The required cold and heat are supplied by recycling the heat lost from the stimulus in combined cooling, heating, and power (CCHP) generation system. The present study proposes a new optimal arrangement for a CCHP system for annual dynamic simulation. This study uses CCHP system to design a separated stand-alone generation system to provide higher effectiveness. The system is then improved by a new enhanced metaheuristic technique, namely supply-demand-based optimization algorithm to enhance the efficiency of the designed system. The method is implemented on a hospital and its achievements are put in comparison with several different newest optimization techniques. The achievements indicate that the electricity system purchased from the utility network and fuel consumption for the optimized combined cooling, heating, and power system in comparison with the system of separated generation provides a decreasing trend.
