Abstract
A lot of techniques based on active power filter have been proposed in many transmission and distribution networks for harmonic mitigation. However, this does not come easy as it may involve a chain of cascaded structures coupled with large computational data, which consequently affects the response of the control system. In this paper, model predictive control (MPC) strategy based on active power filter (APF) is proposed to accomplish the real-time and accurate harmonic current compensation in the power systems. In MPC strategy, the future behaviour of the controlled variables is predicted using the model of the system. The cascaded structure usually applied in linear control system is avoided, giving rise to a fast response. Verification of the effectiveness and validity of the proposed method are demonstrated by the simulation results using MATLAB/Simulink tools. The results show a significant reduction in the Total Harmonic Distortion (THD) when sampling time is varied.
