Regional comprehensive energy system optimization operation method based on repeated game model

Abstract

The invention discloses a regional comprehensive energy system optimization operation method based on a repeated game model. The method comprises the steps of firstly, performing steady-state modelingand power flow analysis on a power distribution network, a gas distribution network and a micro-energy network in a regional comprehensive energy system; then, considering the interaction influence between a power link and an energy coupling link in the regional comprehensive energy system; using a micro-energy network and a power distribution network as game participants; constructing a repetitive game optimization model of the regional comprehensive energy system by taking the daily operation cost of the micro-energy network and the comprehensive satisfaction of the power distribution network as respective utility functions, and solving the repetitive game optimization model by adopting an adaptive mutation particle swarm algorithm to obtain a game equilibrium optimization result of theregional comprehensive energy system; and finally, verifying the correctness and effectiveness of the regional comprehensive energy system optimization operation method based on the repeated game model. The method can give full play to the active regulation and control effect of the power distribution network, gives consideration to the benefits of the micro-energy network and the power distribution network, and achieves the cooperative economic optimization operation of the regional integrated energy system.

Description

technical field

[0001] The invention relates to a method for optimizing operation of a regional comprehensive energy system. In particular, it relates to a method for optimizing the operation of a regional comprehensive energy system based on a repeated game model. Background technique

[0002] With the deep adjustment of the world's energy pattern and the increasing global environmental pollution, in order to deal with a series of challenges in the field of energy technology, the integrated energy system (IES) came into being. IES can be regarded as a natural extension of microgrid, which is mainly composed of energy supply network, energy conversion link, energy storage link, comprehensive energy supply unit and end users. On the one hand, through the overall scheduling and collaborative optimization of multiple energy sources, it can give full play to the complementary advantages of distributed energy and improve the utilization rate of renewable energy; on the other han...
