摘　　要：为合理评估高压输配电力网架中绿色电力的传输流向,精准分析用户用能中绿电占比,为企业电碳排放核查提供有力数据支撑,提出了一种基于电网潮流拓扑分析的区域可再生能源传输流向研究方法。该方法将区域的电网模型简化为以电力潮流拓扑网架模型,基于实时电力潮流走向生成机组注入矩阵、节点潮流矩阵与节点负荷矩阵,依托深度优先搜索算法,溯源绿色电源至用户的所有电力传输路径,计算从绿色电源至各用户的绿色电力分流占比。通过IEEE算例系统与实际地区网架验证了算法的有效性与快速性,可以服务区域电网公司与电力用户,精确地追踪绿色电源输送至各类型负荷的消纳情况。In order to further reasonably evaluate the transmission direction of green electricity in high-voltage transmission and distribution networks and accurately analyze the proportion of green electricity in user consumption,thereby providing persuasive data support for corporate electricity carbon emission verification,this paper proposes a research method for regional renewable energy transmission direction based on power grid flow topology analysis.This method simplifies the regional power grid model into a power flow topology network model,based on real-time power flow direction generator unit injection matrix,node flow matrix,and node load matrix.Furthermore,relying on a depth-first search algorithm,it traces all power transmission paths from green power sources to users and calculates the proportion of power diversion from green power sources to each user.This method has been validated for effectiveness and speed through the IEEE example system and actual regional grid frameworks.It can serve regional power grid companies and electricity users by precisely tracking the consumption of green power delivered to various types of loads.
