Abstract

In this paper, a new variable step size least mean square adaptive filter-based control algorithm is proposed to generate reference current for voltage source converter of a grid-integrated PV system. The proposed control generates reference current by extracting the fundamental active and reactive component from load current with fast convergence. The proposed control offers better initial transients and dynamic performance than conventional LMS and synchronous reference frame-based control. Grid-integrated PV system is modelled in MATLAB/Simulink and is tested on different loading condition viz. nonlinear load, unbalanced load and variable load. Further, to validate the efficacy of the proposed control, it is also tested in real time on prototype hardware in the laboratory. It has been observed that proposed control provides compensation of harmonic and reactive power of the local load. Distortion at grid side of the system is within the limits as per IEEE-519 standard.
