Updated GPST Research Agenda Now Available
GPST released an updated Research Agenda in December 2025, outlining priority technical questions facing power systems with rapidly evolving resource mixes and demand patterns. Building on the inaugural agenda, published in 2021, this edition reflects collaboration between power system operators and leading researchers worldwide. It draws on insights gathered through written reviews, topical dialogues, one-on-one exchanges, and in-person discussions at the Global System Operations Summit in Berlin, co-organized with 50Hertz.
The revised agenda confirms core priorities while introducing new emphasis areas aligned with the changing needs of modern power systems. New additions include a section on distributed energy resources (DERs) and the services they provide to the bulk power system. The agenda also expands its focus on large electrical loads and their interactions with inverter-based resources, as well as system oscillations and multi-factor events.
Imperial College London is also updating GPST’s research landscape analysis, with findings expected to be shared later this year through GPST’s Research Repository and a forthcoming report. GPST will also host six deep-dive webinars in 2026 to further explore the new Research Agenda, including operator-only discussions and public sessions examining priority topics.

GPST Hosts Technical Sessions at Global System Operations Summit in Berlin
Transmission system operators, researchers, and technology experts gathered in Berlin from 24–26 September 2025 for workshops hosted by 50Hertz Transmission GmbH. The workshops focused on digital control centers, congestion management, and operational challenges associated with increasing shares of inverter-based resources.
GPST contributed several technical sessions. A dedicated EPICS discussion examined sub-synchronous oscillations in inverter-based resource dominated systems, with contributions from Mark O’Malley and Balarko Chaudhuri (Imperial College London), Xiaoyao Zhou (NESO), and Callum Henderson (Scottish Power). Additional sessions included presentations by Lina Ramirez (GPST) on real-time system strength monitoring and human factors in control room design, as well as discussions led by Imperial College London researchers on evolving control room applications and system physics. The summit also featured a session on the 2025 GPST Research Agenda, led by Mark O’Malley, Michael Nestor, and Andrey Churkin (Imperial College London), and moderated by Karin Wadsack (GPST).
We are looking forward to co-organizing the next Global System Operations Summit with 50Hertz in Berlin on 17–18 September, 2026. To receive updates and first notice of registration, sign up on the 50Hertz website.
Resource Adequacy in an Era of Grid Uncertainty
Figure 2 – The relationship between resilience, and its key components in the context of the electric grid: resource adequacy, operating reliability, and contingency preparedness.
GPST authors published a peer-reviewed paper examining how resource adequacy assessment and reliable portfolio procurement are evolving in response to increasing complexity on the electric grid. Published in IEEE Transactions on Energy Markets, Policy and Regulation, the paper reviews global literature and industry practice to assess how planners are adapting to changing risk conditions, including correlated outages, inverter-based resources, flexible demand, changing weather patterns, and rapid load growth.
The work identifies seven emerging best practices for modern resource adequacy assessment, introduces an updated approach to capacity accreditation, and outlines areas where industry practice is advancing alongside, and in some cases still falling short of, current research. The paper builds on insights from a 2023 GPST workshop series, including an in-person meeting in Washington, D.C., that convened experts from system operators, regulators, academia, and industry to examine key challenges in modern resource adequacy and market design.

Knowledge-Sharing Supports Development of South Africa’s Transmission Asset Management Center
South Africa’s National Transmission Company (NTCSA) engaged with GPST to inform the development of a new transmission asset management center. Through GPST’s operator-to-operator network, NTCSA connected with ISA Interconexión Eléctrica, Colombia’s transmission system owner, which operates an established asset management center. ISA shared practical insights on center functions, data collection practices, and digital tools used to support asset monitoring and long-term performance. The exchange also covered implementation considerations, including cross-department coordination, lessons from ISA’s development process, and approaches for tracking reliability and operational outcomes. By facilitating knowledge exchanges between system operators, GPST helps ensure emerging transmission initiatives benefit from operational experience and practical implementation insights.

The Australian EPICS International Workshop, hosted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Newcastle, Australia, from 27–30 January 2026, focused on advancing practical approaches to power system modelling, engineering strategies, and grid planning for systems with increasing shares of inverter-based resources.
As part of the EPICS Global Centre initiative, the workshop supports the development of modelling frameworks, engineering tools, and economic analysis capabilities to address evolving power system challenges. Sessions explored system services, techno-economic analysis, and emerging planning needs, with contributions from GPST partners including John Ward (CSIRO), Ben Hobbs (Johns Hopkins University), and Mark O’Malley, who participated in a panel on analytical and operational approaches to modern power systems.
The workshop brought together 66 participants from research institutions, industry, and system operators, and featured 17 student and postdoctoral research posters, highlighting emerging work and opportunities for continued collaboration.
Partner Updates
ESIG Expands Global Collaboration
The Energy Systems Integration Group (ESIG), a GPST Core Team member organization, is expanding its peer-to-peer collaboration model beyond the United States to connect power system practitioners across regions. The effort will broaden participation in ESIG working groups, convenings, and analytical activities, bringing in perspectives from rapidly evolving power systems in Europe, India, Southeast Asia, and other markets.
ESIG is also developing regional work programs and plans to launch a multilingual online education platform later this year to make technical resources more accessible to a wider set of practitioners. GPST continues its partnership with ESIG and looks forward to working closely with ESIG International as both organizations advance technical collaboration and knowledge exchange across power systems.

Developing a Framework for Power System Stability
Representatives from GPST participated in expert review meetings for the Power System Stability Needs Assessment Framework, led by Agora Energiewende and developed by Energynautics. The project is developing a structured methodology to assess system stability in power systems with increasing shares of inverter-based resources, using measurable indicators across key stability dimensions such as frequency, voltage, oscillatory, and subsynchronous stability. These indicators are designed to translate emerging stability needs into clear action triggers and solution pathways for planners and policymakers. The review meetings brought together international experts to share input on current assessment practices and how they can be reflected through measurable metrics. Additional updates are expected in the coming months, with a formal launch planned for the Wind & Solar Integration Workshop in Porto (September 29 to October 2).
IEA Report Examines AI’s Growing Impact on Energy Systems
The International Energy Agency’s report Energy and AI examines the relationship between artificial intelligence and the energy sector, including the implications for electricity demand and the role of AI in shaping future energy systems. GPST contributor Seong Choi served as a technical peer reviewer, providing expertise to strengthen the report’s analysis and support its relevance for policymakers, industry leaders, and researchers.
