Reliability Analysis of Distribution Network with Closed-loop Operation

The adjustment operation is crucial to power distribution network dispatching department. However, the current adjustment scheme is mainly based on experience and simple calculation of the operation. As the scale of distribution network and the number of accessing user increases, the wiring of the distribution network also becomes complicated. The existing manual-based operation mode adjustment method is not only inefficient, but also difficult to achieve optimal status. In order to solve complex calculation of large-scale distribution network system, this paper presents the fast distribution network supply reliability algorithm and its optimization strategy, proposing optimal strategy of inter-substation load transfer to improve the reliability of distribution network from different loops. The constraints of inter-substation transfer operation are also analyzed, proving of applying principles.
