摘　　要：电-气区域综合能源系统(electricity-gas regional integrated energy system,EGRIES)多故障恢复包含重构和多个故障元件的抢修,考虑系统运行方案调整对恢复力的提升及经济运行下,故障恢复的规模大且复杂度高。为此,提出了一种重构与抢修协同下的EGRIES多阶段博弈故障恢复方法。首先,进行EGRIES多故障恢复分析,建立量化的恢复力评价指标,提出多阶段主从博弈故障恢复方法框架,主体、从体博弈者分别为故障恢复方案制定模块和运行方案制定模块;然后,建立主体博弈者模型,并计及配电网与配气网的利益均衡,建立配电网与配气网经济运行非合作博弈的从体博弈者模型,再基于粒子群优化算法进行求解。最后,采用由IEEE-33节点配电网和15节点配气网构成的EGRIES进行算例分析,较传统优化方法,所提方法下负荷损失价值减少了19.98%,系统运行成本降低了6.39%,表明所提方法能在提升恢复力的同时兼顾系统运行成本的降低。Multi-fault recovery of the electricity-gas regional integrated energy system(EGRIES)contains reconfiguration and multiple faulty components repair.Fault recovery is large-scale and complex considering system operation scheme adjustments for resilience improvement and economic operation.Therefore,a multi-stage game fault recovery method for EGRIES under reconfiguration and repair coordination is proposed.Firstly,a multi-fault recovery analysis of EGRIES is carried out,and quantitative recovery capability evaluation indexes are established.The framework of a multi-stage master-slave game fault recovery method is proposed,with the main and the slave gamers being the fault recovery strategy formulation and operation strategy formulation respectively.Then,the main game model is established,and considering the equilibrium of interests between the distribution network and the gas distribution network,the slave game model of the economic operation of distribution network and gas distribution network in a non-cooperative game is established.Further,it is solved based on particle swarm optimization algorithm.Finally,an example analysis is carried out using EGRIES consisting of an IEEE-33-node distribution network and a 15-node gas distribution network.Compared with the traditional optimization method,the load loss value of the proposed method is reduced by 19.98%and the system operating cost is reduced by 6.39%,indicating that the proposed method can improve resilience while reducing the system operating cost.
