DESIGN SLIDING CONTROLLER FOR GRID-CONNECTED INVERTERS USING LCL FILTER

Abstract

This paper presents and proposes some solutions to improve the control quality of grid-connected inverters. The direct power control method uses an external voltage loop design to ensure the stability of the voltage bus as well as obtain the reference value of the internal current loop. Design of internal current loop slip controller to ensure grid current and effective anti-interference. The entire control system is tested through simulation with Matlab/Simulink software.
