The Voltage and Frequency Coordinated Control for Wind-Diesel Hybrid Power System Based On Sliding Mode Method

Due to frequency and voltage fluctuation resulting from parameter uncertainties and system disturbances, the complex control strategy is designed to improve the stability for isolated wind-diesel hybrid power system. Firstly, the whole state mathematical model of the hybrid power system including static synchronous compensator (STATCOM) and battery are established. Secondly, the complex control strategy for voltage and frequency is designed by using sliding mode (SM) method. Finally, the simulation studies are designed to verify the proposed control strategy.
