摘要
传统微网系统能源利用率低、运行成本高,文章提出区域能源互联网的"源-网-荷-储"多能互补系统构架;以系统运行成本、环境保护成本和一次能源使用率最低为目标函数,建立了电-气互联的区域能源互联网的"源-网-荷-储"的日前动态经济调度多目标优化调度模型。分析了电-气互联的区域能源互联网的"源-网-荷-储"系统的综合运行效益;制定了支持电-气互联的区域能源互联网的"源-网-荷-储"系统设备的运行策略;通过春夏、秋冬季典型日负荷仿真分析,验证了在传统微网系统中加入气网和储能,系统日总运行成本比传统微网系统日总运行成本节约13%左右。
The traditional microgrid system has low energy efficiency and high operating cost.This paper proposes the"source-net-charge-storage"multi-energy complementary system architecture of regional energy Internet.Taking the lowest system operation cost,environmental protection cost and primary energy utilization rate as the objective function,the day-ahead dynamic economic dispatching multi-objective optimization dispatching model of"source-net-charge-storage"of regional energy Internet with power-gas interconnection was established.The comprehensive operating benefits of the"source-net-charge-storage"system of the regional energy Internet in electric-gas interconnection are analyzed.The operation strategy of"source-network-charge-storage"system equipment for regional energy Internet supporting electricity-gas interconnection is formulated.Through the simulation analysis of typical daily load in spring,summer,autumn and winter,it is verified that adding gas network and energy storage into the traditional microgrid system can save about 13%of the total daily operating cost of the system compared with the traditional microgrid system.
