This paper presents an approach to estimate voltage flicker components magnitudes and frequencies. The approach is based on L-p norms (p = 1, 2 and infinity) and Taylor series linearization. Effects of sampling frequency, number of samples, time interval, and noise are introduced. The main result is that it is possible to design an L-p estimator to identify flicker frequency and amplitude from time series measurements.
