Abstract

In this paper, a control strategy for power flow management for a grid-connected hybrid photovoltaic (PV)–wind battery based system with an efficient multi input transformer coupled bidirectional DC–DC converter is presented. The proposed system works on with to satisfy the load demand, manage the power flow from different sources, inject the surplus power into the grid, and charge the battery from the grid as or when required. A transformer-coupled boost half-bridge converter is used to harness power from wind, while a bidirectional buck–boost converter is used to harness power from PV battery charging or discharging control. The proposed converter architecture has reduced number of power conversion stages with less components and condensed losses compared with existing grid-connected hybrid systems. This improves the efficiency and the reliability of the system. Simulation results obtained using MATLAB/Simulink shows the effectiveness of the proposed control strategy for power flow management under various modes of operation.
