摘要/Abstract

摘要： 在“双碳”背景下,为有效提高综合能源系统（IES）的能源利用率,减少碳排放量,同时提升系统运行的灵活性,提出一种基于合作博弈的IES优化运行模型。首先构建IES框架,针对电转气（P2G）、碳捕集、燃气轮机、热储能等设备进行建模;其次考虑系统内各主体之间存在协同合作的可能,将系统内各运营主体分为三方构建合作联盟,阐述能源互补提高整体收益的原理;最后建立基于合作博弈的IES协同优化调度模型,利用Shapley值法对合作剩余按贡献进行分配。该文通过内蒙古地区某综合能源系统实例仿真分析,验证了所提出的策略能有效减少各合作主体的运行成本及合作联盟的运行总成本,促进联盟内多主体开展合作,同时有效提升系统内风电消纳能力,减少系统碳排放量,可为电力系统低碳经济调度提供理论参考。

Abstract: Under the background of " peak carbon dioxide emissions" and " carbon neutrality ", in order to effectively improve the energy efficiency of integrated energy system（IES）, reduce carbon emissions and improve the flexibility of system operation, an optimal operation model of IES based on cooperative game is proposed. The first step is to build an IES framework and a model for the devices of P2G, carbon capture, gas turbine and thermal energy storage. Then, divide the operation subjects in the system into three parts and construct a cooperative alliance within them considering the possibility of their coordination, and illustrate how to increase the overall interests through energy complementarity. Finally, set up an IES cooperative optimal operation model, and use Shapley value to distribute the cooperative surplus according to their contributions. By the simulation analysis of an IES in Inner Mongolia region, this paper verified that the proposed strategy can evidently reduce the operating cost of the cooperative subjects and the overall cost of the cooperative alliance. It prompts the cooperation within the subjects in the alliance, improves the wind power accommodation capacity of the system, and reduces the carbon emission, prorides theoretical support for the operation of the low-carbon economy of the power systems.
