the power system which often requires a systematic behavioral change. In this regard, it has become evident that demand side management plays an important role in terms of market related aspects and that sufficient incentives for optimization should be introduced when it comes to DER flexibility.

The panel discussion incorporated a Q&A session received a constructive response. The presenters from the previous discussion were available for further questions and discussion.

Needs, challenges and opportunities of TSO-DSO coordination

There is a trend across the world, towards utilizing more distributed energy resources (DERs) and an increased involvement of "active consumers" in energy supply.

The transition from a system comprised primarily of dispatch-able generators to a system increasingly reliant on intermittent power sources increases the variability, uncertainty and thus also the need for flexibility.  DERs and “active customers” can provide more flexibility and thus more services to both Distribution System Operators (DSOs) and Transmission System Operators (TSOs).   This shift toward distributed and renewable electricity supply poses challenges to both the TSO and DSO; however, it also encourages exploitation of less utilized coordination synergies to achieve mutual benefits.

The coordination between TSOs and DSOs is of utmost importance for the grid to obtain the full value from services potentially provided by DERs such as, congestion relief, reactive power, voltage control and frequency reserves.

The public workshop will explore the needs, challenges and opportunities of TSO-DSO coordination from a broader perspective accounting for technical, market and regulatory aspects and different views from national/international TSOs, DSOs, and smart grids projects.


The participation is open to the public and free of charge, but a registration is necessary.  Please, register until Friday, 20 September 2019, at https://www.bfeevents.admin.ch/ …

Dynamic Line Rating: Principles – Applications – Benefits

The next webinar in the ISGAN Academy introduces you to the physics of Dynamic Line Rating (DLR). Learn how DLR data have been integrated into grid operators' processes, and how they can help to increase cross-border trading, reduce grid congestion, and support investment decisions.

Monday, July 29, 2019 from 2:00 PM to 3:00 PM CEST

The webinar will introduce the physics of Dynamic Line Rating (DLR), and calculation methods based on CIGRE and IEEE standards. Various approaches are discussed: direct measurement technologies (sensors) as well as (weather) model-based simulations. We describe applications implemented by grid operators for some years already. These illustrate how DLR data have been integrated into grid operators’ tools and processes, in particular how forecasts are used.


Furthermore, some analytics will be share that demonstrate the benefits of DLR for reducing OPEX and CAPEX. This includes examples on increasing cross-border trading, reducing investment on new line infrastructure and reducing congestions, which helps to make decisions on reinforcement and investment.

Webinar: Vehicle-to-Everything (V2X) Energy Services

Along with rapid EV uptake will come significant increase in electricity demand and electric power impact on the grid as public, private, and fast-charging infrastructure is developed. The ability to control and plan for the coming EV revolution will be crucial to ensuring the security of supply of global electric grids while weaning the transportation sector off of fossil fuels.

Additional trends of increasing penetration of distributed energy resources and energy storage acting in bi-directional operation paired with greater communication capabilities (i.e. the “Smart Grid”), will enable more intelligent charge control and greater integration of electric vehicles. The topic of this ISGAN webinar is on the coming Vehicle-to-Everything (V2X) paradigm and its impact on the developing smart grid. While PHEVs and hydrogen fuel cell electric vehicles will also play an important role, the focus of this webinar will be on fully battery electric vehicles due to the energy and power capacity requirements of V2X. We will cover three main areas of interest: the grid impacts of EV integration, an explanation of the V2X paradigm, and a review of regulatory issues associated with V2X.

V2X is an umbrella term to explain the use of Electric Vehicle (EV) batteries to provide energy services and derive additional value from the battery asset during times of non-use. V2X services aim to generate revenue from the battery asset through dynamic or bi-directional charge control to provide benefits to the electric grid or to reduce/flatten/shift peak energy consumption of buildings and can be classified in the following operating modes:

· Vehicle-to-Grid (V2G): Using an EV battery to interact with/provide value to the electric grid
· Vehicle-to Building (V2B): Operating EV batteries to optimize building energy consumption
· Vehicle-to-Home (V2H): Optimizing home energy consumption or as emergency back-up power
· Vehicle-to-Load (V2L): Any other instance of an EV battery providing energy to a load

Smart Grids & District Heating and Cooling: Key Integration Aspects

An international cooperation between IEA ISGAN Annex 6 “Power Transmission and Distribution Systems” and IEA DHC Annex TS3 „hybrid energy networks“ will meet for an interactive cooperation event: 1-2 April 2019, Stockholm, Sweden

Integrating the different energy domains and thus creating “hybrid energy networks” is considered to be one of the key aspects of the future energy system. The interdisciplinary cooperation between international experts from ISGAN and DHC Annex TS3 is a unique opportunity for developing innovative solutions and successful business models towards a sustainable and flexible energy infrastructure.

  • The IEA International Smart Grid Action Network (ISGAN) supports the accelerated development and deployment of smarter, cleaner electricity grids around the world. IEA ISGAN Annex 6 “Power Transmission and Distribution Systems” focuses on the potential system-related challenges in the development of future smarter grids, including technologies, market aspects, and policies. The Annex’s main goal is to facilitate the application of advanced technologies that enable power grids to maintain and improve the security, reliability and quality of electric power supply.
  • The IEA Technology Cooperation Programme on District Heating and Cooling (DHC) including Combined Heat and Power (CHP), is dedicated to helping to make DHC and CHP powerful tools for energy conservation and the reduction of environmental impacts of supplying heat. The aim of the IEA DHC Annex TS3 „hybrid energy networks“ is to promote the opportunities and to overcome the challenges for DHC networks in an integrated energy system context from a technical and strategical point of view, focussing on the coupling to electricity networks.

During the Stockholm Smart Grid week, hosted by the Swedish Energy Agency, both networks will join forces in an interactive cooperation event. Aim of the event is to create awareness on both sides on system gains from increased flexibility and resilience by coupling energy vectors. The workshop will identify concrete strengths & weaknesses, opportunities & threats of coupling DHC and electricity sectors based on the discussion of real case studies in different IEA countries and will initiate networking between key experts in the different fields. Some first results will be presented and discussed the next day during a panel session on ‘Flexibility and power system interaction and optimization leveraged by smart grid solutions’.
