基于协同恢复策略的主动电网供电恢复策略研究

Research on a Resilience Assessment Method of Distribution Network Accident Risk

针对目前主动配电网恢复能力有限缺陷,提出了一种基于协调恢复策略的主动配电网供电恢复模型。基于SOP原理,在理论层面充分考虑SOP位置和容量对配电网的影响。在多个SOP协同运行基础上,建立了含约束的多SOP供电恢复多目标优化函数。实验阶段,以改进的IEEE33总线系统为例,验证所提模型有效性。结果表明,与现有方法相比,所提方法能有效提高主动配电网在故障情况下的快速恢复能力。仿真结果进一步验证了所提模型对提高主动配电网恢复能力具有一定借鉴作用。

A coordinated recovery strategy based active distribution network power supply recovery model is proposed to address the limited recovery capability of current active distribution networks.Based on the principle of SOP,the influence of SOP location and capacity on distribution network is fully considered.Based on the cooperative operation of multiple SOPs,a constrained multi-objective optimization function for power supply restoration of multiple SOP is established.In the experimental stage,the improved ieee33 bus system is taken as an example to verify the effectiveness of the proposed model.The results show that compared with the existing methods,the proposed method can effectively improve the rapid recovery ability of active distribution network in the case of fault.The simulation results further verify that the proposed model can be used for reference to improve the restoration ability of active distribution network.
