Modeling of a stand-alone Wind-PV Hybrid Generation System Using (MATLAB/SIMULINK)

Abstract

The consumption rate of fossil fuels increases promptly with the rapid deterioration of mineral resources. The associated pollution problem has led the researcher's attention to the development of experimental and simulation-based different renewable energy models. However, hybrid renewable energy sources are more efficient, reliable, and cost-effective than single renewable energy sources. For unbound localities where typical electrifications are difficult to reach, a self-sustainable PV-wind hybrid system imparts a viable solution. Wind energy conversion systems (WECS) and solar photovoltaic (PV) systems are considered for this proposed hybridization of the energy source model. This project has been developed for a standalone PV-wind hybrid generation system by considering different environmental conditions on MATLAB/Simulink software. The design of both WECS and PV systems is based on mathematical expressions developed in MATLAB/Simulink. The wind turbine so called the heart of WECS consist of a permanent magnet synchronous generator (PMSG) and a rectifier for providing DC power to the load. The unregulated DC power output procured from a PV system, further regulated by a boost converter which is integrated with a maximum power point tracking (MPPT). WECS and solar PV subsystems are imparted energy to the same DC bus where the total energy is utilized for the common DC load. The presented unique performance analysis will help the researchers to explore the PV-wind hybrid generation system for further improvements.
