ELM算法在用户用电行为分析中的应用

Application of ELM Algorithm in the Analysis of Customer Electrical Behavior

对于非法用电行为的检测,电力企业通常采用传统的人工检查方式,而这种方式的准确率和效率往往都比较低.提出一种将极限学习机(ELM)应用于预测存在非法用电行为用户的方法.首先,在收集到的用户历史用电数据,对原始数据进行预处理.然后,应用ELM算法建立异常用电行为的神经网络模型.最后,在真实用电数据上进行实证分析,通过与随机森林算法建立的预测模型及预测结果的对比,证明提出的方法具有较高的准确率和较好的性能.

In order to detect the illegal use of electricity, electrical enterprises generally adopt traditional manual examination ways. However, both of the accuracy and efficiency of the approaches are far from satisfaction. In this paper, an analysis method based on the Extreme Learning Machine（ELM） algorithm is proposed, which is used to predict the behavior of customers＇ illegal electric use. Firstly, it collects the historical electric usage data and preprocesses the data to make it suitable for analysis by the algorithms. Then, it applys an algorithm based on neural network model, which is called ELM, to build the model to describe the abnormal power utilization behavior of the customers. Finally, experiments on the real electrical consumption data are conducted to evaluate the proposed method. The experimental results demonstrate that the proposed method is accurate and efficient.
