与频率控制相关的辅助服务在智能电网中的作用越来越重要。需求侧响应是可用于调节电网频率的竞争性资源。本文介绍了利用热泵和冰箱提供频率响应的辅助服务，使供应与需求不断平衡。家用机组的功耗通常较小，因此，大量小型机组的集合应能够提供足够的频率响应能力。在这项研究中，动态频率控制的开发，以评估能力，可以收集从家庭热泵和冰箱的频率响应的聚合。频率响应的潜力估计在冬季和夏季的特定时间。我们还调查了两个负载（家用热泵和冰箱）之间的关系，以提供固定的频率响应服务。对英国电力系统简化模型进行了实例研究。在此基础上，根据负荷的可用性，并考虑成本节约，模拟了三种负荷组合方案。结果表明，热泵和冰箱的集合提供了大的功率容量，因此，瞬时频率响应服务是可以实现的。最后，对采用聚合负荷的固频响应服务的经济效益进行了估算。
The role of ancillary services related to the frequency control have become increasingly important in the smart grids. Demand Side Response is a competitive resource that can be used to regulate the grid frequency. This paper describes the use of heat pumps and fridges to provide ancillary services of frequency response so that to continuously balance the supply with demand. The power consumption of domestic units is usually small and, therefore, the aggregation of large numbers of small units should be able to provide sufficient capacity for frequency response. In this research, dynamic frequency control was developed to evaluate the capacity that can be gathered from the aggregation of domestic heat pumps and fridges for frequency response. The potential of frequency response was estimated at a particular time during winter and summer days. We also investigated the relationship between both loads (domestic heat pumps and fridges) to provide Firm Frequency Response service. A case study on the simplified Great Britain power system model was developed. Based on this case study, three scenarios of load combination were simulated according to the availability of the load and considering cost savings. It was demonstrated that the aggregation of heat pumps and fridges offered large power capacity and, therefore, an instantaneous frequency response service was achievable. Finally, the economic benefit of using an aggregated load for Firm Frequency Response service was estimated.
