Multi-energy joint optimal scheduling mechanism based on cooperative game considering transmission section limitation

Abstract

The construction of power grid infrastructure lags behind the growth rate of installed power capacity, which makes it difficult to deliver clean energy in some areas, and multiple clean energy sources seize power generation channels. Taking the power system in a certain area of Zhejiang Province as the research object, the day-ahead scheduling mechanism suitable for the joint optimization of multiple power sources under the limitation of transmission section is discussed, and an improved comprehensive power generation benefit evaluation system is established. Firstly, the coefficient matrix of objective function is defined, and a mixed linear integer programming model with variable objective function is established. Then, the transmission channel load rate and transmission power smoothness are defined as the social benefits of power generation in this area. Finally, the optimal cooperation strategy and unit output combination are determined by changing the objective function coefficient matrix. The analysis of an example shows that the comprehensive power generation benefit can be optimized by adopting the strategy of the big alliance cooperative game.
