摘　　要：为解决风电弃风和运行成本的问题,提出了考虑随机网络约束的电力天然气耦合系统与压缩空气储能系统的联合优化模型。分析了电力天然气混合系统的运行方式,建立了两阶段电力天然气耦合系统运行优化模型。第一阶段针对日前市场,第二阶段针对实时市场,分别考虑相应的电力系统约束、天然气系统约束以及耦合系统约束,并考虑随机网络约束,利用混合整数非线性规划求解。通过仿真分析,说明混合系统在风电弃风、负荷削减以及运行成本方面的影响。In order to solve the problems of wind power curtailment and operation cost,a joint optimization model of the power and natural gas coupling system and the compressed air energy storage system considering stochastic network constraints is proposed.The operation mode of the power and natural gas hybrid system is analyzed,and a two-stage power and natural gas coupling system operation optimization model is established.The first stage is for the day-ahead market,and the second stage is for the real-time market,considering the corresponding power system constraints,natural gas system constraints and coupled system constraints,and considering random network constraints,using mixed integer nonlinear programming to solve.Through the simulation analysis,the influence of the hybrid system on wind curtailment,load reduction and operating cost is illustrated.
