Abstract

The present application discloses a day-ahead scheduling method and a related device for an integrated energy system, wherein the method includes: constructing an output model and a daily cost model for day-ahead scheduling according to the operation of the integrated energy park in the integrated energy system; based on the output model and the daily cost model; The daily cost model builds a two-layer optimal scheduling model consisting of an upper-layer model and a lower-layer model; based on the non-cooperative game theory, the iterative optimization of the two-layer optimal scheduling model is carried out for the N sub-areas of the comprehensive energy park, and the target corresponding to each sub-area is determined. Operation strategy, the target operation strategy includes the target output strategy and the target thermoelectric ratio adjustment strategy; according to all the operation strategies, the corresponding operation scheduling of the comprehensive energy park is carried out, which solves the problem that the comprehensive energy park is not comprehensively considered in the existing scheduling, and energy allocation occurs. Unbalanced, resulting in technical problems of low energy utilization.

Description

technical field [0001] The present application relates to the technical field of power dispatching, and in particular, to a day-ahead dispatching method and related devices of an integrated energy system. Background technique [0002] With the growth of energy demand and the acceleration of urbanization, the contradiction between energy demand and environmental resources has become increasingly prominent. In such a large environment, the integrated energy system came into being. [0003] Integrated energy system operation refers to the use of advanced physical information technology and innovative management mode in a certain area (ie, integrated energy park) to integrate coal, oil, natural gas, electric energy, thermal energy and other energy sources in the area to realize the interconnection between various energy subsystems. Coordinated planning and optimized operation. The basic requirement of an integrated energy system is to effectively improve energy utilization eff...
