基于双层博弈理论的差异化乡村多微能网协同功率调度策略
Bi-Level Game Theory-Based Collaborative Power Dispatch Strategy for Heterogeneous Rural Multi-Microgrids
随着乡村可再生能源大规模接入,这类能源受自然条件影响具有显著的随机性、间歇性,不仅会导致电网功率波动加剧,还可能引发接入点电压升高或降低、频率超限等问题,影响用电设备正常工作以及电网的整体电能质量。针对上述问题,提出了一种基于Stackelberg双层博弈理论的差异化多微能网协同功率调度策略。首先,构建了包含高渗透率和中等渗透率两类乡村微能网的互补模型,通过差异化配置燃气轮机装机容量实现电源结构优化。其次,设计了包含可平移负荷、可转移负荷与可削减负荷的柔性负荷分级调节机制,以提升系统灵活性,为平抑功率波动提供了多层次调节手段。最后,建立了基于Stackelberg双层博弈的“局部自治-网间互济”的调度策略,RT-LAB仿真实验表明,相比单一负荷调节策略,所提策略可再生能源出力的峰谷差降低5.6 %。相比无网间互济策略,系统运行成本降低22 %。该方法为乡村振兴战略下的能源体系建设提供了有效方案。
With the large-scale integration of rural renewable energy, such energy sources, influenced by natural conditions, exhibit significant randomness and intermittency. This not only exacerbates power grid fluctuations but may also triggers issues like voltage rise or drop at access points, frequency exceeding limits, and other problems, affecting the normal operation of electrical equipment and the overall power quality of the grid. To address the above challenges, a differentiated coordinated power dispatch strategy for multi-microgrids based on Stackelberg bi-level game theory is proposed.Firstly, a complementary model comprising two types of rural multi-microgrids—high-penetration and medium-penetration—is constructed. By differentially configuring the installed capacity of gas turbines, the power source structure is optimized. Secondly, a hierarchical flexible load regulation mechanism is designed, incorporating shiftable loads, transferable loads, and reducible loads, to enhance system flexibility and provide multi-level regulation means for mitigating power fluctuations. Finally, a "local autonomy-inter-grid mutual support" dispatch strategy is established based on the Stackelberg bi-level game. RT-LAB simulation experiments show that, compared to a single load regulation strategy, the proposed strategy reduces the peak-to-valley difference of renewable energy output by 5.6 %. Compared to a no-inter-grid mutual support strategy, the system operation cost is reduced by 22%. This method provides an effective solution for energy system development under the rural revitalization strategy.
