Integration of Solar-Wind Hybrid Power System for Residential Application

This paper describes modeling and presenting performance analysis of PV/Wind/Battery Hybrid Power System (PWB-HPS) for residential applications. The main aim is to maximize the use of Renewable Energy Sources (RES) to meet the load demand by selecting the optimal configurations of the proposed PWB-HPS. The system consists of two Photovoltaic (PV) panels inclined in two different directions, one Wind Generation System (WGS) and Battery Storage (BS) connected to a DC bus and then to the AC side through pulse width modulation inverter .In order to extract maximum power from Wind energy and solar energy systems a novel technique, known as Maximum Power Point Tracking (MPPT) technique, has been adopted, in this paper. Additionally, to maintain and sustain the continuity of supply to the load on demand at all times, the outputs of wind energy and solar energy are integrated suitably .For wind generator, the overall operation is based on the estimation of the speed that is basically a sensor-less rotor speed estimator, which in fact avoids all mechanical sensors. The rotor speed so estimated, is used to control the turbine speed by maintaining the input dc quantities (Voltage and Current) for boost converter. Simulation studies of the proposed system are carried out using MATLAB / Simulink platform, and results are presented.
