An Emergency Dispatch Resilience Enhancement Method for N-k Faults in Urban Integrated Energy Systems Based on User Heating Demand

This paper proposes an urban integrated energy systems (UIES) resilience enhancement methodology that takes into account users' perception of heat used to ensure the dual benefits of users' lives and health and economic costs during the emergency phase after an extreme disaster. Based on the existing resilience enhancement methods, this paper introduces a compensation cost coefficient to represent the important load nodes in the UIES heat subsystem, and uses this to propose targeted rapid recovery measures. Secondly, considering the stochastic nature of user heating load demand and user thermal tolerance, the user's degree of thermal tolerance to indoor temperature and other multi-coupling influencing factors are used as adjustable indexes, and the corresponding economic cost compensation function is established according to the changes in the room temperature, to put forward the resilience enhancement means of real-time follow-up compensation of the user's thermal response feeling by the segmentation of the economic cost, and to establish the resilience enhancement means that take into account the economic benefits and the user-side user thermal response feeling of the service provider. A resilience scheduling model is established that takes into account both the economic benefits of the service provider and the thermal response feelings of the users on the user side. Finally, the example verifies that the emergency scheduling method effectively improves 3 °C of the indoor temperature and the participation of users in the recovery process and provides more accurate recovery results.
