Research on Bi-Directional Inverter of Wind-Solar-Diesel Hybrid Generation System

A bi-directional inverter for AC bus wind-solar-diesel hybrid generation system is studied in this paper. Topology of power circuit is optimized. And novel current decoupling deadbeat control strategy is adopted in current loop to improve dynamic performances. Small capacity prototype is implemented based on dsPIC30F3011.The experimental results show that the bi-directional inverter has unity power factor and can realize bi-directional power flowing.
