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 talk will explore the capabilities to exploit fast response characteristics of an IBR to obtain superior frequency control.


Deepak Ramasubramanian is a Technical Leader at the Electric Power Research Institute (EPRI) in the Grid Operations and Planning Group. He joined
EPRI in 2017 where his work is in the area of modeling, control and stability analysis of the bulk power system with a recent focus on the associated impacts of large-scale integration of inverter-based resources. He received
his Ph.D. degree in Electrical Engineering from the Arizona State University,
Tempe, USA in 2017 and his M. Tech. degree in Power Systems from the Indian
Institute of Technology Delhi, New Delhi, India in 2013. He is a recipient of an
Energy Systems Integration Group (ESIG) Excellence Award and the Power
System Operation Corporation (POSOCO) Power System Award.
