Abstract

This paper presents a novel sectionalizing method for the build-up strategy in power system restoration. Power system restoration is the procedure of restoring power system elements after a partial or a complete blackout. Because of its economic and political importance, different strategies have been developed for power system restoration. One of the most practical and economical is the build-up strategy that includes the process of restoring separated parts (islands) in the power system and interconnecting them afterwards. This paper intends to develop a systematic algorithm for sectionalizing a power system considering various constraints such as black-start capability of generators, power supply-demand balance and independence of islands. Moreover, utilizing Wide Aare Measurement System (WAMS), each island will be fully observable in this method which is a crucial requirement for the restoration process. The New England 39 bus power system is used to demonstrate the proposed algorithm and verify the results. The proposed method is also applied to the IEEE 118 bus system as a large-scale power system to prove its capability in practical systems.

基于广域测量系统的电力系统恢复分段方法

本文提出了一种新的分段方法用于电力系统恢复中的叠加策略。电力系统恢复是在部分或完全停电后恢复电力系统元件的过程。由于其在经济和政治上的重要性，人们制定了不同的电力系统恢复策略。其中最实用和经济的是重建策略，包括恢复电力系统中分离的部分(岛屿)并在之后将它们互连。考虑发电机黑启动能力、电力供需平衡和岛屿独立性等多种约束条件，提出了一种系统的电力系统分区算法。此外，利用广角测量系统(WAMS)，该方法可以完全观察到每个岛屿，这是恢复过程的关键要求。以新英格兰39母线电力系统为例，对所提出的算法进行了验证。并将该方法应用于ieee118总线系统作为大型电力系统，验证了该方法在实际系统中的应用能力。
