The objective of this paper is to provide a control scheme of a power flow management of a grid connected hybrid PV-wind-battery. The hybrid PV-wind-battery system is connected to a multi-input transformer coupled bidirectional dc-dc converter and using a fuzzy controller. The power from the PV along with battery charging/discharging is controlled by a bidirectional buck-boost converter. The power from wind is controlled by a transformer coupled boost half-bridge converter. A single-phase full-bridge bidirectional converter is used for feeding ac loads and interaction with grid. The proposed converter design has lessened number of power transformation stages with less segmentally, and diminished misfortunes contrasted with existing grid-connected hybrid frameworks. In this proposed work analyzing the multi response of a grid connected hybrid PV-wind-battery in different cases. In the proposed system has two renewable power sources, load, grid and battery. Hence, a power flow management system is essential to balance the power flow among all these sources. The main objectives of this system are as follows: • To explore a multi-objective control scheme for optimal charging of the battery using multiple sources. • Supplying un-interruptible power to loads. • Ensuring evacuation of surplus power from renewable sources to the grid, and charging the battery from grid as and when required. The performance of the control strategy for power flow management under various modes of operation was examining by using MATLAB® Simulink Software.
