Abstract:

Direct power control (DPC) has been proposed and well developed for its distinguished advantages such as simplicity, robustness, excellent steady-state and dynamic response. This paper presents a comparative study of DPC strategies of AC/DC converters for renewable energy generation. First, the advantages and disadvantages of each strategy are given by control theory investigation. In addition, virtual flux concept is studied and a voltage sensorless algorithm for SVM-based predictive DPC is proposed. Furthermore, steady-state and transient performance will be analyzed in simulation in terms of active and reactive power ripples, total distortion harmonic (THD) of line currents, sampling frequency, switching frequency tracking behavior, etc. Finally, a comprehensive comparison is drawn, based on which the most suitable strategy can be chosen according to different applications. © 2011 IEEE.
