Efficient energy management for the solar PVwind-battery based microgrid is deliberated in this paper. To extract more power from the solar fuzzy logic controller-based MPPT approach is employed and to produce more power from wind PMSG generators are considered. To integrate solar wind and battery energy sources diode-based bridge rectmers and bidirectional dc-dc converters are utilized. The performance of a hybrid power generation be influenced by the effective operations of these power converters. To operate these power converters more accurate fuzzy controllers are proposed in this paper. The proposed fuzzy controller-based hybrid microgrid is tested for two scenarios such as variation in RE sources with a constant load and variation in load demand with constant RE sources. Stable energy management is possible in a hybrid microgrid with the proposed fuzzy logic controllers-based power converters.
