Abstract

Abstract : This study deals with a single‐stage photovoltaic (PV) grid‐tied system along with enhanced momentum least mean square (EMLMS) control algorithm, which extracts the fundamental components from the non‐linear load currents. Three‐phase voltage‐source converter with the EMLMS technique, feeds the solar PV power into the grid. Moreover, it is used to reduce the harmonics, load unbalancing and it compensates the reactive power to achieve the unity power factor of the grid currents. Moreover, this control provides the good dynamic response and fast convergence speed with less steady‐state error. The main objective of this control algorithm is to provide the sinusoidal and balanced grid currents under steady‐state and dynamic conditions. Test results of EMLMS technique are validated on a developed laboratory prototype.
