Regional distributed energy network design and optimization method based on master-slave game

Abstract

The invention relates to a regional distributed energy network design and optimization method based on a master-slave game, and the method comprises the following steps: S1, building an energy stationutility function at an energy station side according to a distributed energy station energy selling income function and a distributed energy station cost function; S2, establishing a user satisfaction function at a user side, and establishing a user side utility function according to the user satisfaction function; s3, establishing a master-slave game model of the regional distributed energy stations and the energy users according to the energy station utility function and the user side utility function; s4, setting an operation constraint condition of the energy internet; and S5, performinginteractive game optimization on the master-slave game model in combination with an operation constraint condition to obtain the optimal energy price of the energy station. Compared with the prior art, the method has the advantages that the cold load and the heat load in the distributed energy system are fully considered, the complete time periods among the participants are selected for gaming, the type selection investment of the function side equipment is fully considered, and the gaming equilibrium solution is more accurate.

Description

technical field [0001] The invention relates to a method for designing and optimizing a distributed energy network, in particular to a method for designing and optimizing a regional distributed energy network based on a master-slave game. Background technique [0002] As the scale of decision-making subjects participating in the operation of the regional distributed energy Internet increases sharply compared with traditional power grids, when each decision-making subject chooses an action in the regional distributed energy Internet, it must consider the impact of the actions of other decision-making subjects on its own interests , so how to coordinate the relationship among decision-making subjects in the regional distributed energy Internet, balance and optimize the interests of all parties is a very challenging problem. In this context, the game theory that can consider the interaction of multiple decision-making subjects and the coordination and balance of multiple object...

AI Technical Summary

Problems solved by technology

[0003] The study found that the game of electric energy in the regional distributed energy system has a relatively mature game model and has formed certain theoretical results, but there are few studies on the game of cooling and heating loads in the regional distributed energy system; and in the existing In some studies, the game between participants often selects short-term energy supply and demand as the research object, and does not fully consider the game between participants in a complete time period; in the game, the selection of equipment on the energy supply side, investment , and the connection between external energy networks, etc.
