极端高温天气下电-气综合能源系统两阶段预防-恢复策略
Two-stage Prevention-recovery Strategy for Electricity-gas Integrated Energy System Under Extreme High-temperature Weather
摘要
Abstract
The frequent occurrence of extreme high-temperature weather poses a serious threat to the safe and stable op-eration of an electricity-gas integrated energy system.To improve the level of system resilience,the optimal layout of emergency resources under extreme high-temperature weather and the optimal repair sequence method after the outage of multiple lines are proposed.First,the multiple effects of high temperature on the system are analyzed,including the load surge,abnormal pressure of natural gas pipeline network,photovoltaic output attenuation and an increase in the equipment failure rate.Second,under the premise of considering important load nodes,a two-stage strategy for improv-ing the system resilience is constructed,i.e.,optimizing the layout of emergency resources such as electricity and gas storage before the disaster,and solving the problem of optimal repair sequence of lines and collaborative scheduling of emergency resources during the disaster.The Monte Carlo method is used to generate a scenario set of system outage lines,and a mixed integer programming model is used to realize the coordinated recovery of electricity-gas system across network faults.Simulation results show that compared with the traditional recovery method,the proposed strategy can reduce the total economic losses by 43.69%and effectively improve the resilience of the electricity-gas integrated energy system in an extreme high-temperature environment.关键词
