30 November 2021 | Online via WebEx

Featured Speaker: Mark O’Malley, Chief Scientist, ESIG and Julian Leslie,  Head of Networks and Chief Engineer – National Grid Electricity System Operator

As the power system generation mix transitions, advances in the operation and planning of the power system are required to continue to meet its primary objectives. To meet this need, select system operators on the cutting edge of this transition have collaborated with technical institutions around the world to create the Global Power System Transformation (G-PST) Consortium ( The Consortium has the objective of supporting advanced system operator cutting-edge research and development activities and supporting all system operators globally with knowledge and training as they transform their power systems.

Following an extensive and rigorous process, the G-PST defined a common inaugural research agenda to advance the operations and planning of power systems to enable the transition. The purpose of this webinar is to describe the research agenda, which seeks to include all possible advances, from fundamental to applied research, driving solutions which are expected (but not assumed) to be globally applicable to all system operators. The initial research agenda focuses on near-term issues (i.e., next decade) and includes all technical aspects of operational and planning activities within the bulk power system. These advances will vary from system to system and will range from simple modifications of existing technologies and practices to fundamentally new and better ways to plan and/or operate the power systems of the future.

G-PST/ESIG Webinar Series: Connect Faster: Improving Renewable Energy Integration With Modular Power Flow Control

8 September 2021 | Online via WebEx

Featured Speaker: Michael Walsh, Chief Commercial Officer, Smart Wires

Modular power flow control provides a uniquely effective approach to help renewable generation developers and asset owners address their most challenging transmission needs. The modern, power-electronics-based version of these devices, built upon decades of grid experience, helps balance network flows by pulling or pushing power through capacitive or inductive voltage injection. Modular power flow control has proven to help utilities plan and operate their grid to leverage this capacity, enabling new generation to be connected must faster and more cost-effectively – supporting regulatory targets while benefiting ratepayers and developers alike. In a recent deployment with National Grid Electric Transmission in the UK, modular power flow control enabled 1.5 GW of renewable generation to access the London metro area by increasing utilization of the existing transmission capacity. Solutions like this one allow rapid deployment scaling, in line with phased generation connection, further reducing upfront capital burden on developers. These standard offerings can generally be installed in 1 year or less, alleviating thermal overload-induced congestion to improve the financial feasibility of previously uneconomic renewable energy projects.

Southeast Asia Community of Practice: Tools and Case Studies for Inertia Monitoring and Calculation

27 July 2021 | Online via WebEx

System inertia has long been used by system operators to keep the frequency of the system from straying too far from normal. Historically, inertia from traditional sources (i.e., the spinning mass of generators and motor loads) were abundant and it was not necessary to monitor the amount of online inertia at any one time. But as the role of inverter-based resources (i.e., wind, solar, and battery storage) increases, inertia from traditional sources is decreasing. System operators globally have found it to be valuable to estimate and monitor the online inertia to ensure the system will respond adequately to sudden changes in frequency, even though inertia is not the only option to arrest frequency deviations. This webinar explores the diversity of methods used by system operators in Southeast Asia and globally to track inertia, giving more confidence to operators in the control room that a system in transition can operate as securely as systems of the past.
