Multi-objective optimization method of cold-heat-electricity comprehensive energy system

Abstract

The invention belongs to the technical field of comprehensive energy systems, and particularly relates to a multi-objective optimization method of a cold-heat-electricity comprehensive energy system,which comprises the following steps: S1, establishing a model of the cold-heat-electricity comprehensive energy system; s2, establishing a multi-objective optimization model; and S3, solving the multi-objective optimization model. In the aspect of model topology, rich model topology and numerous model constraints are considered, and mutual complementation and coordinated complementation of multiple types of heterogeneous energy flows can be realized; besides, theoretical analysis is performed on the stability of the comprehensive energy system, and the comprehensive energy system is differentfrom the coupling relationship and the working mechanism of each independent energy production system, so that the stability of the system is 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 is greatly determined, and the output stability control of the system can be realized.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy systems, and in particular relates to a multi-objective optimization method for a cold-heat-electric comprehensive energy system. Background technique [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 it more difficult to coordinate the system output.
