摘 要:根據(jù)電能交換機能平滑分布式電源出力,結(jié)合分布式電源出力、孤島可靠性模型,基于傳統(tǒng)配電網(wǎng)可靠性評估算法,運用圖模型提出了含電能交換機的配電網(wǎng)可靠性評估算法。采用模型和所提出的算法對改造后的IEEE RBTS BUS6系統(tǒng)的F3主饋線進(jìn)行了可靠性評估。結(jié)果表明,電能交換機與分布式電源聯(lián)合使用才能充分發(fā)揮其作用,電能交換機的加入能夠有效減少負(fù)荷點停電時間,減少的程度與其位置有關(guān)。

Abstract: According to the function of smooth distributed power supply of power switch, combining with the distributed power supply and the island reliability model, and based on the reliability evaluation algorithm of traditional distribution network, the reliability evaluation algorithm of distribution network with energy switches was proposed by using the graph model. The model and the algorithm are used to evaluate the reliability of the F3 main feeders of the modified IEEE RBTS BUS6 system. The results show that the combined use of power switch with distributed power supply can fully play the role of them. The power switch can effectively reduce the load point outage time, and the degree of reduction is related to its location.
Key words: graph model; energy Internet; energy switch; distribution network
