摘　　要：全面考虑配电网的实际情况和运行要求,以网损最低和可靠性最高作为目标函数,利用加权系数法将多目标优化问题转化为单目标优化问题.通过简化配电网的结构,减少了遗传算法(GA)染色体的长度,设计了基于环路的编码方法和遗传操作,避免了大量不可行解的产生,大幅度提高了计算效率.给出的算例验证了该算法的有效性.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.
