基于合作博弈的风水火联合运营研究

近年来,电力需求增速有所放缓,导致可再生能源弃用问题较为严重,为可再生能源出让发电空间的火电企业生存问题亦日益凸显,解决这一系列矛盾迫在眉睫。论文提出了市场化情况下风水火联合运营模式,火电将发电空间转让给风电、水电并提供辅助服务以实现联盟效益最大化,基于合作博弈理论对联盟效益进行再分配以实现个体效用最大化。通过算例分析了不同联盟模式下的联盟经济效益和环境效益以及不同分配策略下风水火联合运营各参与人的分配效用,并依据MDP指标分析了不同分配策略对联盟参与人的吸引力。结果表明风水火三方联合运营可以实现联盟经济效益和环境效益最大化,选用夏普利值分配策略作为联盟效用分配方案最为合理。风水火联合运营可有效解决弃风弃水问题并改善火电企业运营状况,保障了电力结构低碳化平稳过渡,为促进火电与可再生能源合作提供了理论依据。

Research on Wind-hydro-thermal Power Joint Operation Based on Cooperative Game Theory

In recent years, the growth rate of electricity demand has slowed down, resulting in the problem of serious renewable energy abandoning. Thus, the survival problem of thermal power enterprises which transfer generation rights to renewable energy is becoming more and more prominent. So it is imminent to solve this series of contradictions. This paper presents the joint operation mode of wind power and hydropower and thermal power. In order to maximize the alliance benefit, the thermal power transfers the generation rights to the wind power and hydropower, and provides auxiliary services. Then, maximize the individual benefit by reallocating the alliance benefit. It is analyzed and compared in this paper that the economic and environmental benefits of alliance under different modes and the distribution utility of the participants in the joint operation under different allocation strategies. And based on the MDP indicator, the attractiveness of different allocation strategies to participants is analyzed. The results show that wind-hydro-thermal power joint operation can maximize economic and environmental benefits of the alliance and that shapley value is the most reasonable allocation strategy. Wind-hydro-thermal power joint operation can effectively solve the problem of renewable energy abandoning and thermal power management, guarantee the smooth transition of low carbonization of power system, and provide a theoretical basis for the cooperation between thermal power and renewable energy.
