Risk of Phase Incoherence in Wide Area Control of Synchronous Power Networks

no code implementations • 29 Dec 2021 • Christoforos Somarakis, Guangyi Liu, Nader Motee

We develop a framework to quantify systemic risk measures in a class of Wide-Area-Control (WAC) laws in power networks in the presence of noisy and time-delayed sensory data.
