电力系统碳排放流的递推算法

Recursive Calculation Method of Carbon Emission Flow in Power Systems

碳排放流理论为电力系统中碳排放责任的分摊提供了新的视角。基于节点碳势计算中的邻接特性,文中提出了电力系统碳排放流的递推算法,论述了递推算法的基本原理及计算过程。然后,分析对比了递推算法和已有的直接算法的特点和适用性,并进一步将二者结合,提出了碳排放流的协同计算流程。最后,以简单电力系统为分析对象,具体说明了所提递推算法的递推过程。并以IEEE 24节点系统和挪威2 383节点系统为例,测试了递推算法在实际电力系统应用中的有效性。

The theory of carbon emission flow（CEF）provides a new perspective for the allocation of carbon emission responsibility in power systems.Based on the fact that the carbon emission intensity of a node only depends on the CEF related information of its adjacent nodes and branches,this paper proposes a recursive calculation method of CEF in power systems.The basic principle of the proposed recursive CEF calculation method is firstly elaborated and its calculation process is provided.Then,the characteristics and applicability of the recursive method and the existing direct method are analyzed.By combining the two methods,a coordinated calculation procedure is proposed.Finally,the solution process of the recursive method is illustrated based on a simple power system.The case studies of IEEE 24-bus system and the Nordic 2 383-bus system verify the effectiveness of the proposed recursive method in the actual power systems.
