Abstract - Renewable Energy Resources are best today to
stand against increasingly risk global warming and reduce the use of conventional energy sources the most important sources of such types of resources are Wind and Solar energies which are most the efficient relatively. In wind energy conversion system two masse drive train based wind turbine with zero pitch angles drives Doubly Fed Induction Generator (DFIG). The combined output of WIND/PV is converted into AC by using Synchronous Reference Frame Theory (d-q theory). A model of hybrid wind and photovoltaic system is developed in MATLAB simulation. Key Words: PV System, DFIG, Wind System, WECS, Hybrid Solar and Wind, Photovoltaic System
1. INTRODUCTION The increasing demand for conventional energy sources like coal, natural gas and oil is increased the pollution and reduction in its quantity the use of renewable energy sources like wind, solar etc. are now well developed and cost effectively reduced and largely used and it is also ecofriendly. Hybrid energy system means combination of two or more renewable energy sources like wind, solar etc. These hybrid systems can be standalone or can be grid connected. Hybrid system is more reliable because if there is any shortage of power or fault in the renewable energy sources then the loads are directly connected to the grid. The solar energy and wind energy that are used as a input sources of hybrid wind and PV system [1] . A solar system is one which utilizes solar radiation to generate electrical energy. PV cell is generally made from semiconductor material like silicon and can produce direct current from sunlight. The best silicon cell available have an efficiency of about 18%. Wind Power system is a system which converts kinetic energy of air into electrical energy. Wind power is one of the fastest growing renewable energy resources in last few years but individual energy resources either wind or solar may not be effective in terms of cost, efficiency and reliability because it is highly in irregular in nature. So hybrid wind and PV is best suitable for high reliability of power supply.

Fig. 1: Schematic diagram of proposed system In wind and solar hybrid Power system the collective power generated by wind mill and solar energy panel. For the storage of energy generated by hybrid system a battery is used. In this system power is generated by PV module when light radiation available and from windmill when wind source is available.
2. PHOTOVOLTAIC SYSTEMS Solar cell is a basically p-n junction diode fabricated in a thin layer of semiconductor i.e. silicone. The solar cell converts the electromagnetic radiation of solar energy into electricity through photovoltaic effect. When solar cell exposed to the sunlight, photons with energy greater than the band-gap energy of the semiconductor are absorbed and create some electron-hole pairs which is proportional to the incident irradiation. As the irradiation level is increased the output current of the PV cell also increased. For making the simulation modal of the PV cell we required its equivalent circuit.
