Problems solved by technology

[0004] Although the access of new energy to the power distribution system has a certain significance in reducing emissions, it cannot meet all the energy needs of users. In addition, previous studies on the bidding of the Cournot game have constructed the relationship between power generators and users through the relationship between supply and demand. The game relationship between the supply and demand curves follows economic principles, and the monotonicity remains unchanged. This method cannot effectively save user costs, nor can it improve energy utilization.

Abstract

The invention discloses a method and a system for balancing a comprehensive energy market in an industrial park. The method mainly comprises the following steps: constructing a peak clipping and pricing compensation model based on an industrial park comprehensive energy market; secondly, after the research on the cournot game of the power market in the past is referenced, establishing a user benefit model and an interactive game mechanism for multiple subjects in the industrial park, considering double-side thermoelectric coupling of a system side and a user side of the park, incorporating thedouble-side thermoelectric coupling into a game target between users, and constructing a regularized Nikaido-Isoda function and using a distributed relaxation algorithm to solve it optimally, and obtaining the equilibrium point of the integrated energy market. By applying the method and the system, not only can the requirements of all users in the industrial park be met, but also the user cost iseffectively saved, and the utilization rate of energy is improved.

Description

technical field [0001] The invention relates to the technical field of multi-energy power generation systems, in particular to a method and system for balancing the comprehensive energy market in industrial parks. Background technique [0002] Electric utilities face particular challenges in meeting changing consumer load demands. There are at least two related reasons for these challenges. First, electricity demand can fluctuate significantly from day to day or hour to hour, making it difficult for utilities to ensure they have enough capacity to meet demand. These fluctuations in energy demand can be due to daily cyclical energy application patterns (such as peaks in the afternoon), or due to unexpected changes in the balance of energy supply and demand, such as a generator connected to the grid stops working, Large energy consumers go online or offline, or there is a failure in the distribution system. [0003] A second element of the challenge facing utilities is that...
