Aiming at the classification problem of electricity consumption analysis of smart users under the background of big data

a classification method based on extreme learning machine(ELM)algorithm is proposed for electricity consumption behavior analysis. Firstly

based on the previous research of feature preference for electricity consumption behavior of smart users

the feature preference strategy is adopted to extract the best feature sets of the load curve

which helps to classify and analyze the data of electricity consumption for users. Then

the best feature sets are used as the input of ELM network. By comparing the accuracy of the training set and the test set with different hidden layer excitation functions and hidden layer node numbers

input parameters of ELM algorithm are selected

which are suitable for user's electricity consumption behavior analysis. Finally

the domestic and foreign electricity consumption data is taken as the data source to carry out the simulation experiment. Through the comparison and analysis with back propagation(BP)neural network

the results show that the analysis of electricity consumption behavior based on ELM algorithm improves the detection accuracy and reduces the algorithm operation time

which can better grasp the user load status and realize load balance of distribution network.
