摘要:
      能源互联网中存在多能源交易及多市场主体,建立合理的多市场主体成本收益模型是亟待解决的难题之一。本文所研究的主要针对城镇或区域级能源互联网,其交易场景为电网公司、热电厂和大用户三个市场交易主体,其中的热电厂作为电热能源耦合元件,采用以热定电的典型运行模式供能并报价;电网按过网服务费形式报价;大用户根据前两者报价,选择与热电厂或电网公司交易热能与电能。在该交易机制下建立了计及热电耦合的三方非合作博弈收益模型,证明了该博弈模型存在纳什均衡,并提出了相应求解方法。通过算例分析,得出在电热多能源交易系统中的纳什均衡范围,解释了纳什均衡的物理意义,并分析了各主体收益参数对该博弈论纳什均衡分布的影响。
Abstract:
      Energy internet involves multi-energy transactions and multiple market entities. It is one of the most urgent problems to establish a reasonable cost benefit model for multiple market entities. This paper mainly focuses on urban or regional energy internet, in which the trading scenario includes the following three entities: power grid companies, thermal power plants and large users. Thermal power plants, as the coupling component of electric and thermal energy, adopt the typical operation mode of “fixing heat based on power” to supply energy and offer prices. The power grid offers in the form of service fees through the network usage. The large users choose to trade thermal and electric energy with thermal power plants or power grid companies according to the above two quotations. Under this trading mechanism, a three-entity non-cooperative game income model considering thermoelectric coupling is established. The existence of the Nash equilibrium of the game model is proved, and the corresponding solution method is proposed. The Nash equilibrium range in the thermoelectric multi-energy transaction system is obtained through the analysis of case studies. The physical meaning of Nash equilibrium is explained, and the influence of the parameters of the income model for each market entity on the Nash equilibrium distribution of the game theory is analyzed.
