Multi-objective optimization method for cooling-heating-electricity integrated energy system

Abstract

The invention belongs to the technical field of integrated energy systems, and in particular relates to a multi-objective optimization method of a cold-heat-electric integrated energy system. The multi-objective optimization method comprises the following steps: S1. Establish a model of a cold-heat-electric integrated energy system; S2 . Establish a multi-objective optimization model; S3. Solve the multi-objective optimization model. In terms of model topology, the present invention considers abundant model topologies and numerous model constraints, and can realize the mutual complementation and coordination and complementation of multiple types of heterogeneous energy flows; The system is different from the coupling relationship and working mechanism of the individual energy production systems, which makes the system stability more difficult to coordinate, and the input and output relationships are difficult to match. By analyzing the stability of the system, the stability domain of the system will be greatly determined, and the stable output of the system can be controlled.

technical field [0001] The invention belongs to the technical field of integrated energy systems, and in particular relates to a multi-objective optimization method of a cold-heat-electric integrated energy system. Background technique [0002] The integrated energy system couples multiple types of energy production terminals, which can realize the coordination and complementation of multiple types of energy sources, but the coupling of multiple types of heterogeneous energy flows also brings about the uncertainty of multiple types of energy output and the fuzzy matching of input and output. . Especially when multiple types of loads in an integrated energy system are independent of each other and accompanied by randomness, although multiple energy sources can achieve multi-energy complementarity, it also makes the system output more difficult to coordinate. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides a multi-objective op...

[0002] The integrated energy system couples multiple types of energy production terminals, which can realize the mutual coordination and supplementation of multiple energy sources, but the coupling of multiple types of heterogeneous energy flows also brings uncertainty in the output of multiple types of energy and the fuzzy matching between input and output.

Especially in the case where multiple types of loads in the integrated energy system are independent of each other and accompanied by randomness, although multiple energy sources can achieve multi-energy complementarity, it also makes the system output more difficult to coordinate
