摘　　要：提出了一种区域电网无功功率/电压最优化控制的模糊负荷数学模型,其目的是在当前时段内各负荷值的情况下使功耗最小.该模型利用[DW]分离划分为4个小问题,各小问题再经过[DW]分离划分为若干范围,降低了问题计算的复杂度.通过实例验证了该模型的有效性.A novel mathematical model of fuzzy load is presented for optimal reactive power/voltage control of large-scale electric networks. The objective is to minimize power losses considering various load conditions, at the current interval. The problem is decomposed into four sub-problems via the Dantzig-Wolfe decomposition for reducing the dimensions of the problem. A second Dantzig-Wolfe decomposition divides each sub-problem into several areas leading to a considerable reduction in the dimensions of sub-problem. We illustrate the validity of the model with an instance.
