Modeling and performance analysis of 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. Maximum Power Point Tracking (MPPT) is used to efficiently regulate the pulse width of the control signal of the boost converter in order to maintain the voltage level of the DC bus at a specific value. The system is modeled and simulated with SIMULINK software for two modes of operations: On-Grid and Off-Grid in order to examine the complementary characteristics of solar and wind power system to satisfy the load demand. Simulation results showed that the design can effectively realize the variation of RES by maintaining the voltage level of the DC bus at 240 V which satisfied the load demand at whole simulation time. The effectiveness of the proposed system was demonstrated by the simulation results and validated with detail analysis on the system´s performance.
