| Abstract_FL | To avoid the over reliance of personal preferences on traditional regional distribution network evaluation and achieve reasonable,accurate attribute weights,this paper proposed a multiple index attribute preference learning based intelligent comprehensive evaluating method for distribution network.The proposed method established the distribution network comprehensive evaluation model under confidence criterion and score criterion,according to the attribute measure theory.Then,it pre-processed the intermediate value indexes by introducing numerical absolute deviation rate.Finally,based on the historical training samples of distribution network,the proposed method calculated the preference weights of indexes by employing supervised random weighted neural network learning model.The paper performed intelligent evaluation of test samples by using the distribution network comprehensive evaluation model and well-trained attribute preference weights.Compared with traditional AHP,PSO-SVM and RWN algorithms,the experimental result analysis demonstrates that the proposed method is feasible,effective and robust,which can achieve a reasonable and objective comprehensive evaluation of target distribution network,and has certain application value on regional distribution network evaluation. |
