摘 要:針對目前的網(wǎng)損分攤方法難以應用到結(jié)構(gòu)復雜的含分布式電源(DG)的配電網(wǎng)的情況,對網(wǎng)損分攤的對象進行了研究,并提出了一種改進平均網(wǎng)損系數(shù)法,該網(wǎng)損分攤方法可應用于結(jié)構(gòu)復雜的含分布式電源的配電網(wǎng)。分析了某市配電網(wǎng)及分布式電源的發(fā)展現(xiàn)狀,說明該市電網(wǎng)的分布式電源主要接入于中低壓配電網(wǎng)。利用該方法對該市分布式電源應分攤的網(wǎng)損電量和經(jīng)濟效益進行合理評估,結(jié)果表明該市分布式電源應分攤的網(wǎng)損電量較大,分布式電源理應承擔一定的網(wǎng)損。
關(guān)鍵詞:分布式電源;配電網(wǎng);網(wǎng)損;分攤

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
