Reliability self-recovery method based on BGA for distribution network

针对配电网发生支路故障时缺乏快速且有效的恢复方案,从而导致可靠性下降的问题,提出了一种基于支路分组算法的配电网可靠性自恢复方法.在结合配电网网络结构基础上,将该方法应用于IEEE-33节点配电系统的支路故障情况并进行仿真实验.结果表明,在大型IEEE节点配电系统中,所提出方法具有较高的运算效率与较好的可行性,求解速度相比传统的配电网可靠性自恢复方法提升了近3倍,能够有效提升配电网的自恢复性能.

In order to solve the problem of reliability decline resulting from the lack of fast and effective recovery scheme when branch faults occur in distribution network,a reliability self-recovery method based on branch grouping algorithm(BGA)for distribution network was proposed.According to the distribution network structure,the as-proposed method was applied to the branch faults of IEEE-33 node system,and simulation experiments were carried out.The results show that the as-proposed method has higher operation efficiency and better feasibility in large-scale IEEE node system,and the solution speed is nearly three times higher than that of the traditional reliability self-recovery method for the distribution network,effectively improving the self-recovery performance of distribution network.
