Application of Artificial Neural Networks and Wavelet Transform to Classify Advanced Power Quality Disturbances in Smart Grids

Power quality (PQ) is an essential branch of power system engineering. It plays a critical role in ensuring the quality of power being delivered to the customers. The emergence of smart grids highlights, even more, the importance of power quality. Currently, numerous devices capture the waveform of different disturbances in the electrical distribution network. However, most companies in this sector do not process this information or automatically classify these transients. This paper presents an identification scheme for the classification of PQ disturbances in electrical distribution systems using Discrete Wavelet Toolbox (DWT) and Artificial Neural Networks (ANNs). The software MATLAB/Simulink was used to model six PQ disturbances conditions, using reliable schemes to be consistent with what happens in real three-phase distribution systems. Three ANNs were  developed,  making  it  possible  to effectively  classify  the data set, even when a different input was inserted. Simulation results indicate that the proposed method for classification is robust, achieving high classification accuracy and adapting itself to different  conditions. All  MATLAB/Simulink models presented in this article have been uploaded to the authors' official Mathworks Central File Exchange.
