基于时序仿真的用户侧碳排放评估模型

Time Sequence Simulation-based Modeling of User-side Carbon Emission Estimation

碳排放始于电厂,终于电能消费终端,用户侧碳排放量的精确评估是促进碳减排快速达成的重要技术保障。在碳排放量的评估过程中,和传统的排放系数法相比,电力系统碳排放流理论为碳排放的精确评估提供了新的思路。围绕负荷用电需求,综合考虑各类电源特性,构建了中短期生产模拟仿真模型,并求解得到了各台机组出力方式以及系统潮流分布;基于电力系统碳排放流理论,求得系统中碳排放流分布,并确定系统内各节点碳排放量。以简化的实际电网为例,测试了所提模型在实际电力系统应用中的有效性。

Carbon emissions originate from power plants and end in power consumption terminals.Accurate estimation of carbon emissions on the user side is an important technical guarantee to promote rapid achievement of carbon emission reduction.Compared with the traditional emission coefficient method,the carbon emission flow theory of power system provides a new idea for accurate estimation of carbon emissions.In this paper,the short-term production simulation model is established based on load demand and characteristics of various power sources,and the output mode of each unit and the power flow distribution of the system are obtained.Based on carbon emission flow theory of power system,distribution of carbon emission flow and consequent carbon emission of each node in the system is obtained.Taking a simplified actual power grid as an example,the applicative effectiveness of the proposed model is verified.
