摘　　要：在地震等极端自然灾害下,电-水-气综合能源系统的元件故障概率会大幅提升,进而严重影响系统的正常运行。针对目前忽略用户在提升系统弹性上的潜力,基于综合需求响应对电-水-气综合能源系统负荷恢复策略进行研究。首先基于多能源之间的耦合特性与用户的动态响应特性建立综合需求响应模型。其次设计系统与用户协同的需求响应参与机制,将用户的综合需求响应作为灵活性资源融入极端灾害下的负荷恢复策略中,有效、合理地提升系统弹性。最后建立电-水-气综合能源系统负荷恢复优化模型,通过改造的电-水-气综合能源系统对所提出的方法进行了模拟和验证。结果表明,所提出的负荷恢复策略能够提高灾后系统负荷的恢复比例,有效增强系统的弹性。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 recovery strategy can improve the load recovery ratio and effectively enhance the resilience of the system.
