The increasing penetration of modern Variable
Speed Wind Turbines (VSWTs) in microgrids creates the problem of frequency
stabilization due to reduced inertia of the power system. To emulate the Inertia
Response of the conventional synchronous machines, wind turbines can be
provided with an inertia emulation controller. The modelling presented in this
paper aims at equipping the modern Type D wind turbine with inertia response
and primary frequency control (PFC) capabilities. Two controllers — inertial
and droop, are implemented and their frequency control capabilities are
compared in an isolated power system which consists of a conventional steam
turbine generator and a wind farm. The results suggest that proposed
controllers help in better frequency control performance in the microgrid
