Graph Laplacian Spectrum and Primary Frequency Regulation [PDF]
2018 IEEE Conference on Decision and Control (CDC), 2018 We present a framework based on spectral graph theory that captures the interplay among network topology, system inertia, and generator and load damping in determining the overall grid behavior and performance. Specifically, we show that the impact of network topology on a power system can be quantified through the network Laplacian eigenvalues, and ...
