Technical and economic study of the use of combined solar photovoltaic/waste incinerator/Rankin cycle power plant system to produce electricity in Kerman

In this research, the technical, economic and environmental feasibility for three different scenarios, including the combined system of waste incinerator/steam power plant/solar photovoltaic power plant in waste separation mode, the combined system of waste incinerator/steam power plant/solar photovoltaic power plant in the state without waste separation and the combined digester/steam power plant/solar power plant system has been investigated for the city of Kerman. Also, the effect of changing different parameters on their technical, economic and environmental performance has been studied. The results showed that the highest return on capital and cost of electricity production is 12 years and 1.17 dollars per kilowatt respectively for the combined waste incinerator system with segregation. The mentioned values were equal to 8 years and 0.78 dollars per kilowatt and 7.8 years and 0.77 dollars per kilowatt for combined systems without separation/solar and solar digester, respectively. An increase in the initial cost of solar panels by 45% causes an increase in the price of electricity and the period of return on investment by 26%, 20% and 35%. It was digested in mixed systems with separation, without separation and digestion. Also, the increase in the initial cost of the waste incinerator by 90% caused an increase in the price of electricity and the investment return period of combined systems with separation and without separation by 37% and 39%.
