A General Power islanding harmony with division method algorithm

The present invention relates to a method of dividing power distribution islanding algorithm based on harmony, with the present invention, power division method harmony islanding algorithm, the load switch to restore up operation switch and a target minimum, considering the active islanding balance, but line current constraints such carrier, each of the distribution network coding node 0-1, breadth-first search algorithm in conjunction with a specific embodiment islanding, and calculates the objective function value of each island by harmony algorithm to adjust the island programs, evaluate, update, and then carry out the optimal solution for the current trend test, finally gives superior islanding scheme. The present invention is a method to achieve distribution network islanding problem comprehensive solution space search algorithm based on harmony, we can take advantage of local information and individual information to guide the global community to further the search algorithm, and its principle is simple, less adjustable parameters, islanding problem solving when divided island can get the best solutions in a short time.
