The components of integrated electrical-water-gas system (IEWGS) may break down more easily when extreme natural disasters such as the occurrence of earthquakes, and this may affect the normal operations of the integrated system. Currently, the researches on the impact of demand response (DR) on the resilience of IEWGS are rarely available. This paper studies the load recovery strategy for IEWGS under the conditions of extreme natural disasters. An integrated DR model is established based on the coupling characteristics between multiple energy sources and the dynamic response characteristics of users. A DR participation mechanism is also designed, which aims at improving the resilience of IEWGS. Moreover, an emergency response optimization model of the IEWGS is established. Case study results show that the proposed load recov-ery strategy can improve the load recovery ratio and effectively enhance the resilience of the system.
