In this paper, we present a new automatic transient detection and localization for analysis of power quality disturbances. The proposed method is based on an over-complete dictionary (OCD) matrix and an ℓ1-norm minimization algorithm. The OCD matrix is constructed using the spike-like (or identity) bases and discrete-cosine bases. The proposed method is… CONTINUE READING
