Abstract: In allusion to the situation that the existing transmission loss allocation method is hard to apply to the complex distribution network with the distributed generation, this paper carried out the research on the transmission loss allocation object and proposed a kind of improved average transmission loss allocation method, which could be applied to the complex distribution network with the distributed generation. This paper analyzed the current development of the distribution network and the distributed generation in certain city and explained that the distributed generation of this city was mainly connected to the low and medium voltage distribution network. This method was used to reasonably evaluate the transmission loss electric quantity and the economic benefit which should be allocated by the distributed generation of this city. The results show that the transmission loss electric quantity is larger, so as to let the distributed generation bear the certain amount
of the transmission losses.
Key words: distributed generation; distribution network; transmission loss; allocation
