研究了家用热泵为电力系统提供动态频率响应的能力。开发了一个热模型来表示家庭热泵的人口。开发了一种分散的动态控制算法，使热泵能够根据系统频率改变其功耗。该控制算法保证了建筑物温度与电网频率之间的动态关系。热泵提供低频响应的有效性是根据Element Energy提供的数据得出的。案例研究通过将聚集热泵的代表性模型与英国国家电网开发的区域传输系统模型相连接进行。结果表明，分布在GB区域的动态控制热泵对GB系统频率有显著影响，并减少了对目前由昂贵的频率敏感发电机提供的频率服务的依赖。当系统惯性减小时，频率变化率也减小了。
The capability of domestic heat pumps to provide dynamic frequency response to an electric power system was investigated. A thermal model was developed to represent a population of domestic heat pumps. A decentralized dynamic control algorithm was developed, enabling the heat pumps to alter their power consumption in response to a system frequency. The control algorithm ensures a dynamic relationship between the temperature of building and grid frequency. The availability of heat pumps to provide low-frequency response was obtained based on data supplied by Element Energy. Case studies were carried out by connecting a representative model of the aggregated heat pumps to the regional Great Britain (GB) transmission system model, which was developed by National Grid. It was shown that the dynamically controlled heat pumps distributed over GB zones have a significant impact on the GB system frequency and reduce the dependency on frequency services that are currently supplied by expensive frequency-sensitive generators. The rate of change of frequency was also reduced when there is a reduction in system inertia.
