The invention discloses a demand response control method of a temperature control device, and relates to the field of intelligent power grid and user side demand response. The method comprises the steps of sequencing electric heating pump groups through temperature extending margin and normalized temperature extending margin according to a target signal; screening the electric heating pump groups performing response according to a response signal; adjusting the temperature setting value of the screened electric heating pump group body, namely, decreasing the temperature setting value of starting the electric heating pumps in the group in case of shedding load, and increasing the temperature setting value of stopping the electric heating pump in the group in case of increasing load, wherein the adjustment is the temperature extending margin value of the electric heating pumps performing response at the current time. The method is applicable to consumption of power fluctuation of distributed renewable energy sources such as wind power; the method is high in heat storage characteristics; the requirement of a user on comfort can be met while controlling the electric heating pumps; in addition, a heat energy storing device is used as a response resource for smoothing power, so that a novel technical way is provided for microgrid application containing the renewable energy sources.
Description
technical field [0001] The invention relates to the fields of smart grid and user-side demand response, in particular to a demand response control method for temperature control equipment. Background technique [0002] Demand response (Demand Response, DR) is an intelligent power consumption control technology that adjusts the user's power consumption mode or manages the user's power consumption load. It is generally divided into two ways: price-based and incentive-based. Among them, the incentive-based DR mainly refers to the mutual cooperation between the grid-side dispatching center, the marketing system, and the energy-saving service company. By formulating deterministic or time-varying energy contract policies, users are encouraged to change load consumption during the normal operation of the system. Or reduce the load in an emergency, so as to achieve the purpose of system operation optimization. Incentive-based DR includes direct load control (DirectLoadControl, DLC...
