Abstract

Grid-tied voltage source inverters (VSIs) with LCL filters are a promising solution for transmitting renewable energy to the grid, but they have a high tendency to resonance. To address this issue, various control techniques have been explored. This study proposes a sliding mode control with proportional resonant (PR) control for LCL grid-tied inverters (GTIs). A PR controller is used to generate the reference capacitor voltage, eliminating the need for a derivative operation that is not always preferred in control methodologies. A sliding mode observer is also proposed to reduce sensor requirements and enhance system stability. The proposed method is evaluated for an inverter connected to an unbalanced network experiencing voltage fluctuations, s well, and sag. The effectiveness of the method is demonstrated through simulation using Matlab/Simulink.
