Abstract: 

In allusion to the output power fluctuation of intermittent energy source in the photovoltaic (PV)-storage distributed generation system, the fuzzy control strategy based on the hybrid energy storage system between battery and super capacitor (SC) is established in PV-storage distributed generation system. In view of the power management and energy distribution between the battery and SC two energy storage units, the output of fuzzy control of present charging/discharging capability of the hybrid energy storage system is utilized. Target power value is determined firstly, according to the battery and SC charged state synthetically, the deviation value beyond the target power value is allocated according to the fuzzy control theory between the two kinds of energy storage medium. The effectiveness of the proposed strategy is validated by results of the case study.
