由于发电组合的变化，GB电网的惯性下降，对未来电力系统的运行和控制提出了挑战。这项工作分析了风力涡轮机发电机的惯性贡献的GB电力系统和测试的有效性的辅助控制器设计提供惯性支持作为辅助服务。一个简化的三机表示的GB电网纳入变速风力涡轮机已开发进行频率研究。这些机器代表了英格兰、威尔士和苏格兰的电力系统。针对不同的风电穿透水平，分析了风电机组的频率支持能力。风速和辅助惯性控制器的影响也进行了评估。为了完整起见，将有和没有频率控制的系统响应与仅具有传统同步发电的等效系统进行比较。
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.
