Grid voltage local regulation by a doubly fed induction generator–based wind turbine
(Sage journals, 2017) Kesraoui, Mohamed; Chaib, Ahmed; Bendaoui, Boujemaa; Achour, Djalloul
Voltage regulation at point of common coupling using a doubly fed induction generator–based wind energy conversion system is achieved through reactive power control. Wind energy conversion system produces reactive power when the voltage is less than grid nominal voltage and it consumes it in the opposite case. In this article, a method to achieve this goal is proposed. It consists of controlling the reference value of the vector control system in order to affect the wind energy conversion system reactive power output. Two situations have been simulated. Sudden voltage increase and decrease were applied to the control system. Satisfying results have been obtained since the voltage at point of common coupling has been restored back to its initial value
