摘要：This paper presents a three-phase four-wire GridConnected Inverter with Model Predictive Control connected to a distribution Grid. The inverter functions as a filter for the harmonics caused by nonlinear loads, and this involves describing the harmonic currents using the dq0 transformation, after which the low pass filter’s implementation is changed back to dq0 and used as the reference current for the Model Predictive Control in the current process. Therefore, the reference current was compared with the modeled prediction current with the smallest difference found in different switching states further used to switch the IGBT on the three-phase four-wire Inverter. The test results showed the model has the ability to reduce the THD of harmonic currents formed from nonlinear loads, and the MPC control was observed to have a fast response to reduce harmonic currents under dynamic load conditions.
