【Abstract】 The direct current load flow model is broadly applied in the static security analysis in power system because it is simple and easy to calculate rapidly. Unfortunately, it is not so satisfied because of its low precision. One kind of improved direct current load flow model is put forward to improve its precision in the paper. The proposed approach was tested on the standard IEEE14 bus and IEEE30 bus system. The results of simulation show that the method is effective.更多还原
