【Abstract】 The paper presents a new mathematical model for the optimization of transformer capacity,conductor size,number of transformers and substations in consideration of the characteristics of distribution system. This model can be used to establish the principles of network planning.In the model the objective function includes all the costs of the distribution systems. The genetic algorithm is used to minimize the objective function considering the technical constraints.The results of a computational example show that the method is effective.更多还原
