GPST researchers at Imperial College London testing oscillation detection and identification breakthrough
Sub-synchronous oscillations are a known and manageable feature of power systems. Inverter-based resources offer some solutions for addressing these events; they also create a new dynamic within complex systems. Typical approaches for evaluating oscillation risk are limited and may not be sufficient for system-level assessments.
The EPICS Centre at Imperial College of London, which focuses on research to address the highest priorities of GPST system operators, has developed innovative approaches for detecting and identifying the sources of oscillations. Going back to the fundamental physics of power systems, the research team is working with Scottish Power, NESO, Energinet, ONS, AEMO and other operators on developing approaches that help with prediction, early warning and locational identification of oscillations, as well as post-event analysis to determine opportunities for operational improvements and prevention or mitigation approaches. This work is being presented at several forums this year and in a global webinar co-hosted by GPST and Imperial College of London.

GPST convenes operators and research institutions on power system stability and dynamics
In April and May 2026, GPST hosted invitational conversations with system operators and leading research institutions to discuss projects and initiatives tackling power system stability and dynamics. Fourteen operators shared their experiences and the innovations they are advancing in this critical field. GPST will continue hosting deep-dive conversations on topics of highest priority to our operator participants.

Growing partnership with Malaysia’s Grid System Operator (GSO)
GPST team members and technical experts at the National Laboratory of the Rockies (NLR) have built a growing partnership with Malaysia’s Grid System Operator (GSO) through a project focused on grid modernisation in Southeast Asia.
In April, building upon a years-long collaboration and community of practice in Southeast Asia, the ASEAN Centre for Energy (ACE), in collaboration with GPST, GSO, Tenaga Nasional Berhad (TNB) and the Rockefeller Foundation hosted a national workshop on battery storage planning, integration, dispatch and power system operations as part of a broader strategy to modernise power systems and deliver more reliable, affordable electricity to energy-poor and underserved communities.
Following this workshop, GSO leaders and technical directors worked with the project team at NLR and GPST to develop an efficient and creative technical exchange mechanism. NLR, GPST and HECO (the Hawaiian utility) answered 63 questions on eight grid security and EMS themes and hosted deep-dive virtual “office hours” for expert knowledge sharing.
GPST technology standards experts contribute to IEEE 2800.2 publication
On June 30, 2026, the IEEE Standards Association published IEEE 2800.2, Recommended Best Practices for Test and Verification Procedures for Inverter-Based Resources Interconnecting with Bulk Power Systems. The document, which complements the framework set out in IEEE Standard 2800, is the product of the inverter-based resources (IBR) interconnection working group, chaired by Andy Hoke, a research engineer at the National Laboratory of the Rockies and a leader of GPST standards implementation in countries around the world.
Hoke noted, “This new recommended practice helps establish a strong foundation for a reliable and secure electric power system. It is the product of over 200 industry stakeholders working together to collect and agree on best practices to make sure IBRs meet evolving grid needs.”
Jens Boemer, leader of GPST’s technical standards work stream, chairs the IEEE Subcommittee that sponsors the 2800.x series of standards and was also a key contributor. These standards support system operators because they can help ensure that those operators can tap into maximum performance capability from IBRs that interconnect to their system, and they help ensure that IBRs perform as anticipated, supporting ongoing stability in high-IBR systems.
Find the standard on the IEEE website.
See the public EPRI webinar on this new standard noted below.
GPST partners with Global Grids Catalyst and Breakthrough Energy on data schema workshop

Seven schema teams presented (CIM/CGMES, PyPSA, CESAME, SAInt, Sienna/GridDB, GenX and GDM), and the group worked together to identify shared approaches, key differentiators and common goals for future joint work in this area

ESIG completes technical report series
ESIG’s Large Load Task Force recently wrapped up a series of 11 technical reports, covering a wide range of topics including planning, forecasting, modelling, interconnecting, markets and operation. The task force represents and engages practitioners from developers and OEMs to regulators and researchers. The reports provide state-of-the-art examples, practices and emerging solutions designed to address practical gaps. The papers also support decision-makers with options that are grounded in the latest information and real-world experiences.
In addition, ESIG will host a workshop on Large Loads as a side event to the Energynautics Conference in Porto, Portugal.

CSIRO releases latest Australian electricity transition reports
GPST core team research institution CSIRO built off of its five-year track record of cutting-edge research on the GPST and Australian Research Agendas. In July, CSIRO published the final reports on 17 topics, performed by research and industry teams around Australia. CSIRO also hosted a global webinar showcasing the projects and results.
Fraunhofer introduces complementary grid forming concept: unlocking inertia from inverter-based resources
As inverter-based resources increasingly replace synchronous generation, power systems need new ways to provide stabilising capabilities such as inertia. Researchers at Fraunhofer IEE and the University of Kassel have introduced the concept of Complementary Grid Forming (C-GFM) to make better use of resources that cannot provide the full range of conventional grid-forming capabilities but can nevertheless make valuable contributions to system stability.
Two new open-access publications develop this concept. The first introduces C-GFM and a controller-independent framework for characterizing power-electronic inertia from constrained resources (read the full paper on complementary grid forming). The companion paper shows how this inertia can be tailored to the actual active-power constraints of individual resources, allowing batteries, renewable generation and other converter-connected assets to contribute according to their specific physical capabilities (read the full paper on power-electronic inertia). The work aims to broaden the range of inverter-based resources that can support future system stability and provides a methodological basis for specifying and coordinating complementary grid-forming capabilities.

GGI fossil fuel crisis task force releases ten-point plan
In response to the recent fossil fuel crisis, the Green Grids Initiative (GGI) observed that global energy systems are facing repeated crises that expose the same structural vulnerabilities each time. GGI developed a rapid-response task force and published guidance briefs on actions that can be taken to mitigate these crises. This GGI report sets out a ten-point plan of grid interventions that countries can deploy in the short term to reduce fossil-fuel dependence, ease pressures on consumers and build long-term energy security.
RMI publishes flexibility guidebook for regulators
GPST recently supported the Rocky Mountain Institute (RMI) in a technical review of a practical guidebook for regulators and policymakers on how to identify evolving reliability needs, define flexibility services and design procurement mechanisms for enhancing flexibility in highly inverter-based power systems. The report highlights case studies and examples that illustrate a framework of procurement and market design mechanisms. It also includes an appendix summarising common operational monitoring tools, the types of indicators they provide and the reliability needs they can help identify. The work was developed in partnership with the Global Energy Alliance as part of the Global BESS Consortium. As part of this publication, RMI also developed a companion report on BESS bankability and market scaling.
