Abstract

Under the background of global climate change, extreme weather events such as extreme high temperature, cold and freezing temperature, and strong wind and heavy rain occur frequently, which seriously threaten the operational reliability of integrated energy system （IES）. Based on this, we firstly focus on the reliability assessment methods of integrated energy system under extreme weather, and analyze the impacts of three types of extreme weather, namely, extreme high temperature, severe cold and freezing temperature, and strong wind and rainstorm, on the energy production equipment （including power generation, heat supply, and energy storage equipment） and the energy transmission network in various aspects. Secondly, we comprehensively review the integrated energy system reliability assessment methods under these extreme weather conditions, and explore the shortcomings of the existing methods in terms of meteorological data processing, system coupling modeling, multi-method fusion, toughness quantification, and multi-factor considerations. Finally, possible future research directions are proposed for the operational reliability assessment of integrated energy systems under extreme meteorological conditions, aiming to provide certain theoretical and practical references for improving the accuracy and effectiveness of IES reliability assessment under extreme meteorological conditions, so as to guarantee the safety and stability of energy supply.
