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.
