Modeling and Performance Evaluation of a Grid-Connected Photovoltaic/Wind Hybrid Power System

Abstract

Using renewable energy technologies in Egypt returned to the abundance of solar irradiation and wind speed. The purpose of this paper is to investigate the dynamic modeling and performance analysis of grid-connected hybrid renewable energy system (HRES). This system consists of constant speed wind turbine (CSWT) and photovoltaic (PV) station integrated with the utility grid. Maximum power point tracking (MPPT) technique and unity power factor operation are obtained in PV station by using a controlled power converter. The performance of HRES is examined using MATLAB Simulink software. Moreover, the system is validated through realistic data based on actual wind speed and solar radiation measurements for Zafarana, Suez Gulf region, Egypt. The simulated results prove the effectiveness of the controlled converter for capturing maximum energy along with working with unity power factor. Depending on the simulation results, the electricity production of the HRES per GWh is estimated.
