A Variable Droop Frequency Control Strategy for Wind Farms that Considers Optimal Rotor Kinetic Energy [PDF]

IEEE Access, 2019
A variable droop control strategy for wind farms (WFs) that considers optimal rotor kinetic energy (RKE) is presented in this paper. The process for the control strategy is as follows. First, an optimized scheduling reserve mode (OSRM) is executed by the WF control center (WFCC) according to the deloaded rate orders issued by the dispatching center ...
