【 摘 要 】

The traditional distribution network reconfiguration method does not consider the impact of switching operations, resulting network equipments voltage instability and user blackouts in actual implementations. In this paper, the loop operation security constraints have been fully taken into account as establishing distribution network reconfiguration model by introducing constraints into the traditional model. The greedy random adaptive search procedures (GRASP) is adopted to obtain optimal solution and detailed steps of reconfiguration scheme and switching operation for distribution network, which ensures the solution is realized without network equipments voltage instability and user blackouts. After IEEE 14-bus system verification, this method shows its better adaptability and practical value, which fully combines actual work statues to improve distribution network reliability.
