As shown in fig. 1, a flowchart of a control method for participating in power grid peak shaving in centralized heating by an air source heat pump provided in an embodiment of the present invention includes:
s100, acquiring indoor temperature of a user and heating equipment information, wherein the heating equipment information at least comprises the number of heating equipment and the heating quantity of the heating equipment.
In the step, the indoor temperature of the user and the information of the heat supply equipment are obtained, the indoor temperature of the user is the only index for judging whether the indoor temperature of the user reaches the standard, and the indoor temperature is regulated according to the urban heat supply service (GB/T33833-: under normal weather conditions, and when a heating system normally operates, a heating operation enterprise needs to ensure that the heating temperature in a bedroom and a living room of a heating user is not lower than 18 ℃, so in order to control the indoor temperature, the indoor temperature of the user needs to be obtained firstly, heating equipment information needs to be obtained secondly, the heating equipment information is an air source heat pump, for one air source heat pump, the power and the heating quantity of the air source heat pump need to be obtained, and the data are determined when the air source heat pump is in production; the heating quantity of the heating equipment is determined according to the air temperature.
