摘要
提出一种解决配网动态重构问题的静态方法。该法不仅求解简单,而且能充分利用现有的静态方法来实现时变系统的动态重构。首先,文章对静态重构的目标函数进行改进,使其能够求解一个时间区间内的最优结构。然后在整个时间区间内用枚举法确定最优的重构时间,完成区间内的一次动态重构。最后用逐次逼近法来调整各次重构的时间和结构,实现区间内的多次优化。在修改过的IEEE33节点上验证了所提方法的正确有效性。
A static method which can deal with distribution network dynamic reconfiguration is presented in this paper. The method not only can be realized easily, but also can make use of any established static method for solving dynamic reconfiguration. At first, objective function of static reconfiguration is amended for being applied in interval optimization. And then, time enumeration method is implemented for determining optimal reconfiguration time. Thus, once dynamic reconfiguration is finished. For realizing multi optimizations within specified time interval, gradual approaching method is employed for adjusting the time and frame of each reconfiguration. Correction and effectiveness of the proposed method is validated on modified IEEE 33-bus system at last.
