摘要
To improve power quality of power grids, a unified power quality conditioner (UPQC) based on model predictive control (MPC) is proposed. The basic principle and structure of UPQC are presented and a model of UPQC is built to attain its state-space model; based on the state-space model, the MPC control algorithm is applied in UPQC, then an MPC controller is designed. Simulation results show that the MPC-based UPQC can effectively compensate harmonic distortions and interferences can be suppressed.
