Panel on Synchrophasors in Zero Inertia Grids at the IEEE SGSMA 2022

February 2022

I am grateful to the Technical Program chairs of the 2022 IEEE International Conference on Smart Grid Synchronized Measurements and Analytics (SGSMA 2022) for accepting our panel proposal titled “Towards a Zero Inertia Grid thanks to Synchrophasor Measurements”. I have been delighted to have Prof. Yilu Liu (University of Tennessee at Knoxville), Dr. Evangelos Farantatos (EPRI),  Dr. Deepak Ramasubramanian (EPRI, on behalf of UNIFI), Dr. Qiteng Hong (University of Strathclyde, Glasgow) and Dr. Krish Narendra (Electric Power Group) accept my invitations to join this panel and contribute their expertise and experiences on the matter.

What we will be talking about revolves around how the electrical grid shifting to renewables and batteries, entails the shift to resources interfacing with the power system via power electronics – inverter, rectifiers and converters. As these devices and the sources they interface are characterized by fast dynamics, the traditional control paradigm followed to the day cannot suffice. The reason is that the phenomena that used to span seconds (thanks to large rotating inertias of conventional generators), will now be unfolding in milliseconds. Hence, the operators’ response times in the control rooms will be very limited. Thankfully, synchrophasors and the applications they enable can match these time-frames and allow for the transition to a new control paradigm.

I look forward to the conference and hope to be attending it in person in the beautiful town of Split in Croatia.

Inverter Interfaced Renewables Seminar at Yale Oct. 13, News

Seminar at Yale on Inverter Control for Grids Rich in Renewables

October 2021

I am extremely lucky to have recently met and exchanged ideas and research aspirations with Prof. Leandros Tassiulas, chair of Electrical Engineering (EE) at Yale.  He has honored me with an invitation to offer a seminar to the Dept. of EE and the Institute for Network Science at Yale on October 13th. I will be presenting 2 of my earlier research works on control methods to procure active power reserves from wind generators and string photovoltaic inverters. Even though these technologies typically pursue maximum use of their aerodynamic and solar potential, respectively, they must also be able to support system stability. This becomes even more critical as renewable resources slowly dominate the grid and displace conventional resources that have until recently ensured stability. I will extend my previous results into the most recent research aspirations for a grid dominated by inverter-interfaced renewables and batteries and how such aspirations may be made possible.

The seminar will be virtual, but I will make myself available to all faculty, students & researchers at Yale, who would like us to talk before/after the seminar, so, please, do not hesitate to reach out!
