基于电力潮流追踪与绿色电力交易的企业用电侧碳排放因子核算

Calculation of Carbon Emission Factors on the Corporate Electricity Consumption Side Based on Power Flow Tracing and Green Power Trading

用电侧碳排放因子的准确合理计算对精准评估各地区、各行业、各企业的用电碳排放量具有重要意义。构建了一种结合电力潮流追踪与绿色电力交易的企业用电碳排放因子计算模型与方法,基于发、用电企业的电力生产和消费数据、电力潮流分布数据以及绿色电力交易数据,挖掘用电侧碳排放量与企业所在位置、用电时段和绿色电力交易情况等因素之间的关系,实现用电侧碳排放因子的实时更新。最后通过IEEE 30节点和实际省级电网的算例分析证明了所提方法的有效性。

The accurate and reasonable calculation of the carbon emission factors on the electricity-consumption side is of great significance for the accurate assessment of the carbon emissions caused by electricity consumption of various regions,industries and enterprises.In this paper,a calculation model and method of carbon emission factors of corporate electricity consumption is constructed by combining power flow tracing and green power trading.Based on the power production and consumption data,power flow distribution data and green power trading data of power generation and consumption enterprises,the relationship among the carbon emissions on the electricity consumption side and the enterprise location,power consumption period and green power trading is researched to achieve real-time update of carbon emission factors on the electricity consumption side.Finally,the cases calcula⁃tions on both IEEE 30-bus and an actual provincial power grid verify the effectiveness of the proposed method.
