中文摘要:

      分布式电源接入配网运行引起功率输送损耗以及配网负载率的变化，使得含分布式电源的配网线损分摊工作更为复杂。从传统配网线损分摊原理出发，分别基于比例分摊、市场经济、敏感系数分析等不同角度全面概述现有的配网线损分摊方法，并分析考虑分布式电源后各方法有可能存在的问题；在此基础上，从改进传统网损分摊方法、挖掘新型网损分摊方法、考虑配网运行经济性、考虑分布式电源对配网的影响等方面着手，阐述分布式电源（DG）并网后的配网线损分摊新趋势。

英文摘要:

      The access of distributed generation to distribution network will lead to the change of power flow, power transmission loss and load rate of the distribution network, which makes the network loss allocation more complicated. Based on the principle of traditional line loss allocation, a comprehensive overview of the existing methods of line loss distribution is presented based on proportion sharing, market economy and sensitivity coefficient analysis,and the possible problems of each method after considering the distributed power supply are put forward. Furthermore, the new trend of loss allocation of distribntion network with DG is prospected in the aspects of improving the traditional method of network loss allocation, exploring new methods of network loss allocation, considering the operation efficiency of distribution network, considering the influence of distributed power to distribution network, etc.
