Coordinated Configuration Method of Cyber and Physical Equipment in Distribution Networks Based on Interval Robust Control

为提高配电网消纳高比例分布式电源的经济性,充分利用一次侧储能和二次侧主动调控的灵活性,该文提出一种基于区间鲁棒控制的配电信息物理双层设备协调配置方法。首先,建立分布式电源控制选点与储能配置的协调优化综合经济性模型,而后,考虑源荷不确定性,以电压越限风险水平为约束,建立配电网区间鲁棒优化运行模型,形成双层优化模型;最后,给出基于差分进化算法的求解流程,并以IEEE-33节点配电系统为例验证模型的有效性,同时仿真分析不同可接受风险水平和设备价格对配置的影响,为高渗透配电网的经济消纳方案提供有益的参考。

In order to achieve the scenario of high-proportion distributed generations being consumed in distribution networks,this paper proposed a coordinated configuration method of cyber and physical equipment in distribution networks based on interval robust control,making full use of the flexibility of energy storage in the primary side and the active regulation in the secondary side.First,a comprehensive economic configuration model of the distributed generation control and energy storage was established.Then,considering the uncertainty of sources and loads,a robust optimal operation model was established with the constraint of the risk level of voltage exceeding.And a two-layer optimization model was built.The solution was based on the differential evolution algorithm.Finally,the effectiveness of the model was verified by taking the IEEE-33 node power distribution system as an example.Simultaneously,the impact analysis of different acceptable risk levels and equipment prices on the configuration was given.The research results could provide a useful reference for the economic consumption of distributed generations in the distribution networks.
