Study of Solar Wind Hybrid Model at Leh Ladakh

Abstract

Solar photo-voltaic system, with a  reputation being inexhaustible and environmentally  benign, has been widely used for power generation. The  cost competitiveness of solar PV is likely to get even  more obvious, particularly when compared with the  continuous rising of conventional fuel prices and the  rapid decline of PV module prices. Furthermore, the  policies of India are conducive to the development of  solar projects. But solar PV suffers from its intermittent  characteristics. 

Windmill produces power when the speed of wind blows  beyond the cut-in speed. The kinetic energy of the wind is  captured and by the application of the turbine and  generator set, it converts into useful electrical energy. The  energy output from this kind of power plants is dependent  upon the wind speed. The proposed scheme integrates Solar PV and Windmills  to increase the reliability of the power supply. As both  solar PV and wind energy are intermittent, battery banks  are placed to realize the reliability of the supply. The  system operates on standalone mode. It is evident from  various studies that, in the Leh, Ladakh region wind and  Solar power production complement each other. During  the summer season or sunny days, the Solar PV share a  larger portion of generated power whereas in the winter season or cloudy day the large portion of power will be  delivered by the Wind mill. The excess power after  meeting the load demand will be stored in the battery  bank and that stored energy will be utilized when the  combined operation of Solar PV  And Windmill are not able to meet the load demand. The  proposed scheme evaluates the performance of such a  scheme and aims to optimize the system.
