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.
