Multi-input Inverter for Hybrid Wind-Photovoltaic Standalone System

Abstract

The rise in the use of alternate energy sources such as solar, wind, geothermal, fuel cell, etc. is due to the fast depletion of conventional energy sources. However these sources are less reliable due to their intermittent nature. To effectively utilise these energy sources, hybrid power systems with more than one renewable energy is used. One type of hybrid power system is a combination of PV energy and battery. The battery is utilized whenever the power from the solar panel is unavailable. Another type of hybrid system is the combination of photovoltaic and wind systems. This paper presents one such combination of hybrid power system with wind and solar energy as two inputs to a multi-input inverter which is supplying a load of 1kW. The simulation of the model is created using MATLAB/Simulink for input dc sources and for solar and wind sources.
