Multi-objective Optimization of Combined Cooling, Heating and Power System

Abstract

This paper designs a combined cooling heating and power (CCHP) system, which realizes cooling function with an absorption refrigerator and an electric refrigerator. The main devices of the system were analyzed and modelled separately. Next, a multi-objective optimization model was established to improve the system performance in terms of energy efficiency, operation cost and greenness. Meanwhile, the population coding and selection process of multi-objective artificial bee colony (ABC) algorithm was improved to solve the proposed optimization model. Finally, the proposed optimization model was verified through simulation experiments. The research findings shed new light on the operation features of the CCHP system under the optimization strategy, and the coupling between the different objectives.
