Noise-resilient synchrony of AC microgrids

This paper proposes distributed noise resilient techniques for the secondary voltage and frequency control of AC microgrids. The effect of noise in reference signal on the synchronization process is studied. The same communication topology for the secondary control is adopted to implement noise-resilient algorithms. The efficacy of the consensus filters and distributed least mean-square algorithm for an islanded microgrid test system under additive noise in reference signal is evaluated.
