摘　　要：针对韩城采气管理区的中浅层煤层气井开采存在采矿设备高能耗、高电力成本及其引致的高碳排放量等问题,研究提出了煤层气井场光储系统设计与能源协调优化模型和煤层气井场的负荷模型,以准确捕捉不同工况下抽油机系统的能耗特性,分析负荷变化下抽油机系统的功耗变化关系。设计了适合于煤层气井场的光储系统进行能源管控,利用构建能源协调优化模型,确定了最佳光伏阵列容量、蓄电池规模,以及不同时段蓄电池和电网供电的工作状态。研究表明优化后的光储系统能显著减少运营成本,煤层气井场的年度总成本降低了大约24.93%,验证了所设计光储系统和能源协调优化模型对于改善煤层气井场电网节能效率的有效性,为中浅层煤层气井场的综合能源管理控制技术应用提供了可行的解决方案。In order to address issues such as high energy consumption,costly power usage,and excessive carbon emissions caused by mining equipment in the middle-shallow coalbed methane wells within the Hancheng Gas production management area.In this paper,the design of photovoltaic energy storage system,energy coordination optimization and load model of coalbed methane well site are put forward,which aims to accurately capture the energy consumption characteristics of the pumping unit system under different operating conditions,and analyzes the relationship between power consumption and load variation of pumping unit system.A photovoltaic energy storage system suitable for coal-bed methane well site is developed for energy management,the optimal photovoltaic array capacity,battery scale,and the working state of battery and grid power supply in different periods are determined through the construction of energy coordination optimization model.The research demonstrates that the optimized photovoltaic energy storage system can significantly reduce operational costs with an approximate 24.93%decrease in annual total cost at coalbed methane well sites.This verifies the effectiveness of both the developed photovoltaic energy storage system and energy coordination optimization model in enhancing energy-saving efficiency within coal bed methane well site grids,while providing a feasible solution for integrating energy management and control technology into middle and shallow coalbed methane operations.
