Survey on Flexibility Market Implementation and Development

The increasing penetration of renewable energy sources, alongside growing policy support for decarbonization and decentralized energy systems, has heightened interest in local flexibility markets across Europe. Within the framework of the EU’s Clean Energy Package—particularly Directive (EU) 2019/944 and Regulation (EU) 2019/943—Distribution System Operators (DSOs) are encouraged to explore flexible solutions at the local level […]
Exploring the interaction between power system stakeholders: Insights from Pilot Projects – Discussion Paper

This discussion paper provides insights from global pilot projects on flexibility for coordinated capacity management by TSOs and DSOs. The discussion paper examines key challenges and lessons learned across technical, ICT, market, economic, and regulatory aspects. The study consolidates information gathered from literature reviews, stakeholder surveys, workshops, and expert interviews to assess best practices and trends.
Active System Management by DSOs – Discussion Paper

Discussion paper that provide insights into how DSOs can leverage active system management to cost-efficiently and securely manage their grids. These insights stem from a series of interactive workshops held with members of the ISGAN WG6 and other interested parties.
Exploring the interaction between power system stakeholders: Insights from Pilot Projects
The electricity system is transforming due to renewable energy integration, decentralized generation, and digitalization. The traditional unidirectional grid is evolving into a dynamic, bidirectional system with distributed energy resources (DERs) like solar, wind, EVs, and storage. This shift, along with electrification and decarbonization goals, requires enhanced coordination to maintain reliability and efficiency.
Network Planning and Decision-Making under Uncertainty – Discussion Paper and Policy Brief

Recognizing the pivotal role of electrical grids in achieving net-zero emissions and addressing a wide spectrum of ecological, social, and economic aspects of sustainable development, ISGAN Working Group 6 joined forces with the ISGAN Communication Working Group, to spearhead a collaborative knowledge sharing project (KSP) on Network Planning and Decision-Making under Uncertainty.
How can Aggregators Improve the TSO-DSO-Customer Coordination in Digitalised Power Systems? – Discussion Paper and Policy Brief

Utilizing untapped Distributed Energy Resources (DERs) potential from customers in the distribution grid necessitates TSO-DSO-Customer coordination. Customers still face challenges how to manage and market their flexibility in the energy market and how they can become active customers. Aggregators can facilitate these flexibilities as an intermediary by providing services to different power systems participants.

How to Improve the Interoperability of Digital (ICT) Systems in the Energy Sector
This report has been prepared within the framework of ISGAN Annex 6 and focuses on the question “How to improve the interoperability of digital (ICT) systems in the (electric) energy sector?”. The paper presents and discusses various approaches for designing the system-of-systems, different approaches for enabling and verifying the ICT-interoperability in Smart Grids and motivates the need for interoperability improvements in energy sector. It does so by looking at existing approaches commonly used to improve the interoperability of digital systems both with the energy sector as in other domains, and to learn lessons from them.
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).
