| Abstract: | With regard to an objective function for maximizing the reliability and minimizing the feeder loss, constraint conditions are considered as actul situation and operation limits by transforming the muti-objective problem to singal-objective one using the method of weighting. Furthermore, in order to reduce the length of chromosome, a distribution simplifying method is presented, both encoding method and genetic operation based on loop is proposed,these strategies greatly reduce the production of infeasible solutions and enhance the efficiency of the algorithm. All the results from the examples prove the feasibility and validity of the proposed algorithm. |
