【摘要】：配电网多故障抢修不只是优化故障抢修顺序的问题,多小队协同抢修时,故障任务的合理分配才是抢修工作顺利、高效完成的前提。本文同时考虑抢修小队初始位置不同及负荷本身故障,定义了抢修小队偏好、抢修小队能力向量和故障任务需求向量,然后基于属性向量建立了可解决小队协作问题的效用函数模型,形成效用函数矩阵;最后结合轮盘赌选择方法得到基于最优效用的故障任务分配方案集。采用属性向量的形式量化抢修信息,可以随时改变属性向量维数,解决抢修资源以及现场故障需求的不确定性问题,实现故障任务的动态分配。仿真结果给出了10种任务分配方案,并用改进的细菌群体趋药性(BCC)算法优化得到最优方案及最佳抢修顺序,验证了所提方法的有效性和正确性。
[Abstract]:Multi-fault repair in distribution network is not only the problem of optimizing the repair sequence, but also the reasonable allocation of fault tasks is the success of the emergency repair work. At the same time, considering the different initial position of the repair team and the failure of the load itself, this paper defines the predilection of the repair team, the capability vector of the repair team and the requirement vector of the fault task. Then, based on attribute vector, the utility function model is established to solve the problem of team cooperation, and the utility function matrix is formed. Finally, combined with roulette selection method, a fault task assignment scheme set based on optimal utility is obtained. The dimension of attribute vector can be changed at any time by using attribute vector to quantify the repair information. In order to solve the uncertain problem of emergency repair resource and field fault demand, the dynamic assignment of fault task is realized. The simulation results show that 10 kinds of task allocation schemes are given. The improved BCC algorithm is used to optimize the optimal scheme and the optimal repair sequence, which verifies the validity and correctness of the proposed method.
