IMPROVING THE QUALITY OF GRID-CONNECTED INVERTER BY SLIDING CONTROLLERS AND HYBRID FILTERS

Abstract

This paper presents the results of the synthesis of the sliding control unit
(SMC) for the grid-connected inverter system using a hybrid filter, a combination
of active power filter (APF) and passive power filter (PPF). The controller has
helped to reduce the influence of nonlinear loads and harmonics on the stability
of the grid. The quality of the proposed controller and filter is evaluated through
simulation results using Matlab-Simulink software.
