“…The authors in [18] explored the possibility of decoupling the speed control machine from the grid frequency, in the case of a variable speed synchronous compensator based on wound rotor induction machine. The methods and results of more recent papers [19][20][21][22][23] are compared with those obtained in this article in the Section 4.3.…”

“…Focusing more on the protection of the electric machine in scenarios where high currents are flowing in the DFIG rotor circuit, such as voltage sag scenarios, Chowdhury and Chowdhury [22] introduced a method for compensation used to sink 50% of the voltage and voltage interruption, which prevents the isolation of the DFIG from the grid and guarantees the protection of the machine. The method uses a three-phase inverter that converts the DC voltage of a battery energy storage system.…”

Currently, power quality is a major issue for all sorts of customers. End users of the electricity service in industrial, commercial and residential sectors have nonlinear loads or loads that are sensitive to disturbances in the electric power supply. In this context, this paper presents a study on four different control strategies for the application of synchronous compensator based on a doubly-fed induction generator (DFIG). The mathematical modeling developed to support the proposal of this article is validated through computational simulations and experimental results. This work contains strong arguments that support the idea that the proposed synchronous compensator can be employed to cancel oscillations caused by imbalances in the grid, and can furthermore inject or absorb reactive and active power without the characteristic oscillations that arise when negative sequence components are present in the system.
