Non-intrusive Charging Identification Method for Electric Bicycles Based on Feature Selection and Incremental Learning
In order to monitor the illegal parking and charging behavior of electric bicycles from the grid side and reduce fire accidents caused by electric bicycle charging
on the basis of non-intrusive load identification
a charging identification method for electric bicycles is proposed based on feature selection and incremental learning. First
according to the measured current waveform of electric bicycle charging
this paper analyzes the load characteristics and lists 15 load features. The semi-supervised Fisher score and the maximal information coefficient are used to measure the feature discrimination and redundancy
and the greedy search algorithm is used to rank the importance of features. The feature subset with the highest identification accuracy is selected based on the ranking and identification results. Then
based on the incremental learning method for one-class support vector machine
the electric bicycle load identification and online learning of the classifier are realized. Finally
the experiment is carried out with actual measured data
and the results show that the proposed method can accurately identify the charging behavior of electric bicycles
which verifies the effectiveness of the algorithm.
