AN TWIN PEAK BASED FLC FOR MICRO GRID CONNECTED INTEGRATED HYBRID RENEWABLE SYSTEM
In this paper, the design of a micro grid power system supplied from different hybrid renewable energy resource is proposed. The proposed system provides a highly efficient key for energy management, control and operation of micro grid fed from hybrid energy resources like wind, solar, fuel battery and ultra capacitor. Maximum Power Point Tracker (MPPT) is designed so as to attain maximum power output from the solar photo voltaic (PV) panel systems. The novelty of the proposed system fabrication in the method of Luo Converter for dc dc conversion as opposed to single ended primary inductor converter (SEPIC) A Twin Peak Detection (TPD) algorithm was introduced to determine the maximum output of renewable energy source for connect to the micro grid and other source for storage system. The Fuzzy Logic Controller (FLC) generates the signals to the converter based on the source and energy demand. The performance of the hybrid system was evaluated by simulating the models of individual units like PV panels, wind turbine, fuel, battery system and ultracapacitor under different operating conditions.
