Abstract

Flexible Power Link (FPL) devices, based on Power Electronics (PE), are used in Distribution Networks (DNs) to enhance flexibility and consumer reliability. This paper introduces an algorithmic approach to configure two FPL devices in a ring-shaped network in Spain, aiming to improve the consumer reliability during outage events. These outages are severe, affecting thousands of consumers and causing significant infrastructure damage, with current flow in one segment reaching 106% of the cable rating. The proposed algorithm successfully identifies a suitable FPL configuration, resulting in a more balanced current distribution between the active segments during the event. In the same scenario, the FPLs reduce the segment’s loading to 75%. It is expected to enhance the distribution index TIEPI by reducing the frequency of those events, and the total time of the interruption.

基于电力电子设备（PE）的柔性电力链路（FPL）设备用于配电网络（DN），以提高灵活性和用户可靠性。本文介绍了一种在西班牙环形网络中配置两个 FPL 设备的算法方法，旨在提高停电事件中的用户可靠性。这些停电事件十分严重，影响到数千名用户，并对基础设施造成严重破坏，其中一段的电流达到电缆额定值的 106%。所提出的算法成功地确定了合适的 FPL 配置，使事件发生期间有功段之间的电流分布更加均衡。在同样的情况下，FPL 将分段的负载降低到 75%。通过降低这些事件发生的频率和中断的总时间，有望提高配电指数 TIEPI。

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.
