Abstract: Wind/PV generation system has been a new choice to supply electricity to out-of-grid regions. The authors took Baoying lake as example and conducted a series of optimized matching experiments and concluded that fishermen’s household electricity demand could be fulfilled when the value of wind machine was set at 150W and that of PV cell was 85Wp. In the meantime, the paper also took advantage of Cost/Benefit method to analyze the PV/Wind system and considered the specific system was economical, feasible and suitable to be widely used in such areas.
