为应对用电需求快速增长背景下配电网扩展规划日益凸显的重要性,提出了一种基于可靠性增量的快速评估方法。首先,该方法将扩展后配电网的可靠性指标拆分为现状配电网的可靠性指标与扩展部分的可靠性增量,通过复用现有可靠性指标并仅计算增量部分,显著降低了计算量;其次,构建了一种增量相关故障状态识别方法,筛选与可靠性增量相关的故障状态并剔除无关状态,进一步提升评估效率;最后,基于改进的RBTS Bus6 Feeder4算例验证表明,该方法可显著提高配电网扩展规划的可靠性评估效率。
To address the growing importance of distribution network expansion planning amid rapidly increasing electricity demand, this study proposes a rapid assessment method based on reliability increments. First, the reliability metrics of the expanded distribution network are decomposed into the reliability metrics of the existing network and the reliability increment from the expansion. By reusing existing reliability metrics and computing only the increment, this method significantly reduces computational complexity. Second, an incremental-relevant fault state identification technique is developed to screen fault states impacting reliability increments while filtering out irrelevant states, further enhancing evaluation efficiency. Finally, validation based on a modified RBTS Bus6 Feeder4 test case demonstrates that the proposed method markedly improves the efficiency of reliability assessment for the distribution network expansion planning.
