Abstract: To address the issues of slow response speed, poor accuracy, and weak robustness of the traditional unified power quality conditioner, this study proposes a continuous control set model predictive control (CCS-MPC) direct control strategy that decouples control targets. The proposed control strategy constructs a unique prediction control model based on the current parameters of the controlled target voltage and current, achieving the decoupling control of the inductance current and the capacitance-voltage on both the series and parallel sides and enhancing the dynamic performance of the UPQC while effectively simplifying the structure of the controller. By obtaining the optimal solution of the value function through partial derivatives, the proposed control strategy achieves high precision compensation for changes in parameters and external disturbances such as load voltage and grid current. The effectiveness of the proposed control strategy is verified by simulation.
