Decentralized frequency support control based on distributed PV’s adaptive power reserve

Abstract High integration of PV diminishes system inertia, which jeopardizes the frequency stability. Adjusting PVs’ output according to demand is an active power control method requiring no energy storage devices, realizes grid support by a certain reserved PV. To equally reserve between different PVs without communication, this paper combines operation characteristics module on right side maximum point and proposes characteristic adaptive reserve-frequency supporting control. Furthermore, irradiance temperature sensors, cumbersome mathematical computation, accurate measurement parameters can be eliminated. Finally, simulations are provided validate effectiveness proposed strategy.
