Paper Abstract

In this paper, control and power management system of PV-Battery hybrid system in two modes of operations gridconnected mode and islanded mode is proposed and investigated. In this configuration power flow from PV is used as primary power source and battery is used as a storage system to deliver power to the loads and utility grid through DCDC converters and an inverter. Wide bandgap semiconductor devices with higher switching speeds and higher efficiencies such as silicon carbide (SiC), and Gallium Nitride (GaN) devices will become a critical component in building microgrids. So, the impact of using GaN based Inverter on energy efficiency and power quality needs to be investigated. The power management system balances the power flow of the system under any operating circumstances such as: load demand changes, switching between operating modes disturbance, or changes in irradiance or temperature for solar energy. Multiple case studies are simulated to verify the effectiveness of the system. The PV-Battery hybrid system and power management system are simulated in PSIM and MATLAB/Simulink platforms.
