Then based on the genetic algorithm is applied to distribution network reconfiguration can produce a large number of infeasible solution problem put forward the following improvement strategies: in the coding method is more suitable for the produce of the feasible solution of the method, i.e., to ensure the power supply forced some switch must be in a closed state. Using a typical model are checked, and the results show that the proposed genetic algorithm coding mode operation efficiency is improved, can be effectively applied to distribution network fault recovery strategy.
