Research on Three-Phase Grid-Connected Inverter Model Predictive Control

摘要

This paper presents a method of three-phase grid-connected inverter model predictive control (MPC) for the shortcomings of slow dynamic response and poor robustness of three-phase grid-connected inverters. Through MPC prediction, the optimal control quantity is obtained based on the optimization function. The establishment and implementation process of the MPC algorithm are introduced. The corresponding simulation model is established in Matlab/Simulink environment. The simulation results show that the MPC has the characteristics of fast dynamic response and strong robustness. It has good steady-state performance and is suitable for high-performance control of three-phase grid-connected inverters.
