Mathematically Modeling of PV-Wind Hybrid System

Rubina Chaudhary, Ranjana Khandare

Abstract


The study of hybrid (Photovoltaic and wind) generation is used system which is consist of 1 kW wind and 1 kW PV. The solar radiation data and wind data of the School of energy Environmental studies from D.A.V.V Indore are analyzed for sizing of the renewable energy system. The output power of a wind turbine at a specific location depends on many factors, the amount of available energy increases with the increase in wind speed. It follows a cubic relationship between output of wind energy and wind speed. The output of photovoltaic varies with PV module rating and derating factor (%) of PV module. The monthly average solar radiation (2019) taken by Solar electricity hand book 2019, Indore mp (India) is 4.36 KWh/m2). The average wind speed of Indore, Madhya Pradesh, (India). Which were recorded by world weather online between January-December 2018, (3.1 m/s) 2019, (3.1 m/s) 2020, (2.00 m/s). According to mathematical analysis it is determine that for the same rating, the output power of wind is comparatively much less than photovoltaic and the highest output power is of hybrid system (combination of wind and photovoltaic. As literature survey indicates that the wind machines are not designed, developed and tested for low wind regions for power generation (region between 1 to 6 m/s). Commercialization of low wind speed machines needs the larger parts of world to meet the decentralized small electrical demands especially in residential and agriculture sectors. It may also be used in commercial sector, agriculture sector and in some remote distant establishment.
