Abstract

With the increasing penetration of distributed energy in the distribution network, it is urgent to study how to ensure the stable and reliable operation of the power grid under fault conditions. To solve this problem, this study proposes a method for partitioning distribution network islands and reconstructing faults considering the Conditional Value at Risk (CVaR). This method aims to enhance the resilience of the distribution network and the recovery capability of critical loads. Initially, a partitioning model for distribution network islands based on depth-first and breadth-first search algorithms was constructed. Building upon this partitioning, a fault reconstruction method for distribution networks that considers CVaR was developed. This method utilizes CVaR theory to transform costs and quantifies the risk that the uncertainty of distributed energy resources poses to distribution network reconstruction strategies. Finally, the effectiveness of the proposed method is demonstrated using an improved IEEE 33-node system, generating typical fault scenarios.
基于风险条件值的主动配电网岛屿分区和故障恢复重构
随着分布式能源在配电网中的渗透率越来越高,研究如何确保电网在故障条件下稳定可靠地运行已迫在眉睫。为解决这一问题,本研究提出了一种考虑风险条件值(CVaR)的配电网孤岛划分和故障重构方法。该方法旨在提高配电网络的恢复能力和关键负载的恢复能力。最初,基于深度优先和广度优先搜索算法构建了配电网岛分区模型。在此分区基础上,开发了一种考虑 CVaR 的配电网络故障重构方法。该方法利用 CVaR 理论转换成本,并量化了分布式能源资源的不确定性给配电网络重建策略带来的风险。最后,利用改进的 IEEE 33 节点系统,生成典型的故障场景,展示了所提方法的有效性。
