We solve the problem of reconfiguration of a primary distribution network with feeders powered from several independent sources. A high-performance algorithm is applied to reconfigure the primary distribution network by the loss minimization criterion. The algorithm constructs the maximum spanning tree on the network graph and determines the composition of branches of independent loops. The information on the distribution network topology features allows determining the variants of tie switches that may be used to restore the power supply at an emergency outage of any sectionalizing switch and any circuit breaker, and the subsystems of trees in the network, whose loads have no reserve power supply. The efficiency of the offered algorithm is verified by the coincidence of the reconfiguration results obtained on its basis for the distribution network regarded as a test one with the results obtained for this network by other methods. The algorithm efficiency is also illustrated by an example of a real municipal distribution network. (C) 2019, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.
