Solar-wind hybrid energy system using MPPT

Energy demand is ever increasing in the world, searching for fossil fuel is done on priority basis. These fuels are not sustainable, they pollute the environment. Shortage of fossil fuels resources and adverse environment affects made use of Renewable Energy Sources (RES) as Solar energy and Wind energy essential. Solar energy and Wind energy are natural resources which are not depleted by use and are more popular. Availability and ease to obtain electric power made Solar and Wind power as alternative energy sources. Solar energy and Wind energy combined to form Solar-Wind Hybrid Power System (SWHPS), which will enhance the qualities of each other and another. To reduce the power demand on the conventional power generation sector, the optimized utilization of these natural resources is essential to produce power. Various methodologies are in practice for generation of power using Solar-Wind Hybrid System with Maximum Power Point Tracking (MPPT). Constant voltage method is used for maximum power transfer. This method should have some key features to increase the stability and efficiency.

I. Introduction

In recent years the number of technological developments on the design of prototypes for energy electricity by using energy sources not conventional, such as solar, wind, hydro, biomass and bio fuels, geothermal, cells fuels. Renewable energy sources such as Solar Energy and Wind energy are the sources that energy captured and stored by nature. A generating system with a single power source non-conventional energy does not supply electricity required^[1].
