摘要
Abstract
Due to the deficiency of control of the grid-connected inverter by the conventional method, therefore, this paper proposed a model predictive control ( MPC) method. The predictive control by this model predicts the active power and reactive power at the next moment. Finally, the voltage vector with the smallest value function is selected to act on the switch tube. The switch tube acts on the inverter to achieve grid-connection control. The effectiveness of this method was verified by building a MATLAB/Simulink simulation model and comparing it with traditional control methods. The simulation analysis results show that the control method can track the changes of active power and reactive power. And the harmonic distortion rate is relatively low. That satisfies gridconnection and realizes reactive power compensation, and has good dynamic steady state performance.关键词
