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 various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.

[0047] A complete power model construction and solution process is as follows: figure 1 shown. The house / building model can be divided into house structure and house internal electrical equipment. The structure of the house includes the size of the house, the area of ​​the outer wall, the area of ​​​​the windows, etc. Usually, the building model is often established by using the Equivalent Thermal Parameter model (Equivalent Thermal Parameter, ETP), which adopts an almost parallel heat flow path and describes a DC circuit with several lumped parameters. Such simplification 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 to voltage, conductance, capacitance, and current i...

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 invention relates to the technical field of power systems, in particular to an aggregation control method for 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 network. As an important part of the smart grid, smart electricity consumption is connected through a flexible power network and information network to form an efficient and complete power consumption information service system and service platform, and to build power flow and information between power systems and power loads. A new type of power supply and consumption relationship that interacts in real time with streams and business streams. By mobilizing power loads to participate in demand response, optimizing power consumption methods, and realizing reliable ...
