Abstract :
Two effective control strategies were described in this paper respectively when the microgrid (MG) operated in grid-connected mode or islanded mode. For islanded operation mode, a novel cooperative control strategy of energy storage system and microsources (MSs) was proposed in details. The proposed control strategy improved the shared power requirements among the DG units, power and restore frequency balance and the dynamic response when the MSs generation or power demand of local loads changed. A MG system simulation platform is formed by two 3kVA parallel connected PV inverters and a battery energy storage system. Simulation platform adopted multi-master structure for improving reliability of the MG is established in Matlab/Simulink. Simulation results verified the feasibility of the proposed approach.
