摘要(Abstract)：

传统配电网拓扑选择常根据历史经验，多以可靠性和经济性为决策依据，评价维度单一，不适用于含多种分布式能源的新型配电网。为此，提出一种适应“水光充储”接入的配电网拓扑结构评价方法。在传统可靠性和经济性评价指标基础上，新增拓扑连接方式、可开放容量以及拓扑灵活性，建立新型配电网拓扑结构多属性评价指标体系。其中可开放容量指标可反应多种分布式资源的时序波动性对配电网结构的影响，拓扑灵活性指标反应配电网应对负荷增长和故障恢复的能力。最后，采用熵权法和层次分析法对多种配电网场景下各指标进行计算，所得结果可指导新型配电网拓扑结构的合理选择。
The topology selection of traditional distribution networks is often based on historical experience, with reliability and economy as the main decision-making criteria. However, this approach is limited by a single evaluation dimension and is not suitable for new-type distribution networks with multiple types of distributed energy. To address this, a new evaluation method for distribution network topology is proposed, which adapts to the integration of “hydropower-PV-charging-storage”. In addition to traditional reliability and economy evaluation indicators, new factors such as topology connection methods, available capacity, and topology flexibility are introduced to establish a multi-attribute evaluation system for new-type distribution network topologies. The available capacity indicator reflects the impact of the time-series volatility of distributed resources on the distribution network structure, while the topology flexibility indicator reflects the network's ability to respond to load growth and fault recovery. Finally, the entropy weight method and analytic hierarchy process(AHP) are employed to calculate the indicators under various distribution network scenarios. The results can guide the reasonable topology selection of new-type distribution network.
