•The required energy for a household in Tehran, Iran is determined.•The wind speed and solar radiation in Tehran, Iran are determined.•HOMER software is used in the analyses for both technical and economic criteria.•Five feasible systems are classified and the most economic system is identified.
The utilization of hybrid energy systems comprised of wind, photovoltaic, biomass, and geothermal technologies is growing, mainly as a result of increasing concerns about the environmental impacts caused by fossil fuels. The economic feasibility is examined here of using hybrid systems to supply the energy needs for a household in Tehran, Iran. Wind-photovoltaic-diesel hybrid systems are considered in this investigation. Hydrogen is employed by the diesel generator so as to ensure a clean fuel is used, leading to little environmental impact. In addition, battery storage is utilized in the system reliability assessment. HOMER software is utilized for the economic assessment and optimization. The key factors considered in the investigation are as follows: incident solar radiation, wind speed, electrical demand profile for the household, equipment characteristics, and hydrogen fuel costs. The average daily electricity consumption, averaged over an annual cycle, is 17 kWh/d, and the peak electrical demand is 1.5 kW, for the household considered. The electrical supply system is required to satisfy these requirements. The analysis results from the case study show that, among five hybrid systems for supplying electrical requirements, the most economical is the wind-hydrogen-battery hybrid system, which has a total net present cost of US$63,190 and a cost of energy of US$0.783/kWh (based on 2015 US$).
