Review on the Resilience of New Power Systems with Flexible Resources under Extreme Weather Conditions

[Objective] Under China’s “dual carbon” goals，as energy decarbonization accelerates and renewable energy deployment enters a fast-growth phase，low-probability but high-risk extreme weather poses significant challenges to the safe and reliable operation of new power systems with high renewable energy penetration. Flexible power resources—such as electric vehicles and distributed generation—offer solutions to enhance system resilience during extreme weather. [Methods] This paper outlines the conceptual characteristics of power system resilience and examines the impact of extreme weather on new power systems. It reviews the resilience research of new power systems under extreme weather from three aspects：system component modeling under extreme weather，system resilience analysis methods，and resilience indicator frameworks. Furthermore，by analyzing the adjustable capacity of flexible power resources during extreme weather，the paper proposes strategies for enhancing the resilience of new power systems considering flexibility and extreme weather from four perspectives（generation，grid，load，and storage），and across three stages（prevention，emergency control，and rapid power restoration）. [Conclusions] Finally，the paper identifies research directions on the resilience of new power systems with flexible resources under extreme weather，aiming to establish a closed-loop risk management and resilience enhancement framework，and provide a theoretical basis for ensuring power supply during extreme weather.
