| Popis: | In the traditional power system, most of the frequency response services are provided from expensive large synchronous generators. However, demand is an effective element to provide frequency response with less expenditure. This paper discusses the availability of domestic heat pumps and fridges load to provide frequency response service to the Great Britain power system. The data of the low and high-frequency response from heat pumps is supplied by Element Energy while Open Energi provides data of the availability of fridges over the time of day. The potential of frequency response from the aggregation of heat pumps and fridges without undermining the inherent function of the load was estimated at a time of day. The combination of both loads to provide Firm Frequency Response (FFR) service was also investigated. Frequency control was developed to alter the power consumption of the aggregated load in response to a frequency signal. Simulation results showed that the aggregation of the load is an effective way to provide a dynamic frequency response over a day. |
