POWER MANAGEMENT AND CONTROL FOR HYBRID PV/BATTERY DC MICROGRID

This study proposes an effective power management and control strategy for standalone PV/Battery hybrid dc microgrid. Maximum available power for a given instantaneous environmental conditions from a photovoltaic (PV) is extracted by maximum power point tracking (MPPT) algorithm. DC bus voltage is regulated by compensating the mismatch power between PV power generation and load demand by optimal charging and discharging of battery under stand alone mode condition. The double loop control is implemented for both PV boost converter and Battery buck/boost converter. The proposed work has been validated through MATLAB/Simulink results under different environmental and load conditions.
