Determining the optimum size of the prime mover of combined cooling heating and power (CCHP) systems due to significant impact on energetic, environmental and economic results of these systems is very vital and essential. In this study, based on energy, exergy, environmental, and economic (4E) analysis the optimum capacity of the gas engine (GE) for CCHP systems have been investigated. The evaluation study performed by using a proposed evaluation function (EF) and genetic algorithm (GA) optimization methods for a sample official building in Iran. Regarding eight constraints, the optimum size of GE based on EF and GA optimization methods calculated 70 and 74.3437 kW, respectively. By comparing the results obtained from EF and GA methods, it was concluded that EF method calculate the same optimal capacity with little difference and with the same accuracy of GA method. This is while proposed EF method does not have the complexity of GA optimization algorithm and is simpler. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

a b s t r a c tThis paper construct a CCHP and renewable energy based hybrid energy system driven by distributed energy resources (DERs CCHP). Then, the paper constructs performance indexes from energy, economic and environment. Thirdly, the paper proposes a multi-objective optimization model for DERs CCHP system under four optimization of energy rate (ER), total operation cost (TOC), carbon dioxide emission reductions (CER) and joint optimization. Finally, Guangzhou Higher Education Mega Center (GHEMC) in China is taken as the object for comparatively analyzing the operation performance of DERs CCHP system and CCHP system driven by natural gas (NG CCHP system). Results show: Joint optimization mode could balance the results of different optimization modes. DERs CCHP system shows better operation performance. ER of ER optimization, CER optimization and joint optimization are higher than that of NG CCHP system. NPV of all optimization modes is positive, IRR are bigger than the expected yield rate. DERs CCHP system could reduce CO 2 emission by utilizing wind energy and solar energy to replace NG. The sensitivity analysis indicates the performance of the DERs CCHP system will become better with the increase of chiller COP, decrease of NG price and wind-photovoltaic equipment cost.
