Fast Automated Demand Response (FastADR) is one of the expected measures to control electricity demand of consumers so that the balancing of electricity supply and demand in a short time horizon is improved. Due to their high power consumption in business buildings, Heating Ventilation and Air-conditioning (HVAC) loads are the promising resource for FastADR. However, because of their operational characteristics, HVAC loads do not perfectly follow external control signals. To mitigate this problem, Battery Energy Storage System (BESS) can be used complementarily. This paper proposes a method that coordinates the operation of building’s multi-units air conditioning system and BESS to reduce the required capacity of BESS for supporting HVAC operation in the FastADR. In the proposed method, the BESS discharges to supply the difference between the FastADR signal and HVAC load consumption and then recovers its energy by further adjusting the reference power consumption of the HVAC load, in which the thermal capacity of buildings is considered to reduce the required capacity of the BESS. Numerical simulations are performed to demonstrate the benefit of the proposed coordinated control.
