"Power run-back schemes are included in some wind farm installations. Power run-back allows the system operator to send a remote signal to instruct the wind farm to reduce active power with a certain minimum ramp down rate to a predetermined power level and to stay there until the run-back signal is cleared. These schemes can protect the power system against loss of thermal transfer capability or transient angle instability."
