极端自然灾害下新型电力系统弹性提升措施研究及关键技术综述

A Review of Research and Key Technologies on the Resilience Improvement Measures of New Power Systems Under Extreme Natural Disasters

新型电力系统弹性是保障能源可持续发展和结构形态改革安全的基石。首先阐述新型电力系统弹性的概念,明确新型电力系统弹性在极端自然灾害下的演化过程,而后分析新型电力系统对弹性的影响,指出源-网-荷不确定性波动加剧、受灾系统时-空特性不均衡、动态控制系统可行性不足三个方面的挑战,从灾前规划配置、灾中管理控制和灾后恢复响应角度综述新型电力系统弹性的提升措施。最后对提升新型电力系统弹性的关键技术进行了归纳,明确弹性全时段不确定性表征和物联网与人工智能在弹性提升措施中的价值,并给出重点研究方向,从而为新型电力系统的弹性建设提供参考。

The resilience of novel power system is the cornerstone of ensuring the sustainable development of energy and the safety of structural reform.With the development of the economy,the society has put forward higher requirements for the system to resist extreme natural shocks,ensure rapid power recovery and load energy consumption.In this paper the concept of resilience of novel power system was first exponded,the evolution process of the resilience in novel power system under extreme natural disasters clarified,and then the impact of novel power system on the resilience analyzed.Three challenges were pointed out in terms of source-networkload uncertainty fluctuations,unbalanced spatiotemporal characteristics of disaster-hit systems,and insufficient feasibility of dynamic control systems.The measures to improve the resilience of novel power system were reviewed from the perspectives of pre-disaster planning and configura-tion,management and control during disasters,and post-disaster recovery response.Finally,the key technologies for improving the resilience novel power systems were summarized,and the full-time uncertainty representation of resilience and the value of IoT and artificial intelligence in resil-ience improvement measures were clarified.The key research directions were also given so as to provide reference for the resilience construction of novel power systems.
