Abstract

This manuscript presents the hybrid renewable energy system using wind-solar and DC-DC CUK converter and three phase dc to ac converter with LC filter. The wind and solar are environment friendly and abundantly available energy sources in India. The solar and wind are intermittently available renewable energy resources, resulting into the generation of fluctuating output from the hybrid system, which will damage the electrical appliances designed to operate on the stable system. The modelling of the cuk dc-dc converter, three phase dc-ac converter and inductor-capacitor filters simulation is done using Matlab. The different blocks of the hybrid systems like wind and solar model, cuk converter and inductor-capacitor filters are built separately before interconnecting them to form the complete DC hybrid system with main grid. The inputs for the simulation are: varying wind speed and changing irradiance. The simulation results show that the hybrid systems possess high reliability as compared to stand alone system. The addition of cuk converter, three phase dc-ac converter and inductor-capacitor filter to the hybrid system greatly reduces the fluctuation in the output.Keywords: Battery, wind energy, photo voltaic cells, converters, hybrid power systemCite this ArticleGonal Veeresh S, Sheshadri GS.
