Multi-main-body cooperation optimization operation and cost benefit distribution method for comprehensive energy system

Abstract

The invention provides a multi-main-body cooperation optimization operation and cost benefit distribution method for comprehensive energy system, and relates to the technical field of integrated energy system economic operation. The method is based on an energy hub concept, and comprises: providing a multi-energy hub cooperative operation mode, and establishing a multi-energy hub economic operation model containing renewable energy power generation and power storage equipment; and analyzing a cost benefit calculation method of each subject participating in cooperation, and distributing the increased cost and benefit for executing a cooperative economic operation strategy on each subject based on a cooperative game theory. According to the method provided by the invention, the characteristics of multi-energy complementation at the energy supply side and load transfer at the energy utilization side of the comprehensive energy system are fully considered. The multi-energy hub optimizationoperation model has economy and effectiveness, the development requirement of a green and low-carbon energy system is met, the cost and benefits of all subjects participating in cooperation are distributed based on a Shapley value method, and a splitting tendency index is designed to verify the enthusiasm of the method for maintaining cooperation stability.

Description

technical field [0001] The invention relates to the technical field of economic operation of an integrated energy system, in particular to a multi-agent cooperative optimization operation and cost-benefit allocation method of an integrated energy system. Background technique [0002] In recent years, with the rapid development of society and economy, the large-scale use of fossil energy has led to a series of problems such as the depletion of traditional energy sources, environmental pollution, and global climate deterioration. Therefore, research on clean and efficient sustainable energy systems has become an inevitable choice to solve problems. The energy interconnection form of multi-energy complementarity improves energy availability by means of the complementary conversion between traditional fossil energy and renewable energy, and makes up for the shortcomings of systems that are planned and operated independently for each energy source; at the same time, the developme...

Problems solved by technology

[0003] Existing studies have actively explored the optimal operation of energy hubs in integrated energy systems that include demand response. Usually, the modeling of a single energy hub is considered, and there is little analysis of the cooperation form of the energy hub and the direction of energy flow within the hub; at the same time, for energy The environmental problems brought about by the system, the development of clean energy and the reduction of greenhouse gas emissions are necessary forms for the development of future energy systems, and there are few studies considering the impact of other greenhouse gases on multi-energy optimization; existing studies have shown that although energy storage devices are renewable The access to energy has played an important role, but it still has the disadvantages of emissions; a large number of electric vehicles and energy storage equipment are connected to the grid, which is the main body of good demand response implementation, and can play a role in reducing peak power consumption
