Abstract : The accurate estimation of power system frequency and amplitude is essential for power system monitoring, stability, control, and protection. This work proposes a novel approach for power system frequency and amplitude estimation based on variational mode decomposition (VMD) algorithm and Cheb-function (Chebfun) approximation system. In this work, the spectral information of power signals is extracted using VMD as sub-signals or modes. Each mode is further interpolated by Chebyshev polynomials in continuous domain using Chebfun system. The instantaneous frequency and amplitude are estimated based on zero crossings and local extrema locations of the continuous function. The robustness of the approach is evaluated on various power system scenarios and the results are compared with other existing methods. The promising results suggest that the proposed approach can be used as an efficient candidate for power system frequency and amplitude estimation.
