    摘要:

    自然灾害的频发为配电网的供电可靠性、安全性带来严重威胁,在此背景下,为增强中低压配电网故障恢复能力,研究自然灾害场景下考虑用户需求响应的中低压配电网弹性提升技术。首先,综合考虑用户差异化供电可靠性需求以及需求响应的运行特性,建立衡量配电网弹性的指标———停电损失;其次,提出基于供电优先级的需求响应控制策略,并建立计及需求响应的配电网弹性提升优化模型;最后,以IEEE33节点为例,对所述指标和模型进行验证。仿真结果表明:所提弹性提升优化模型可显著降低中低压配电网弹性恢复全过程的停电损失,提升灾害场景下配电网的运行弹性。

    Abstract:

    The frequent occurrence of natural disasters make a serious threat to the reliability and safety of power supply in distribution network. Under the background, the distribution network elasticity improvement technology for the medium and low voltage power system considering user demand response is studied to enhance its fault recovery capability. Firstly, the demand of reliability for user's differentiated power supply and the operation characteristics of demand response is considered, and then an index to measure the resilience of distribution network is established-outage loss. Secondly, a demand response control strategy is proposed on the basis of the power supply priority. In th end, an optimization model of distribution network resilience enhancement considering demand response is developed. The IEEE 33-bus system is simulated to verify the index and the model. It is shown that the optimization model of resilience enhancement can significantly reduce the outage loss in the whole process of resilience restoration in distribution network and improve its resilience under disaster scenarios.
