The invention relates to an optimization method for a combined cooling, heating and power system, comprising the following steps: establishing a combined cooling, heating and power system model, selecting a combined cooling, heating and power micro-grid as an optimization object, and mathematically modeling the equipment in the scene ; Determine the decision variables and objective functions for the optimization analysis of the combined cooling, heating and power system; determine the constraints on the optimal operation of the combined cooling, heating and power system; select the whale optimization algorithm and introduce chaotic cubic mapping and mutation rules to optimize the initial population and behavior rules; The mixed heat-fixed power strategy is used as the operation strategy of the combined cooling, heating and power system; the optimized evaluation index is determined and evaluated. The present invention adopts the strategy of using heat to determine electricity and uses the improved whale algorithm to solve the micro-grid model of combined cooling, heating and power supply. In the initial stage, the chaotic initialization operation is performed to improve the search ability, and the mutation operation introduced in the round-up stage can be faster. The global optimal value can be found accurately, and the purpose of quickly finding the optimal solution for the optimal operation of the combined cooling, heating and power system is realized.
