Thermostatic Load Control for System Frequency Regulation Considering Daily Demand Profile and Progressive Recovery

摘要: Large-scale wind and solar power integration are likely to cause a short-term mismatch between generation load demand because of the intermittent nature renewables. System frequency is therefore challenged. In recent years, it has been proposed that part residential can be controlled for regulation with little impact on customer comfort. This paper proposes thermostatic control strategy primary secondary regulation, in particular, using heating, ventilation, air-conditioning units electric water heaters. First, daily profile modeling indicates these two loads complementary daytime provide relatively stable reserve. Second, progressive recovery specifically considered scheme. The random switching cycle method mitigating rebound after air conditioners again. organize large population provision Consequently, requirement spinning reserve reduced. Finally, verified by dynamic simulation IEEE RTS 24-bus system.
