中文摘要:采用Cournot古诺寡头博弈理论来确定在孤岛模式下负荷聚合商内发电单元与用户之间的纳什均衡。通过此纳什均衡，确定资源提供者和用户之间的理想能量分配比例。为了最大化系统的整体效益并保持负荷聚合商的稳定性，引入了一种基于一致性理论的分布式控制方法。这种方法使每个产消者和发电单元根据总体需求负荷调整其能量输出。利用纳什均衡确定的最优资源分配比例，有效地消除了负荷聚合商内所有节点单元的稳态频率偏差，从而保证了用户的能源质量标准。仿真结果验证了控制策略在实现所提研究目标方面的有效性。

Abstract:This study employs Cournot oligopoly game theory to determine the Nash equilibrium among power generation unit and users within load aggregators under an independent mode. Through this Nash equilibrium， we determine the optimal energy allocation ratio between resource providers and users. To maximize the overall efficiency of the system and maintain the stability of load aggregators， the study introduces a distributed control method based on consistency theory. This method enables each product-consumer and generator to adjust its energy output based on the overall demand load. By leveraging the optimal resource allocation ratio derived by the Nash equilibrium， this paper effectively eliminates the steady-state frequency deviation of all units within load aggregators， thereby ensuring the energy quality standards for users. Simulation results validate the effectiveness of the proposed control strategy in achieving the research objectives.
