Abstract

With the increasing frequency of extreme events, distribution networks are facing more severe challenges in terms of secure operation. This paper proposes a resilience enhancement method for distribution networks that combines demand response (DR) scheduling and network reconfiguration, aiming to improve both the resilience and economic efficiency of the grid when facing extreme events. Before the occurrence of extreme events, based on the predicted time and zone of the disaster, the load consumption periods after the disaster are scheduled in advance, and the energy storage system (ESS) is also scheduled to avoid the high costs associated with post-disaster load shedding. After the event, considering the differentiated characteristics of various fault scenarios, network reconfiguration is used to form restorative islands. The effectiveness of the proposed method is verified through two case studies based on the IEEE 33-bus system and the IEEE 123-bus system.

考虑需求响应的配电网两阶段弹性增强方法

随着极端事件的日益频繁，配电网的安全运行面临着越来越严峻的挑战。本文提出了一种将需求响应调度与网络重构相结合的配电网弹性增强方法，旨在提高电网在面对极端事件时的弹性和经济效率。在极端事件发生前，根据预测灾难发生的时间和区域，提前规划灾后负荷消纳时段，同时对储能系统进行调度，避免灾后减负荷带来的高额成本。事件发生后，考虑到各种故障场景的差异化特点，采用网络重构的方式，形成恢复性孤岛。通过基于IEEE 33总线系统和IEEE 123总线系统的两个实例研究，验证了所提方法的有效性。

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
