Dynamic Harmonic Estimation Using a Novel Robust Filtering Strategy: Iterated Sliding Innovation Cubature Filter

Active filters (AFs) are effective tools for mitigating the detrimental effects of harmonic components on the power systems. The performance of AFs is significantly dependent on designing an accurate and robust estimator which is responsible for providing reference harmonic values. In this article, a novel technique, called sliding innovation (SI) cubature filter, is proposed to estimate the harmonic parameters, i.e., magnitude and phase, in …
