摘　　要：针对电力系统故障导致的电压暂降通过电-气耦合设备对系统造成多次影响的问题,提出了一种缓减电压暂降影响的电-气综合能源系统储气装置选址定容方法。分析了电力系统发生电压暂降事件对电-气综合能源系统的影响;基于灵敏度分析提出了天然气系统储气装置选址方法;综合考虑投资成本与效益,以安装储气装置后效益的最大值为目标函数,确定储气装置最佳配置方案。通过对由IEEE 14节点电力系统和11节点天然气系统构成的电-气综合能源系统进行算例分析,验证了该缓减方法的正确性与有效性。Aiming at the voltage sag caused by power system fault affects the system many times through electricity-gas coupling equipment,a location and constant volume method of gas storage device in integrated electricity-gas energy system for mitigating voltage sag effect is proposed.The impacts of voltage sags in power system on the integrated electricity-gas energy system are analyzed.Then,the location method of gas storage device in natural gas system is proposed based on the sensitivity analysis.Furthermore,with the comprehensive consideration of investment cost and benefit,the best configuration scheme of gas storage device is determined by taking the maximum benefit after installing gas storage device as the objective function.The correctness and effectiveness of the mitigation method are verified by analyzing an example of the integrated electricity-gas energy system composed of IEEE 14-bus power system and 11-node natural gas system.
