A Fuzzy Logic Based Energy Management of Grid Connected Hybrid Energy System

On account of boundless presence and eco-friendly nature of Sustainable Energy Sources (SES) like Wind system, PV etc. power generation using SES became more captivating. This work concentrates on Energy Management (EM) of grid synchronized Hybrid Renewable Energy System (HRES) along with fuzzy logic control. Where the HRES system is a combination of solar panel and wind turbine as sources. Along with an electrical battery for energy storage via an interface using a DC-DC fused CUK-SEPIC converter with multiple input is adopted. This convertor is employed to incorporate the HRES to the main grid. In addition to grid integration a Fuzzy Logic Based (FLB) controller is employed to increase the efficiency of the system. The converter topology used is a crossbreed of wind and solar power system, which is used to eliminate the inclusion of MPPT. A two level framework is imposed, which includes a logic controller to ensure efficient EM when HRESs are interconnected with the grid. Simulation of the FLB energy management system is performed along with the implementation of hardware setup.
