Requirement response control method for household temperature control load

Abstract

The invention discloses a requirement response control method for a household temperature control load, which comprises the following steps: acquiring adjusted temperature in a real-time manner and on-off state and rated power of controllable temperature-controlled equipment, building a functional relationship of the state between the controllable variable and the temperature-controlled equipment, which can reflect the grid running state; according to the functional relationship of the state between the controllable variable and the temperature-controlled equipment and the temperature controllable range of the temperature-controlled temperature, obtaining the upper and lower bounds describing the adjusting ability of polymerization load group of a plurality of temperature-controlled equipment; based on the upper and lower bounds in the last step, ensuring a response target PHP*[t+Delta t], and calculating the target on-off state of temperature-controlled equipment in the next step; after the completion of temperature temperature-controlled response, obtaining a practical overall response load value PHP [t+Delta t] of all temperature-controlled equipment at the time of t+Delta t. According to the invention, effective description reflects user-comfortable using information or operation restraint on individual temperature-controlled equipment, so as to monitor the adjusting range of the load on the temperature-controlled equipment. Moreover, the method is helpful to reducing electric power system operation and construction cost, and meets various demands in practical application.

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 household temperature control loads (electric heat pumps and refrigerators, etc.). Background technique [0002] Demand response technology refers to the technical means of effectively controlling a large number of load equipment distributed on the demand side through power prices or other incentives, and through its automatic response to achieve the goal of system load regulation. Household temperature control equipment (such as electric heat pumps, water heaters, and refrigerators, etc.) is one of the important adjustable load resources. How to effectively control the switching status of home temperature control equipment in real time through demand response strategies, so that a certain number of home temperature control equipment responds to the load adjustment target of the system, and effectively participates in p...

Problems solved by technology

[0004] At present, most researchers mainly discuss the demand response method of home temperature control equipment. There is insufficient modeling information on the range of response load adjustment capability of home temperature control equipment and the limitation information of users' comfortable use, and it is impossible to effectively quantify the range of its adjustment capability. Dynamic monitoring will lead to increased grid control costs and higher system maintenance costs
