Improvement of the Current Profile in Grid-Tied Hybrid Energy System by Three-Phase Shunt Active Filter

摘要

This is all about harmonic the current mitigation (as one of the major power quality issues) through the imaginary power owing to their precise and audacious action by shunt active filter (ShAF) build on sinusoidal current control strategy (SCCS) in a grid-tied PV system. The SCCS is employed to liberate sinusoidal current commenced from the supply additionally with a burly synchronizing (phase-locked loop) circuit, concise the controller for ShAF. Explicitly by a sinusoidal current control based controller, ShAF acts as a harmonic isolator amidst with load and supply. The performance of the said technique is evaluated using MATLAB R2016a under passive load (nonlinear load), and the observations are discussed. The efficacy of the ShAF in harmonics mitigation is validated through the proposed simulation. The total harmonic distortion (THD) of current and voltage ascertains controller's practicability for the ShAF delivering harmonic separation of passive loads in the grid-tied hybrid energy system.
