同步电力系统的系统频率随供电能量和用电能量的不平衡而变化。当大型发电机组丢失时，系统会经历相对于损失大小的频率摆动。使用频率响应设备限制系统频率的任何偏差。在过去的10年里，英国输电系统的发电组合发生了变化。这影响了频率响应服务合同的机器类型。未来风力涡轮机水平的增加也将影响系统的运行特性，并需要进行调查。一个过程，以优化响应要求，同时保持频率偏差的法定限制已经制定。这种方法需要合适的负荷和发电机模型来复制传输系统的性能。针对历史损失事件对整个系统的验证建立了对该方法的信心。通过动态模型对当前系统进行的审查表明，在某些情况下，利用CCGT工厂进行响应服务需要额外的主要响应。包括额外风力发电在内的模拟表明，在适当的情况下，未来有可能降低主要响应要求。在所有情况下都保持二级反应要求。
System frequency of a synchronous power system varies with the imbalance of energy supplied and the electrical energy consumed. When large generating blocks are lost, the system undergoes a frequency swing relative to the size of the loss. Any deviation in the system frequency is limited using frequency responsive plant. Changes have occurred to the generation mix of the British transmission system in the past 10 years. This has influenced the type of machines contracted for frequency response services. Future increased levels of wind turbines will also influence the operational characteristics of the system and warrant investigation. A process to optimise the response requirements while maintaining statutory limits on frequency deviation has been developed. This method requires suitable load and generator models to replicate transmission system performance. Validation of the complete system against historic loss events has established confidence in the method. A review of the current system with the dynamic model showed that utilising CCGT plant for responsive services requires additional primary response in some cases. Simulations including extra wind generation have shown that under appropriate circumstances, there is a potential to reduce the primary response requirement in the future. The secondary response requirements are maintained in all cases.
