Abstract

A building distributed energy system is an efficient low-carbon energy supply option. As extreme weather events become more frequent, clarifying the ability of distributed energy systems to withstand extreme weather is fundamental to assessing their potential for future applications. However, the impact of extreme weather on the reliability of distributed energy systems is unclear. To fill this gap, a method based on mixed-integer linear programming is proposed to quantitatively assess the impact of extreme weather on the reliability of distributed energy systems. The effects of system location, operating scenarios, and operating strategies on system reliability under extreme weather are explored. Taking three Chinese cities that had heat waves as examples, the results show that only the reliability of the system in Tianjin is affected by the operation strategy. The electricity supply reliability of the system with grid-connected operation is 100 %, but the system cooling supply reliability may decrease by up to 5 %. When the system operates in islanded mode, heat waves have a greater impact on the reliability of the system located in the south than that in the north. The level of power supply incidents caused by system-reduced reliability in Chongqing, Wenzhou, and Tianjin is classified as major-normal, special major-normal, and major/large-short. The minimum cooling supply factor is 80 %, 94 %, and 100 %. The longer the heat wave lasts, the less reliable the system is. This study provides a theoretical foundation for improving the resilience of distributed energy systems to extreme weather.

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
