Optimal Control Virtual Inertia of Optical Storage Microgrid Based on Improved Sailfish Algorithm

The optical storage microgrid system composed of power electronic converters is a small inertia system. Load switching and supply intermittent will affect the stability direct current (DC) bus voltage. Aiming at this problem, virtual optimal control strategy applied to proposed. Firstly, signal model established theoretically analyze influence damping coefficient on DC voltage obtain constraint range coefficient; Secondly, aiming defect that Sailfish optimization algorithm easy premature maturity, based leak-proof net cross-mutation propagation mechanism proposed; Finally, are optimized by improved best parameters. simulation results in Matlab/Simulink show improves as well dynamic response robustness
