Invited Talk: Dr. Chetan Mishra

Access to physics-based models for simulation studies has always been crucial to power system analysis for operation and planning. The lack of accurate and transparent dynamic models, particularly for converter-interfaced resources like STATCOMs, solar PV, data centers, and so on, is one of the main problems utilities like Dominion face. In terms of time scales of dynamics, fault current, output uncertainty, protection, and other phenomena, these resources behave very differently from well-understood synchronous machines. Even worse, control settings are only revisited when a problem “grows significant enough” to cause assets to trip offline or at least trigger comfortably set alarms. Dominion Energy will describe its initiative to develop datadriven methods for early detection of dynamic performance issues and comprehension of their mechanism as well as the difficulties involved with real-world data analysis in this presentation using a solar PV oscillation case from their system.
