台风期间考虑配电终端功能可用性的配电网重构方法

Distribution Network Reconfiguration Method Considering Availability of Distribution Terminal Functions During Typhoon Disaster

近年来,包括地震、台风、山火等事件在内的极端灾害,给城市配电网的电气和通信控制设备造成了极大的破坏。为此,考虑台风灾害冲击,提出了一种考虑配电终端信息物理功能短时可用特性的配电网受灾和恢复过程仿真方法,用于改进配电网韧性量化评估结果。分析了灾害中储能支撑配电终端信息物理功能短时存续的能力,建立了考虑配电终端可用性的多阶段配电网拓扑重构流程,设计了配电网韧性评估指标和恢复过程仿真算法。针对IEEE 33节点系统算例的研究表明,灾害下配电终端信息物理功能削弱将造成配电网停电损失扩大、韧性水平下降。实验结果说明了所提方法的合理性和有效性。

In recent years,extreme disasters such as earthquakes,typhoons and mountain fires have caused significant damage to the electrical and communication control equipment for urban distribution networks.To this end,considering the impact of typhoon disaster,a simulation method is proposed for the disaster and recovery process of the distribution network considering the shortterm availability of the distribution terminal cyber-physical function,to improve the quantified resilience assessment result of the distribution network.The ability of energy storage during the typhoon disaster to support the short-term survival of the cyberphysical functions of distribution terminals is analyzed.A multi-stage reconfiguration process of the distribution network considering the distribution terminal availability is established.The resilience assessment indices and recovery process simulation algorithms are designed.Research on the IEEE 33-bus system example shows that weakening the cyber-physical function of the distribution terminal during typhoon disasters will increase the power outage loss and decrease the resilience level.Experimental results verify the rationality and effectiveness of the proposed method.
