Frequency Control in a 100% Inverter Based Grid

Featured Speaker: Deepak Ramasubramanian, Senior Engineer Scientist, EPRI

Deepak Ramasubramanian is a Sr. Engineer Scientist at the Electric Power Research Institute (EPRI). He joined EPRI in 2017 where his work is in the area of modeling, control and stability analysis of the bulk power system with recent focus on the associated impacts of large scale integration of converter interfaced generation and distributed energy resources.

Webinar Abstract: The changing resource mix of the bulk power system, particularly the increasing deployment of wind power and solar PV, has resulted in an increasing portion of the resource mix being asynchronously connected through inverters – Inverter Based Resources (IBRs). These resources behave differently than traditional synchronous resources, which has necessitated investigation into viable alternate control schemes for use during operation of the system. A major theme of alternate schemes proposed in research has been on ensuring that these IBRs conform to the operational norms and limits that are presently followed. However as a faster response can be obtained from IBRs, this webinar will first pose the question of whether there is really a need to make IBRs conform to a slower operational paradigm which reflects synchronous machine operation. Or can the fast response characteristics of an IBR be leveraged to obtain superior frequency control?

About G-PST Consortium

The chief executive officers of National Grid Electricity System Operator UK, California Independent System Operator (CAISO), Electric Reliability Council of Texas, Australia Energy Market Operator (AEMO), Ireland’s System Operator (EirGrid), and Denmark’s System Operator (Energinet) are champions in developing the consortium mission and activities. Importantly, these system operators are leading a Research Agenda Group to identify common, cutting-edge research questions that can inform large- scale national research and development investments. Relevant results and lessons from this process will be broadly shared for learning across all countries. The Consortium is also partnering with around 10 emerging economy and developing country system operators from Africa, Asia, Latin America and Eastern Europe who will also guide the G-PST vision and collaborate with the Consortium to advance power system transformation with a focus on technical collaboration, peer learning and exchange, and workforce development to support local PST priorities.

A core team, including the Energy Systems Integration Group (ESIG), Imperial College London, Council of Scientific and Industrial Research (CSIR), Fraunhofer Cluster of Excellence for Integrated Energy Systems, National Renewable Energy Laboratory, Latin American Energy Organization (OLADE), IEEE, Electric Power Research Institute (EPRI), Commonwealth Scientific and Industrial Research Organization (CSIRO), the Danish Technical University (DTU), and ASEAN Center for Energy, is actively developing the consortium and will be engaged in implementation of technical work as well as coordinating specific pillars.

International agencies and multilateral and regional development banks, including World Bank, United States Agency for International Development (USAID), German Agency for International Cooperation (GIZ), International Energy Agency (IEA), Asian Development Bank (ADB), European Bank for Reconstruction and Development (EBRD) and others are serving as key implementing partners to ensure the consortium complements and reinforces existing programs.
