Design and Simulation of a PV System with Battery Storage Using Bidirectional DC-DC Converter Using Matlab Simulink

PV (Photovoltaic) module consists of couple of solar cells in the series and parallel combination used to convert solar radiation into electricity. They are among the most well-known source of renewable energy. Due to the absence of hazardous emissions, solar energy is on par with fossil fuels in terms of the environmental benefits it provides. To build a PV system with battery storage, we employed a MPPT controller, that maximized the power output, a PI based voltage controller that maintained the voltage profile across the output. The simulation results showed that the system was able to meet the load requirement in the isolated mode. In addition to that use of energy storage devices and to support the battery a bidirectional DC-DC converter has been used in the paper. To managed the generated power across the renewable energy sources as well as to deals with the system uncertainty the requirement of energy storage systems also has been increased. The simulated result presented in the paper concluded that for various renewable energy sources like solar, wind, etc., batteries are an ideal energy storage solution to provide the support in the isolated DC system.
