基于图论和潮流追踪的网损分摊方法

Network Loss Allocation Based on Graph Theory And Power Flow Tracking

随着电力系统各经济主体的多元化发展,传统的网损分摊方法由于计算过程复杂已不能满足多主体分摊的需求。提出了一种基于图论和潮流追踪的网损分摊方法,首先以区域为经济主体,基于图论将复杂电力网络划分成多个区域,然后采用潮流追踪法对各区域主体进行网损分摊计算;其次在区域内以独立个体为经济主体进行网损分摊,并考虑了区域分摊损耗对独立个体网损分摊的影响,显著降低了计算的复杂性,提高了计算速度,最后以IEEE14节点数据为例进行仿真计算,验证了本文提出的分摊方法的有效性和优越性。

With the diversification of economic subjects in power system,traditional network loss allocation method is too complicated in calculation to satisfy the needs of multi-subject allocation.This paper proposed a network loss allocation method based on graph theory and power flow tracking.According to graph theory,we took regions as economic subjects and divided the complex power network into multiple regions.Then,we calculated the network loss allocation of each region by power flow tracking method.Next,we subjected the areas with individual economic subject to loss allocation,and took into consideration the influence of regional sharing loss to individual loss allocation.The proposed method significantly reduces the computation complexity and accelerates the calculation speed.Finally,we took IEEE14 node data as an example for simulation calculation,which verifies the effectiveness and superiority of the proposed allocation method.
