Model Predictive Control of Grid-Connected Power Converters with LCL Filter and Additional Feedback

Piotr Falkowski

Abstract

The benefits of using LCL filter connecting the grid with converter heavily depends on control method. Researchers in field of predictive control are mainly focused on improved the response dynamics, stability and accuracy of reference current tracking. This paper introduces an extended predictive control scheme of power converter with an LCL filter with improved operation under grid distortions. The proposed modification of control algorithm uses additional feedback form grid current to increase robustness for higher harmonics in grid voltage. The simulation results have proven good performance and verified the validity of the proposed solution. The laboratory test setup provided experimental results showing properties of the described method.
