本文研究了基于需求响应（DR）激活恒温控制负荷（TCL）的电力系统中提供二次频率控制，并量化了大TCL人口控制的计算资源约束。由于TCL是快速响应负载，它们代表了用于提供这种控制的常规源的合适替代方案。以国产电冰箱为代表的TCL在孤岛电力系统中进行了实验研究，以评估二次频率控制。该调查量化了家用冰箱性能在响应时间和上升速度方面的灵活性，以及控制期后对冰箱温度和行为的影响。实验结果表明，TCLs是DR激活的快速响应负载，平均控制信号响应时间为24 s，等效斜坡率为63%/min，也能满足一次频率控制的要求。
This paper studies the provision of secondary frequency control in electric power systems based on demand response (DR) activation on thermostatically controlled loads (TCLs) and quantifies the computation resource constraints for the control of large TCL population. Since TCLs are fast responsive loads, they represent a suitable alternative to conventional sources for providing such control. An experimental investigation with domestic fridges representing the TCLs was conducted in an islanded power system to evaluate the secondary frequency control. The investigation quantifies the flexibility of household fridge performance in terms of response time and ramp-up rate, as well as the impact on fridge temperature and behaviour after the control period. The experimental results show that TCLs are fast responsive loads for DR activation, with the average control signal response time of 24 s and an equivalent ramping rate of 63% per minute, which could also comply with the requirements for primary frequency control.
