摘要: 针对开放电力市场环境中多主体电能交易机制下系统的经济调度问题,提出了一种基于合作博弈理论的用户侧分布式储能鲁棒博弈优化调度方法。该方法旨在协调配电网与用户之间的能量交互,通过寻找博弈模型的均衡点来制定最优的用户侧储能调度策略,提高系统的新能源消纳水平和经济效益。其次,为减少系统中源荷功率不确定性对实际调度运行过程中系统经济性的影响,采用鲁棒优化理论对不确定性因素进行处理。最后,通过实例分析验证了所提优化调度方法对提高系统光伏消纳水平、降低市场主体运行成本的有效性。

Abstract: Aiming at the economic scheduling problem of the system under multi-agent energy trading mechanism in open electricity market, this paper proposes a robust game optimization scheduling method for user-side distributed energy storage based on cooperative game theory. The purpose of this method is to coordinate the energy interaction between distribution network and users. By finding the equilibrium point of the game model, the optimal user-side energy storage scheduling strategy is formulated, so as to improve the new energy consumption level and economic benefits of the system. Secondly, in order to reduce the influence of source and load uncertainty on the system economy in the actual dispatching operation process, robust optimization theory is used to deal with the uncertain factors. Finally, an example is given to verify the effectiveness of the proposed optimal scheduling method to improve the photovoltaic energy consumption level and reduce the operation cost of market entity.
