Download Presentation View Webinar Recording Featured Speaker: Peter Markussen, Senior Director, Energinet Peter Markussen About the Webinar: Europe has significant interregional transmission, with about tens of GW of interregional transfer capability built during 2008-2022. MW Targets are established between TSOs and on average, 70% of the capability of these interconnections is required to be available in the day-ahead and intra-day markets. In this webinar, Peter Markussen of Energinet will discuss how Europe set these targets, why there is support…

Download Presentation View Webinar Recording Download Q&A Featured Speaker: Ryan Quint, Director, Engineering and Security Integration, NERC Ryan Quint About the Webinar: The industry relies on accurate and validated models that match reality in order to plan, design, and operate the bulk power system. When models do not match reality, this introduces potential risk for the grid being operated in a unknown and unprepared operating state. When the vast majority of models are deemed inaccurate or insufficient to identify abnormal…

G-PST/ESIG Webinar Series: Understanding Grid-forming Inverter Specifications
Download Presentation View Webinar Recording Featured Speaker: Ben Kroposki, Director – Power Systems Engineering Center, National Renewable Energy Laboratory About the Webinar: Inverter-based resources (IBR) such as photovoltaics, wind, and battery energy storage systems are increasingly being deployed to meet clean energy targets around the world. These systems have traditionally been designed as grid following where they need to have a voltage waveform provided by the system to synchronize to. As synchronous generators from traditional fossil-fuel plants are removed from…

Download Presentation View Webinar Recording Featured Speaker: Benjamin Hobbs, Theodore and Kay Schad Professor of Environmental Management, Johns Hopkins University About the Webinar: Today's power market designs were fashioned primarily for systems with dispatchable, non-storable generation-- are those designs "fit for purpose" for tomorrow's systems dominated by wind, solar, and battery resources? Although many of the fundamental principles will still apply in the future, there are several reforms that will be critical if we want to get the full economic…
