Abstract：Aiming at the constraint of operation times of all switches and the inefficiency of harmony search algorithm，the improved

optimal fuzzy C-means clustering technology and the improved harmony search algorithm were proposed. The former was applied to

classify the operation state in a time interval according to load data that the dynamic reconfiguration of distribution network was converted

to the multiple static reconfigurations that take the corresponding cluster center as the representative load. The latter was applied to solve

the static reconfiguration. The optimal network structure at any time was determined by the corresponding cluster center's reconfiguration

result，at the same time，the reconfiguration time and the operated switches were known. On the basis of IEEE-33bus system's load data，

one day's load data was constructed and the dynamic reconfiguration was carried out. The results indicate that the proposed method can

strictly limit operation times of switches and improve the efficiency of harmony search algorithm.
