基于主从博弈的配电网–多农村生产园区优化运行策略

Stackelberg Game-based Optimal Operation Strategy for Distribution Networks and Multiple Rural Production Parks

  • 摘要: 针对考虑需求响应和共享储能的配电网–农村生产园区电力系统优化问题,提出了一种基于主从博弈的双层优化调度策略。首先,通过分析包括分布式光伏、冷热电需求响应和共享储能等多种资源的协同运行特性,建立了配电网–多农村生产园区的优化模型,揭示了不同资源间的交互耦合及对系统经济性和稳定性的作用。接着,基于资源协调优化需求并考虑多方利益平衡,提出了配电网与多农村生产园区之间的主从博弈优化调度方法。最后,在Matlab/Simulink平台上建立了多农村生产园区的电力调度仿真模型,对所提优化策略在提升系统经济效益、降低峰谷差、提高可再生能源消纳能力等方面的效果进行了验证。仿真结果表明,与对比方案相比,所提优化方案运行的经济效益提高27.9%,高峰时段的电力购入成本减少2907元,显著提升了整体系统的经济性和可持续性。

     

    Abstract: This paper proposes a bi-level optimization scheduling strategy based on Stackelberg game theory for the distribution network–rural production park power system, considering demand response and shared energy storage. First, by analyzing the coordinated operation characteristics of distributed photovoltaics, cooling–heating–electrical demand response, and shared energy storage, an optimization model for the distribution network interconnected with multiple rural production parks is established, revealing the interactive coupling among heterogeneous resources and their impacts on system economics and operational stability. A Stackelberg game-based scheduling framework is then developed between the distribution network and multiple rural production parks to coordinate resources and balance multi-stakeholder interests. Finally, a power dispatch simulation model is implemented on the MATLAB/Simulink platform to validate the proposed strategy in terms of economic performance, peak-to-valley load reduction, and renewable energy integration. Simulation results demonstrate that, compared with benchmark schemes, the proposed strategy improves operational economic benefit by 27.9% and reduces peak-period power purchase costs by 2,907 CNY, significantly enhancing overall system economics and sustainability.
