Techno-economic-environmental study of hybrid power supply system: A case study in Iran

This paper presents an optimal planning model of a hybrid renewable energy system to meet a real load with a combination of photovoltaic panels (PV), diesel generators and batteries. Also, replacing the conventional energy storage system with a fuel cell is investigated. Energy Modelling and Energy Resources Assessment Lab (EMERAL), at University of Tehran, in Tehran, Iran has selected as a case study. A technical, economic and environmental assessment was conducted for optimal planning of the hybrid energy system. Finally, the impact of diesel fuel price fluctuation on the economic competitiveness of proposed hybrid renewable energy systems in providing off-grid electrical load demand is investigated. In this study simulation, optimization and modeling procedures are done by HOMER software.
