As zero operational-cost variable Renewable Energy Sources are foreseen to dominate the future energy mix, the abundance of green electricity will allow the replacement of fossil fuels in sectors such as heating, cooling, industrial processes, and transport. The intermittency of such energy resources implies significant systemic requirements for flexible solutions; thus, developments of the energy sector in general, and the power system in particular, instigate significant innovation activities in the fields of power system flexibility. Concurrently, complexities and interdependencies of system components and multitude of actors increase the risks of service failures and the complexity of production and grid planning, raising the demand for stronger and more agile resilience means and countermeasures. In this white paper we discuss the item “How can flexibility support resilience?”, considering the increased societal needs of a secure electricity supply. A report summarising experiences from large number of initiatives in a collaborative effort between of ISGAN WG 6 and ETIP SNET WG1.

Flexibility within the electrical power system is becoming an increasingly prominent and sought-after solution, which can be utilized by both the Transmission system operator and Distribution system operator to solve/avoid network problems such as network congestion, voltage violations, system balancing etc.
To adapt to the various changes, the interaction between stakeholders within the electricity supply chain is becoming increasingly more important. These interactions, despite their various challenges, provide many opportunities for increased efficiency of the operation and planning of modern networks in the future. To utilize flexibility to its full potential, coordination between various stakeholders within the energy supply chain is required. The increased need for stakeholder interaction relies on the advanced collaboration between respective parties which needs to be facilitated through technology advancements, data exchange mechanisms, regulatory considerations, and economic analysis.
To evaluate the perspectives on the flexibility and stakeholder interaction, a survey was launched, and its findings are presented in this report. The results of this survey provide an overview of flexibility and stakeholder interaction based on the various perceptions from a wide range of respondents from different geographic locations and sectors. The survey highlights the current status of the related topics and allows for the opportunity to identify concepts, such as challenges and opportunities, which require increased attention by all stakeholders in modern power systems of the future. This work provides a foundation for future work which will be conducted in the next phase within Working Group 6 and Working Group 9.

07 June 2022 - 14:30 CEST - ISGAN Virtual Learning invites you to this panel debate on the evolution of peak load transformers.
Energy Transition and Circular Economy-related regulations are popping up around the world. Both energy efficiency and material efficiency are to be optimised. In electrical applications it is not always apparent how a trade-off between these goals can be avoided. The sustainable peak load concept for public distribution transformers does exactly that: it is beneficial to transformer energy efficiency as well as material efficiency, with no need for compromise.
This webinar will present the concept, several case studies, a thorough transformer loading survey carried out in US and a modelling exercise for the EU.
Policy makers, distribution system operators, utilities, electricity market regulators, academia, consultants, transformer manufacturers, transformer value chain.
- The total annual energy losses of a sustainable peak load unit are similar to those of a conventional unit. This is due to the fact that the average loading in public distribution networks is low, resulting in a higher relative importance of no-load losses compared to load losses.
- The material savings potential of sustainable peak load transformers is substantial, with reductions in total weight of 11 – 15%.
- The purchase cost of a sustainable peak load transformer is comparable to that of a conventional transformer if all other parameters are kept the same.

ISGAN is looking back at a very interesting 23rd meeting of its Executive Committee. Already on the first day of the 3-day meeting (March 9th-11th, 2022) two very exciting parallel sessions took place.
One focused on the continuation of work done previously in the Power System Flexibility Initiative in ISGAN. The other discussed the topic Stepping up ambition of CEM initiatives.
The second day was fully dedicated to the ISGAN Working groups. ISGAN took the opportunity of the request for extension for the next 5-year period to perform a strategy process. As a result of this a new Working Group dedicated to the dissemination and communication of ISGAN results was created. The first Programme of Work of this working group was discussed. Also, the other 5 Working groups of ISGAN presented their Programmes of Work for the year 2022.
On the third day ISGAN welcomed presenters from Mission Innovation Irmgard Herold and from the Global Smart Energy Federation, Dr. Reiji Kumar Pilai. Both presented recent developments and plans in their organizations and possible interactions as well as the Letters of Intent with both organizations were discussed.
Finally, the meeting participants acknowledged the high level of commitment and excellent work that Maarten Noeninckx has done for ISGAN. Maarten leaves ISGAN as Vice-Chair and delegate for Belgium. The work he has done over the years as head of the Budget Review Group was also very highly recognized.

05 April 2022 - 13:00 CEST - ISGAN Virtual Learning and the OSMOSE project invite you to this webinar concerning off-the-shelf inverters interfacing energy storage systems.
The speakers will lead you towards two demonstration activities part of the OSMOSE project concerning off-the-shelf inverters interfacing energy storage systems with the power grid that can be turned into grid-forming units through suitable control upgrades in order to provide several services to the power system when it hosts massive amount of inverter-based renewable/stochastic generation. This is achieved thanks to the provision of synchronisation services superposed to classic regulation ones.
Join the webinar: 2022-04-05 at h 13:00 CEST (UTC+1)
Within the context of service provision to future power systems hosting massive amount of inverter-based renewable/stochastic generation, 2 demonstrators have shown that grid forming capability can be provided from off-the-shelf equipment. One demonstration is based on a existing MW-class BESS connected to the medium voltage grid of the EPFL campus, while the other was built for the OSMOSE project by Ingeteam and connecter to the RTE network.
- Both demos proved that grid forming capability can be provided without hardware oversizing, drawing out the most of existing equipment and therefore limiting the cost.
- A hybrid system showed that supercapacitors installed on the DC side can handled all fast transients induced by grid forming control, therefore smoothing the battery output power.
- The controls have been improved to behave properly in different grid conditions including harmonics and unbalanced conditions.
- Multiservices provision can be done including grid forming capability taking into account the unit’s operational constraints.
- Accurate distribution-class PMUs can be used to assess the performance of grid forming vs grid following units.
This webinar is mainly suitable for transmission system operators (TSO), energy providers, converter manufacturers and researchers in the field of power electronics and/or power systems stability and control. The content of the webinar is also comprehensible for students and engineers with some background in the power systems dynamics.

Modelling storage operation for markets participation and supply of advanced system services (discussion paper).
ISGAN Working Group 6 (Transmission and Distribution Systems) presents you the final deliverable on the activity on 'Modelling storage operation for markets participation and supply of advanced system services', which was prepared under the lead of Italy (RSE).
The growth of power generation from Non-Programmable Renewable Energy Sources (NPRES) is accompanied by a progressive decrease of the operating hours of large synchronous generators. This increases complexity and costs, for Transmission System Operators (TSOs), to keep power system operation reliable and secure, since power flows are affected by more variability and unpredictability and, at the same time, less resources are available for frequency and voltage regulation, system balancing support and congestion management.
Thanks to their fast response, flexible control and easy scalability, Battery Energy Storage Systems (BESS) can be part of the solution mix to face such issues, by contributing to the supply of Ancillary Services (AS), both in a stand-alone configuration and in support of NPRES plants and of conventional plants.
AS include traditional ones, originally tailored to conventional power plants, and novel ones, which are gradually being introduced by TSOs to meet the new needs for prompt intervention against system perturbations.
However, services characterized by comparatively slow response times and small power gradients may require large energy contributions, which may be difficult to achieve with the BESS limited energy content, while fast services, despite requiring smaller energy contributions, are not widespread (they have been introduced mainly into isolated power systems) and still lack consolidated regulatory frameworks and remuneration mechanisms. Besides, BESS investment costs, although exhibiting a decreasing trend, are still rather high.
Therefore, techno-economic analyses are needed to understand with what performance (in meeting power exchange requests and in coping with cycling aging) and with what profitability, for their owner/Balancing Service Provider (BSP), BESS could provide single or multiple services together (to look for revenue stacking in case a single service is not enough to reach investment payback).
“Power” versus “energy” services: e.g., with reference to the Italian nomenclature,
- primary and fast frequency regulation versus tertiary frequency regulation/balancing and NPRES imbalance reduction;
- secondary frequency regulation is somewhat in-between.
- payment for availability: remuneration for power made available (e.g., Italian pilot projects called Fast Reserve and UVAM – virtual eligible units including different kinds of technology; British Enhanced Frequency Response)
- payment for activation: remuneration for energy actually exchanged (e.g., standard AS in Italy, pilot projects in Italy)
- the two forms of payment can be present together (e.g., Italian pilot projects called Fast Reserve and UVAM).
To this purpose, a dynamic response model and a stochastic optimization procedure for BESS sizing and management have been employed in this work. According to the results obtained in the simulations (mainly based on the current Italian market rules and Grid Code specifications),
- “power” services remunerated for activation may not be profitable enough for a BESS, due to the rather small energy exchanges involved (this happens, e.g., for the Italian standard primary frequency regulation). In that case, the presence of a remuneration for the power made available could be fundamental to determine the economic attractiveness of such services.
- For “energy” services, payment for activation can be profitable, due to the rather large energy exchanges involved. The actual profitability is anyway also determined by the energy prices.
- In the Italian Ancillary Service Market (ASM), e.g., upward/downward prices for secondary and for tertiary frequency regulation (and balancing) seem to be sufficiently high/low respectively, although further analyses of historical market results are needed, to understand the impact of bid acceptance uncertainty on BESS economic results and to inquire whether suitable bidding strategies could be put in place by BESS to become competitive on the ASM.
- In other European countries, these services can benefit of remuneration both for availability and for activation: e.g., in Germany and in Switzerland, all the services except Frequency Containment Reserve (FCR, which has only an availability payment). In the presence of a double remuneration, higher revenues could of course be expected; however, the specific remuneration prices should be analysed, to understand whether acceptable return on investment could be obtained.
Looking at Europe, the European Commission “Study on energy storage – Contribution to the security of the electricity supply in Europe, Final Report”, March 2020, plus a questionnaire shared among the ISGAN partners show that BESS are undergoing a fast development process, especially in Continental Europe (CE) and in Great Britain (GB). In CE, this process is mainly fostered by the high level of interconnection and by the cooperation among countries for balancing service procurement: such cooperation has already led to an integration of the platforms for energy exchange and balancing service exchange. In GB, electricity markets are very mature and exhibit a high segmentation of AS, aiming at better adapting to power system’s needs, on the one hand, and at creating business opportunities for market operators, on the other hand.
BESS are already present in many European countries, both as large stationary devices and as small distributed ones (and also as electric vehicles). They are often allowed to participate in wholesale energy exchange (on day-ahead/intraday markets) and/or in AS supply (via trading in ASMs in particular). BESS usually provide FCR and automatic Frequency Restoration Reserve (aFRR), sometimes manual Frequency Restoration Reserve (mFRR) and Replacement Reserve (RR); at present, BESS installed power devoted to AS ranges from few MW to some tens of MW to some hundreds of MW; such BESS are managed by few operators, mainly BSPs.
In several European countries, rules for BESS participation in electricity markets are the same as the ones for conventional power plants. Besides, in some countries this participation is allowed only via pilot projects, although BESS can already be aggregated together and also with loads and distributed generators. Work is still needed to overcome barriers to BESS full deployment, e.g. in terms of service technical specifications and performance requirements, market eligibility requirements, remuneration schemes.

The 23rd meeting of the Executive Committee of the International Smart Grid Action Network (ISGAN) will take place from 8th March 2022 (Tuesday) to 10th March 2022 (Thursday) as a virtual meeting. We would like to thank our UK colleagues for their strong effort over the past months to organize the ExCo23 as a physical meeting in London. Unfortunately, a physical meeting could not take place as planned due to the persistence of the Covid-19 pandemic and related travel restrictions.
During this meeting, it is planned to discuss ISGAN’s cooperation with several other initiatives, IEA TCPs, and key organizations acting in the field of Smart Grids. It is our aim to enhance the cooperation with the most relevant initiatives/organizations and to bring them to the Working Group level in order to facilitate effective collaboration and knowledge sharing activities such that it is mutually beneficial and relevant for all stakeholders.
Furthermore, the Working Groups (former Annexes) will present their results from the past year’s activites and their Programmes of Work (PoW) for the present year. For the first time, the Communication Working Group will present a unified PoW for the year 2022.
We are expecting highly dynamic and active participation from all members of the Executive Committee throughout the meeting in order to discuss, agree, and conclude on the necessary decisions to promote/continue the successful work done within the ISGAN community.
