Optimal Sizing of PV, Wind based Grid Connected Hybrid Renewable Energy Systems for Rural Areas in Presence of EVs

This paper represents the need for optimization of a HRES which comprises solar, wind and battery. In this paper a detailed study of a system which is connected to a grid and combined with different kind of renewables is given. The location used in this case study is Siliguri, West Bengal. Here, the whole simulation study has been done in Hybrid Optimization Model for Electric Renewables (HOMER) software. The geographic location of the study area is 26°43.6’N (lat) and 88°23.7’E (long) respectively. The objective of this paper is to get a reliable independent system and levelized cost of energy. Two loads have been connected to the system, one is a household load and the other load is for charging of an electric vehicle and renewables such as PV and Wind has been used. The optimum architecture means the size of the PV array, wind turbine, and number of battery string, are optimized by HOMER. Homer helps in optimizing the cost and it calculates the cost of energy (COE) and net present cost (NPC). By the help of NPC and COE, we can find the best system and proper modifications can be done. The optimization result shows that the system consisting of PV, Wind Turbine, Converter and Grid is the superlative system when compared with COE and NPC of system.
