Abstract :
This paper presents a discrete-time sliding-mode control of a VSC based STATCOM, intended for its application to wind farm connection to the grid. A sliding-mode controller has been used for currents while pole placement with a slower dynamic response has been used for DC bus voltage control, as DC voltage has been assumed to have slower dynamics than currents. Besides, the voltage and current limitations of the system has been studied and their influence analyzed by means of limitation circles
