Carbon flow calculation method for node/branch of power network

The invention provides a carbon flow calculation method for a node/branch of a power network. A carbon flow state is determined according to power flow distribution so as to identify a path of carbonemission of a system in production, transmission and consumption. The carbon flow calculation method mainly comprises the step of calcuatling a carbon potential of the node of the power network, a carbon flow rate of the branch and a carbon flow rate of a load. By the method for calculating and analyzing carbon emission flow, an enterprise is helped to identify a high-carbon element in a power system so as to propose a targeted optimization measure, and a guidance help is played for low-carbon development and planning of a future power grid. 本发明提供种电力系统供用电网络节点/支路的碳流计算方法，依据潮流分布定量确定碳流的流动状态，以辨识系统中碳排放在产生、传输和消费中的去路。主要包含：电力网络节点碳势、支路碳流率及负荷碳流率的计算。运用该方法进行碳排放流的计算与分析，有助于企业识别电力系统中的高碳要素，以提出针对性的优化措施，对未来电网面向低碳的发展与规划起到指导性的帮助。
