Abstract

The invention discloses a day-ahead scheduling method for an integrated energy system and a related device, and the method comprises the steps: constructing an output model and a day cost model for day-ahead scheduling according to the operation condition of an integrated energy park in the integrated energy system; based on the output model and the daily cost model, constructing a double-layer optimization scheduling model composed of an upper-layer model and a lower-layer model; based on a non-cooperative game theory, performing iterative optimization of a double-layer optimization scheduling model on N partitions of the comprehensive energy park, determining a target operation strategy corresponding to each partition, and the target operation strategies comprising a target output strategy and a target thermoelectric ratio adjustment strategy; according to all the operation strategies, performing corresponding operation scheduling on the comprehensive energy park. The technical problems that comprehensive consideration is not carried out on the comprehensive energy park during existing scheduling, energy distribution is unbalanced, and the energy utilization rate is not high aresolved.

Description

technical field [0001] The present application relates to the technical field of electric power dispatching, 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 big 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 models in a certain area (i.e., integrated energy park) to integrate coal, oil, natural gas, electric energy, thermal energy and other energy sources in the area to realize the integration of various energy subsystems. Coordinated planning and optimized operation. The basic requirement of an integrated energy system is to effectively improve energy utilization effici...
