State-shift priority based progressive load control of residential HVAC units for frequency regulation

摘要: Abstract The high penetration combined with the intermittent nature of large-scale distributed generation challenges stability power systems. Recently, it has been proposed that thermostatically controlled loads, such as heating, ventilation and air conditioner (HVAC) can be to provide efficient effective frequency regulation (FR) service a minimum impact on consumers’ comfort compared costly conventional spinning reserve. This paper proposes progressive load control strategy which enables residential HVAC loads implement primary secondary regulation. In particular, state-shift priority approach is efficiently choose responsive avoid frequent activations control. A time based random recovery developed mitigate rebound after period. With strategy, aggregation units behave like synchronous generator FR service. As result, required reserve reduced. dynamic simulation results indicate reliable smooth quickly via priority.
