Mathematical Modeling and Evaluation of Performance Characteristics of a Hybrid Solar PV and Wind Energy System

Abstract

Solar Photovoltaic (SPV) and wind energy are two major sources of renewable energy that are intermittent in nature. A hybrid system consisting of SPV and Wind Energy Conversion System (WECS) can meet the energy needs as either of the sources continues to generate energy, in the absence of the other, that is reliable and cost-effective. The paper presents detailed mathematical modeling, simulation, and performance analysis of a single cell SPV and Permanent Magnet Synchronous Generator (PMSG) based WECS. These two sources are integrated to form a hybrid renewable energy system. The hybrid model is simulated and the overall performance is analyzed using MATLAB/Simulink for varying temperature/irradiation conditions and varying wind speeds for SPV and WECS respectively. Performance characteristics of the hybrid PV and WECS are presented. The paper also presents as a case study, the annual energy generation for a chosen location from individual SPV and WECS systems based on the real time data collected from the Solacast website. This study evaluates the feasibility of the implementation of a hybrid system at the site.
