Distributed Low-Carbon Economy Scheduling for Integrated Energy System With Multiple Individual Energy-Hubs

在全球各国推行节能减排政策的激励下,低碳型综合能源系统将成为未来能源结构转型的发展方向。考虑各子区域由不同的能源供应商负责运营的实际场景,首先提出了一种含多个能源集线器的综合能源系统基本框架,分析了不同主体的运行特性和运行约束,并引入了交替方向乘子法,构建了计及CO2排放水平的综合能源系统分布式日前低碳经济调度模型。最后运用实际数据进行仿真,从各个子区域能源集线器的供能注入功率和储能设备调度结果、低碳减排经济性惩罚对系统的作用以及分布式算法的有效性3个方面进行分析,验证了所提模型和求解方法的实用性和准确性。

In the context of worldwide energy conservation and emission reduction,integrated energy systems(IES)considering low carbon emissions will inevitably become development direction in modern ages.Considering a scenario with multiple autonomous decision-making energy entities,a basic framework of integrated energy system with various energy-hub(EH)is proposed.Then operation characteristics and operation constraints of EH and IES are analyzed,and a day-ahead low-carbon economy scheduling model for distributed integrated energy systems is established based on ADMM(alternating direction method of multipliers).Finally,simulation is carried out using practical data from several aspects,including operation of sub-region energy-hub,scheduling results of energy storage equipment,effects of carbon emissions punishment for system,and validity of distributed algorithm,verifying practicality and accuracy of the proposed model and method.
