| Abstract: | 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. |
