Title: Extreme Learning approach for Power Quality Event Classification
Abstract: Monitoring Power Quality Events (PQE) is a crucial task for sustainable and resilient smart grids. This paper proposes a fast and accurate algorithm for monitoring PQEs from a pattern recognition perspective. The proposed method consists of two stages: feature extraction (FE) and decision-making. This seminar focuses on utilizing a histogram based method that can detect the majority of PQE classes while combining it with a Discrete Wavelet Transform (DWT) based technique that uses a multi-resolution analysis to boost its performance. Then, the proposed Extreme Learning Machine (ELM) is used to classify the Power Quality measurement data.
