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

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-network-load 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 configuration, 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 resilience improvement measures were clarified. The key research directions were also given so as to provide reference for the resilience construction of novel power systems.
