On the Achievable Inertia Constant of Inverter Based Resources
Christos M. Nikolakakos, Hassan Haes Alhelou, Nikos Hatziargyriou
As inverter-based resources (IBRs) displace synchronous generators, the inertia they can actually contribute to the grid becomes a critical planning parameter. Unlike synchronous m…

Frequency Measurement Practices for Inertia Assessment in Inverter Based Resources Dominated Power Systems
Christos M. Nikolakakos, Hassan Haes Alhelou, Nikos Hatziargyriou
Transmission system operators and protective relays compute the rate of change of frequency (RoCoF) from frequency averaged over tens to hundreds of milliseconds, as standards and…
