现有碳排放计算方法不能很好地满足碳排放区域逐渐细化和实时需求.为保证碳排放责任分摊的实时和准确,提出一种城市区域碳排放实时计算方法.利用改进的K-means聚类算法,对城市区域能源负荷的运行时段和运行场景进行聚类组合,得到典型碳排放特征.将区域单位电力碳排放量作为碳排放指标;归类运行时段和场景,计算各簇单位电力碳排放量和城市区域碳排放总量.基于中国东部某地区 “能源大脑”中部分能源消费历史数据进行验证,结果表明:该聚类方法和碳排放指标可以有效地实时计算城市区域碳排放总量.

Existing calculation methods of carbon emission cannot well meet the needs of gradual refinement and real-time of carbon emission regions. In order to ensure the real-time and accuracy of carbon emissions responsibility allocation, a real-time calculation method of carbon emissions in urban regions is proposed. The improved K-means clustering algorithm is used to cluster and combine the operating periods and operating scenarios of the urban area energy load,so as to obtain the typical carbon emission characteristics. The regional unit electricity carbon emission is proposed as a carbon emission indicator, the operating period and scenario are classified, and the unit electricity carbon emission and the total carbon emission of urban regions for each cluster are calculated. The proposed algorithm is verified based on part of the historical data of energy consumption in the energy brain of a certain region in eastern China. The results show that the clustering method and carbon emission indicators can effectively calculate the total carbon emission of urban regions in real-time.
