A Normalized Adaptive Filter for Enhanced Optimal Operation of Grid-Interfaced PV System

This article presents a grid-connected single-stage photovoltaic (PV) system using an adaptive normalized notch filter (ANNF). An unknown time-varying fundamental frequency is precisely estimated from a normalized notch filter and consequently, the fundamental load component is extracted using this...
