The declining inertia on the GB grid as a result of the change in the generation mix poses a challenge in the operation and control of the future power system. This work analyses the inertia contribution of wind turbine generators to the GB power system and tests the effectiveness of supplementary controllers designed to provide inertia support as an ancillary service. A simplified three-machine representation of the GB grid incorporating variable-speed wind turbines has been developed to carry out frequency studies. The machines represent the power system of England, Wales and Scotland. The frequency support capability of the wind turbines is analysed for different wind power penetration levels. The impact of wind speed and of supplementary inertia controllers are also assessed. For completeness, the system response with and without frequency control is compared with an equivalent system featuring conventional synchronous generation only.
