Wind Farm Based DFIG Supervision In Case Of Power Gradient Constraint

In the last decade, the penetration of wind energy is increased into the network. However, the supervision of wind farms (WF) has evolved so as to follow the power gradient constraint reference requested by the transmission system operator (TSO). This algorithm is found on a central and a local supervisory: in the first one, a central supervisory unit that ensures the communication flow between the TSO and the WF. In the second a local supervisory unit that controls each wind turbine (WT) in accordance with the central unit, is demand. Simulation results will be presented to show the validity of the algorithm proposed that ensures the limitation of Power Gradient Constraint.
