First, to use power generation method to realize the power flow calculation;
Second, distribution network after the distribution network to refactor tend to require or radiation network, cannot have ring and an island, this mainly through coding way to avoid the infeasible solution, that there are some studies, such as according to the loop coding;
Third, the present research hot spot is introduce the distributed power and reactive power compensation;
Fourth, there are two categories of goal, one kind is minimum network loss, another kind is to restore a maximum load;
Fifth, for failure recovery, generally to be in a distributed power supply, increase the source, if there is only one source, the question is too simple, can also according to the importance of load classification,
Hope these points to be of help,
