Voltage Oriented Control of Three Phase Bidirectional AC/DC Converter

This paper describes a famous control strategy dedicated to the three-phase bidirectional AC/DC converter called Voltage Oriented Control (VOC). The proposed technique is based on measuring the voltages and currents of the electrical grid in a first phase. Then, the decoupling between the direct current component and the quadrature component of the current, obtained via the Park transform (d–q), will be ensured by what is called feed-forward flow control. The latter is equivalent to using PI controllers. Finally, in order to establish the desired performances, the simulation will be visualized by the Matlab/ Simulink environment.
