[0043] in, is the comprehensive equivalent heat capacity of the virtual battery.

[0044] In one embodiment, when adjusting the indoor set temperature of the air conditioner and the set value of the air conditioner operating power according to the building heat balance model, the maximum power value that can be adjusted up and down and the optimal indoor set temperature value of the air conditioner can be automatically calculated by an algorithm with the goal of maximizing flexibility. Among them, flexibility refers to the ratio of the maximum power of the air conditioner that can be adjusted up and down to the operating power.

Due to power rebound during this period, the air conditioner can reduce the capacity to 0.

[0047] 3) Simultaneously adjust the indoor temperature and air conditioning power: During the time period from t1 to t2, during t 1-2 Always set the indoor temperature of the air conditioner from Adjust to ( > and ), and keep the operating power down to , the indoor air temperature is stable at T1±ΔT, and no alarm occurs during the use of the air conditioner, that is, the indoor air temperature does not exceed the upper limit of thermal comfort. During this period, the air conditioner can be adjusted down to .

[0048] 4) Control under comfort alarm: In the time period from t1 to t2, at t 1-2Always set the indoor temperature of the air conditioner from Adjust to ( and ), and keep the operating power down to , the indoor temperature continues to rise, and an alarm occurs during the use of the air conditioner, that is, the indoor air temperature exceeds the upper limit of the indoor comfortable temperature. This means that this solution cannot be implemented, and the air conditioner power needs to be increased until the thermal comfort requirements are met during the entire air conditioner use period.
