Control and energy management of a grid connected hybrid energy system PV-wind with battery energy storage for residential applications

This paper presents the control and energy management of a hybrid system that comprises wind (Doubly Fed Induction Generator DFIG) and Photovoltaic (PV) generation subsystems, a battery bank, and an AC residential load, connected to the utility grid which is used as a backup source. The objectives of this system are, primarily, to satisfy the house load power demand and, second, to manage the power between its different components. A comprehensive nonlinear model and a control design of the studied power system have been developed in this paper. Simulation results using MATLAB/Simulink illustrate the performances of the proposed supervisor controller under several operation modes.
