ABSTRACT: The paper examines two major implementations of inertial response in variable-speed wind turbine generators. Through time-domain simulations, these supplementary loops are compared based on their impact on grid frequency and the wind plant. Testing is performed on an isolated, hydrodominated power system benchmark, to which a DFIG-based wind plant is connected. The results show that when these implementations are combined, with proper coordination, the resulting controller is capable of superior performance.
