Abstract

Automatic reclosing is an important means to improve reliability of power supply in distribution networks. With the high penetration of distributed energy resources, distributed energy resources may still connect to the grid when automatic reclosing actions, which would lead to reclosing failure and seriously affects the safe operation of distribution networks. Hence, non-voltage checking reclosing method is proposed to solve the above problem, yet, non-voltage checking reclosing method cannot be implemented since there is no line-side voltage transformer mounted in substations in many cases, so an automatic reclosing method which is suitable for high penetration of DERs is urgently needed. An automatic reclosing method based on topology identification is proposed in this paper, in which automatic reclosing is realized by identifying the automatic reclosing application topology in real time. The proposed method could adapt to the frequently changes of dynamic topology in the distribution network, and realize fast and reliable automatic reclosing so as to improving the reliability of power supply. The effectiveness of the proposed method is verified by the test results conducted on a static active distribution network simulation system.
