Resilience Assessment of Regional Electric-Thermal Integrated Energy Systems Based on Diverse User Demands

In recent years, the temporal and spatial infrastructure failures of regional integrated energy systems (RIES) due to various types of extreme natural disasters have been increasing, leading to significant impacts on social production and life. This paper proposes a resilience assessment system based on the demand of multiple users. Firstly, different heat loss coefficients are determined by the indoor temperature of various types of building users; secondly, the computation process of system resilience indexes is introduced by taking the ice hazard as an example; and lastly, the method proposed in this paper is tested in an integrated 9-node and 6-node electric-thermal network. The validity of the multivariate heat demand resilience assessment method is verified by the calculation case.
