Iranian Society of Heating, Refrigerating, and Air Conditioning Engineers (IRSHRAE) Journal of Renewable and New Energy 2423-4931 12 1 2025 03 21 Locating and optimizing the hybrid renewable power plant in arid and semi-arid climates, Case Syudy: South Khorasan Locating and optimizing the hybrid renewable power plant in arid and semi-arid climates, Case Syudy: South Khorasan 47 56 210416 10.22034/jrenew.2025.210416 FA Seyyed Mostafa Mirtabaee Faculty of Mechanical Engineering, Shahrood University of Technology, Shahrood, Iran Alireza Mostamandi Department of Art and Architecture, Hafez Shiraz Higher Education Institute, Shiraz, Iran 0009-0000-8444-7229 Journal Article 2024 02 18 Electricity generation outside the national electricity network is a method of providing energy in residential, commercial or rural areas. In the new approach, the diesel generator is combined with renewable energy technologies, firstly, the suitable location for the construction of a hybrid power plant in South Khorasan province has been investigated according to 14 indicators and 15 different options using Shannon entropy weighting method and TOPSIS decision making method. The results show that the best weight of the indices using Shannon entropy method is related to the index of distance to the road, distance to the national electricity network and population respectively. Then, among the options, Asadiyeh with a score of 0.8932 and Eshghabad with 0.8853 receives the highest score using the TOPSIS method. By choosing Asadiyeh as the best place to build a hybrid power plant, a power plant consisting of diesel generator, wind turbine, solar panel and battery has been designed to supply the consumption load of a village. The consumption of this village is 213.6 kilowatt hours per day and the peak consumption is 25.45 kilowatts. To supply this load, 9.29 kW solar panels, 2 10 kW wind turbines, 29 kW diesel generators, 18 5 kW batteries and 10.4 kW inverters are needed. The investment cost of the proposed system is 31314 euros and the production cost per kilowatt of energy is 0.0784 euros, the operating cost of this system is 3689 euros and the fuel consumption of the diesel generator during the year is 4654 liters.
