Optimization and Management Strategy of Grid Connected Hybrid Renewable Energy Sources

Abstract

This paper represents an optimization method as well as energy management strategy of grid connected renewable energy sources for multi house. Optimization method has been accomplished using HOMER software to bring out optimal size of renewable sources and other components for management strategy. The main purpose of this paper is to design an energy management strategy to optimize the cost and minimize the power loss of extracted power from renewable energy sources based on Fuzzy Logic Controller (FLC). The system consists of PV array, AC wind generator, Battery, Converter and grid. FLC monitors load profile and delivers a signal to sources. Then FLC changes the switch for appropriate energy supply according to fuzzy rules. The management strategy is controlled by FLC in a way that extra power after meeting the energy demand of the house can be sold to the national grid which is more useful and cost feasible than any other conventional systems. The proposed management strategy is more effective than any other traditional systems which must minimize power loss.
