Voltage division control in AC / DC hybrid distribution network based on model predictive control

Due to the uncertainty and low forecast accuracy of the distributed generation output, the traditional voltage control method is facing big challenges. This paper presents a novel three-phase reactive power and voltage distributed control method of AC/DC hybrid active distribution network based on model predictive control. This method uses model predictive control theory to deal with uncertainty of the distributed generation output, uses distributed control theory to deal with long computation time of the large-scale grid and three-phase mathematical models to deal with unbalance of three-phase voltage in distribution network. The proposed method is test on an AC/DC hybrid distribution system. The simulation results proved the validity of the model predictive control and the rapidity of the distributed control.
