Economic optimization of hybrid renewable energy systems supplying electrical and thermal loads of a tourist building in different climates

Due to the high potential of tourism in Iran and utilization tourist buildings Iran, as well energy consumption sector, this study aims provide a feasible model for designing renewable supply system building different climates Iran. According country’s climate, 5 cities Ahvaz, Bandar Abbas, Rasht, Mashhad, Yazd were selected under study. The hybrid also consists photovoltaic panels, wind turbine, battery, converter power boilers with natural gas fuel geothermal heat pump thermal load. is used load needed preheat building’s hot water. connected electricity grid, so by selling excess electricity, net project costs (NPC) will be reduced can part its need from grid. scenarios which studied are two categories. In first category, all supplied boiler. After selecting best economic scenario Homer software added calculating required types turbines capacity 10 50 kW 25-W panels efficiencies 15.3% 18%. Finally, top-down was chosen each city. city run on criteria Mashhad an NPC $ 195,745 fraction 50.5. Using water, would save 7% reduce CO2 production 639,000 kg per year.
