Problems solved by technology

The advantage of the conventional aggregation control method is that it can quickly and accurately reduce the load, but this method of directly cutting off the power supply is very unfriendly to the user, and it is difficult to persuade the user, especially the residential user, to participate in this regulation, so difficult to promote
In addition, another obvious shortcoming of the conventional aggregation control method is load rebound, that is, for a period of time after the regulation ends, the air-conditioning aggregate will have a power value that is several times larger than before the regulation, which brings a new burden to the power grid

Embodiment Construction

[0046] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced.

[0047] The process of building and solving a complete power model is as follows: figure 1 shown. The house / building model can be divided into the structure of the house and the electrical equipment inside the house. The structure of the house includes the size of the house, the area of ​​the exterior walls, the area of ​​the windows, etc. Usually, the house model is often established by using an equivalent thermal parameter model (Equivalent Thermal Parameter, ETP), that is, a DC circuit described by several centralized parameters using an almost parallel heat flow path. Such simple processing is beneficial to the operation and calculation of large-scale residential models. Under the laws of physics, temperature, conductance, thermal energy, and heat flow are equated with voltage, conductance, capacitan...

Abstract

The invention provides an air conditioning system polymerization control method. The method comprises the steps that by simulating an air conditioning system in a real scene, an air conditioning system polymer model is established, and system parameters of each equivalent thermal parameter (ETP) model are assigned; according to a load objective and load constraint conditions of the air conditioning system polymer model, a plurality of sets of temperature target values in preset time are generated; the work change amount required by each air conditioner is computed, and the work change amount of the air conditioning system polymer model in preset time is computed according to the work change amount required by each air conditioner; and the temperature target value corresponding to the workchange amount meeting the load objective and the load constraint conditions is used as the temperature of the air conditioning system, simulated by the air conditioning system polymer model, in the real scene, and the load of the air conditioning system in the real scene is controlled through temperature adjustment. Through the method, load rebound caused by adoption of polymer control can be greatly reduced while the air conditioner load participates in system demand side response.

Description

technical field [0001] The present invention relates to the technical field of electric power systems, and in particular, to a method for controlling aggregation of an air conditioning system. Background technique [0002] Smart grid has become the trend of power system transformation in the 21st century. As a new type of intelligent service network, its communication capability has been greatly improved with the development of communication networks. As an important part of smart grid, smart electricity consumption is to connect the flexible power network and information network to form an efficient and complete electricity information service system and service platform, and to construct the power flow and information between the power system and the electricity load. A new type of power supply and consumption relationship with real-time interaction of flow and business flow. By mobilizing electricity loads to participate in demand response, optimizing electricity consump...
