Applying Three Port Converter with Dual Battery Storage System for Hybrid Power Generation

640-646The proposed research work used three power sources, namely wind energy, solar energy and grid. Wind and solar constitute the primary energy sources while the grid acted as the secondary one; added to that, we have the battery storage system. The priority between the two forms of energy in the primary source is determined by their availability. The solar irradiance is available during daytime, whereas during cloudy and night times, energy extraction is impossible; besides that wind energy is also not reliable. Thus the central level controller (CLC) is used, which serves as a deciding authority for the selection of primary source. When none of the energies in the primary sources are available the grid supplies the required power to the load. When there is a surplus energy from primary sources, it is stored in a battery or exported to the grid. In addition DBSS is also introduced for effective utilization of battery storage system. The proposed model is connected with micro grid to provide utilization path for surplus power. The overall design and simulation is performed by using MATLAB/SIMULINK
