A standalone hybrid energy system modeling for academic institution

Strict environmental regulations and continuously increasing electricity demand have resulted in interest for the utilization of renewable energy sources. This paper investigates the feasibility of a stand-alone hybrid energy system to meet out electric load requirements of JK Lakshmipat University, Jaipur. In order to maintain continuity of electricity supply, a single energy source is not a good option. So, we have considered a hybrid system having wind turbines, solar PV system, and diesel generator with the integration of battery bank. Load scenarios for both summer and winter season have been considered for modeling of proposed hybrid energy system. Techno-economic analysis for proposed system model has been performed using HOMER software. Variation in load for a month and a year are considered as 10% and 20% respectively. The cost of energy is coming out to be 0.462 $/kWhr, which is quite comparable with contemporary hybrid renewable energy technologies. As university has two diesel generators of 600 KVA and 250 KVA, but HOMER software suggested 250 KVA generators only, which will also help to reduce emission level significantly.
