考虑直流线路和换流器故障的交直流配电网弹性分析
Resilience Analysis of AC/DC Distribution Network considering DC Line and Converter Faults
摘要: 随着用户对直流配电网需求的日益增加，交直流混合配电网可能成为未来配电网发展的重要方向之一。为提升交直流配电网面对极端攻击事件的抵御、适应、恢复能力，本文建立了考虑直流线路和换流器故障的防御–攻击–防御三层弹性规划模型。模型以加固元件和分布式能源预置为规划措施，在考虑系统受到最严重攻击情况下，实现了综合费用最小和失负荷最小的目标。本文以列与约束生成算法为求解方法，构建22节点系统进行算例分析，验证了本文方法的有效性。
Abstract: With the increasing demand for DC distribution network, AC-DC hybrid topology may become an important direction of future distribution network development. In order to improve the ability of resisting, adapting and recovering in the face of extreme attack events, a tri-level resilience programming model, which takes the form of defense-attack-defense model, is established in this paper. Also, the fault of DC lines and converters are considered. The model takes the components hardening and distributed energy presetting as the planning measures. Considering the most serious attack on the distribution network, it finally achieves the goal of minimum comprehensive cost and minimum load loss. In this paper, the column and constraint generation algorithm is used as the solution method, and the effectiveness of this method is verified by the example analysis.
