Power flow control strategy of PV hybrid module system with energy storage

In this paper, an power flow control strategy of a hybrid module type photovoltaic(PV) generation system with energy storage is presented. This system consists of the current source converters to perform the maximum power point tracking(MPPT), a grid connected H-bridge inverter and a bidirectional converter for energy storage. In this system, in order to improve the utilization of PV energy and stabilize the power control, the control strategy is in need of improving. This control strategy is designed by analyzing the residential power consumption and irradiance condition in a day. Through the theoretical analysis and simulation results, proposed control strategy for PV hybrid module system with energy storage is verified.
