Abstract

The paper presents a nonlinear control of shunt active power filter operating in presence of nonlinear loads. The said filter is connected to PV system in order to deliver the active power to load. The main control objectives are: (i) compensation of harmonic currents and the reactive power caused by the nonlinear load; (ii) regulation the DC bus voltage of inverter. The control problem is dealt with a nonlinear controller that is developed by using the Lyapunov technique to cope with the harmonic’s issue. The outer-loop regulates the DC bus voltage of the static converter. The controller performances are validated by simulation in MATLAB\\Simulink.
