Primary Frequency Response in the Great Britain Power System from Dynamically Controlled Refrigerators
نویسندگان
چکیده
Primary frequency response from dynamically controlled refrigerators was investigated. A control algorithm was applied to a model of refrigerators to regulate their power consumption according to the deviation of system frequency. A model of a population of refrigerators equipped with such control was implemented in PowerFactory. A simplified Great Britain (GB) power system model was used to investigate primary frequency response from the refrigerators. Simulation results show that the refrigerators react effectively to the frequency variations by varying their power consumption.
