Abstract

In this paper, a control strategy for power flow management of a grid-connected hybrid based system with an efficient synchronous coupled converter is presented. The proposed system aims to satisfy the load demand, manage the power flow from different sources, inject surplus power into the grid and charge the battery from grid as and when required. A boost half-bridge converter is used to harness power from wind, while bidirectional buck-boost converter is used to harness power from PV along with battery charging/discharging control. A single-phase full-bridge bidirectional converter is used for feeding ac loads and interaction with grid. The proposed converter architecture has reduced number of power conversion stages with less component count, and reduced losses compared to existing grid-connected hybrid systems. This improves the efficiency and reliability of the system. The effectiveness of the topology and efficacy of the proposed control strategy are validated through detailed experimental studies, to demonstrate the capability of the system operation in different modes.
