An innovative method using active filters for real time compensation of power line current distortions up to 5kHz is presented.  The method is based on the Wavelet Transform (WT), which offers more accurate time frequency resolution in comparison with Fast Fourier Transform (FFT). The WT also provides the flexibility of handling with either periodic or non-periodic signals, yielding to the detection in the time domain of all kinds of disturbs associated with renewable energy within a certain frequency range
