本公开涉及一种基于分布鲁棒优化的微电网调度方法,其中,该方法通过将基于多离散场景的DRO方法应用至包含天然气压力能发电设备以及集中充电站的微电网系统,以微电网系统运行成本最低和联络线功率波动最小共同作为调度优化目标,并考虑天然气压力能发电、光伏发电和负荷的不确定性,基于多离散场景的DRO方法建立两阶段DRO模型,并求解两阶段DRO模型得到满足上述两个调度优化目标的调度计划,从而微电网系统执行该调度计划能够有效降低微电网系统的整体运行成本并抑制联络线功率波动,且鲁棒性较高。此外,在构建第一目标函数时充分考虑了天然气压力能弃用和光伏发电弃用的情况,保证了微电网系统调度效果最优。

    The invention relates to a micro-grid dispatching method based on distributed robust optimization, and the method comprises the steps: applying a DRO method based on multiple discrete scenes to a micro-grid system which comprises natural gas pressure energy power generation equipment and a centralized charging station; the minimum operation cost of a micro-grid system and the minimum power fluctuation of a connecting line are jointly used as scheduling optimization targets, uncertainty of natural gas pressure energy power generation, photovoltaic power generation and loads is considered, a two-stage DRO model is established based on a DRO method of multiple discrete scenes, the two-stage DRO model is solved, and a scheduling plan meeting the two scheduling optimization targets is obtained. Therefore, when the micro-grid system executes the scheduling plan, the overall operation cost of the micro-grid system can be effectively reduced, the power fluctuation of the tie line can be inhibited, and the robustness is high. In addition, when the first objective function is constructed, the situations of natural gas pressure energy abandoning and photovoltaic power generation abandoning are fully considered, and it is guaranteed that the dispatching effect of the micro-grid system is optimal.
