摘要
分布式能源系统具有能源利用率高、能效梯级利用、运行灵活等优点,对实现能源可持续发展有重要意义。为了提升长输管道压气站的经济效益,从能源结构角度优化可以进一步达到节能降耗的目的。针对中亚管道某压气站,对分布式能源系统的运行方案进行合理规划,建立了分布式能源系统运行优化的混合整数线性规划(MILP)模型,该模型以分布式能源系统总耗气量最低为目标函数,考虑了系统中不同设备的能量平衡约束以及运行约束,以不同设备的开启方案与选定设备的负荷分配为决策变量。以中亚管道某压气站为例,应用该模型得出了最优的分布式能源系统运行方案,并通过能耗、经济计算论证了该方案的合理性。
Distributed energy system has the advantages of high energy utilization,energy efficiency cascade utilization,and flexible operation.It is of great significance to realize the sustainable development of energy.In order to improve the economic benefits of the compressor station of long-distance pipeline and further achieve the purpose of energy saving and consumption reduction from the perspective of energy structure optimization,this paper makes reasonable planning for the operation scheme of the distributed energy system for a compressor station of Central Asia pipeline,and establishes a Mixed Integer Linear Programming(MILP)model for the operation optimization of distributed energy system.This model takes the lowest total gas consumption of the distributed energy system as the objective function,the energy balance constraints and operation constraints of different equipment in the system are considered,and the opening scheme of different equipment and the load distribution of selected equipment are taken as decision variables.Taking a compressor station of the Central Asia pipeline as an exam-ple,the optimal operation scheme of the distributed energy system is obtained by this model,and the rationality of the scheme is demonstrated by energy consumption and economic calculation.
