Problems solved by technology

[0006] (3) The window air conditioner is easy to install and cheap, suitable for small rooms, but the disadvantage is that it is noisy
The current demand response control technology for residential air conditioners is mostly focused on simple switch control, and the quantitative analysis of the impact of demand response on the power distribution side is not very sufficient

Embodiment 1

[0046] In order to realize the quantitative evaluation of the effect of demand response, and to have a better guiding value for the power system’s peak-shaving and valley-filling and saving electricity price expenditures of power users, the embodiment of the present invention provides a residential air-conditioning electricity price demand response strategy and its impact on For the control method of the impact on the power distribution side, see figure 1 , the method includes the following steps:

[0047] 101: Aggregate the mathematical model of a single air conditioner into an air conditioner load group, change the temperature set point of a single air conditioner in the response group, change the power consumption of a single device, and adjust the power of the device cluster;

[0048] 102: Return the bidding price of the air-conditioning load to the electricity market for auction and obtain the market-clearing electricity price, and pass the clearing electricity price to t...

Embodiment 2

[0061] Combine below Figure 1-Figure 4 , the specific calculation formula further introduces the scheme in embodiment 1, see the following description for details:

[0064] The ETP (Equivalent Thermodynamic Parameters) model is used to describe the thermodynamic dynamic process of residential air conditioners. The ETP model takes into account the heat exchange process between outdoor air and indoor air, indoor substances and indoor air, and uses heat capacity and thermal resistance to represent the heat exchange process. losses and thermal energy storage.

Embodiment 3

[0108] Combine below Figure 5-Figure 7 , carry out feasibility verification to the scheme in embodiment 1 and 2, see the following description for details:

[0109] Figure 5-Figure 7 It reflects the air-conditioning temperature set point, indoor temperature and feeder injected active power under the two scenarios of implementing and not implementing the residential air-conditioning demand response strategy.

[0110] That is, no demand response control is called no electricity price control, and the implementation of demand response control based on real time price (real time price, RTP) is called RTP control. Figure 5-Figure 7 It can be seen from the results that after the implementation of the residential air-conditioning demand response strategy, the temperature setting value of the residential air-conditioning has increased, and the room temperature has also increased. The impact on user comfort is relatively small.

[0111] After the implementation of the residential...

Abstract

The invention discloses a control method for a resident air conditioner demand response strategy and the influence thereof on distribution and consumption sides, comprising the steps of: aggregating mathematical models of single air conditioners into an air conditioner load group, changing a temperature set point of a single air conditioner device in the response group, changing the power consumption of the single device and adjusting the power of the device group; returning the bid price of the air conditioner load to an electricity market for auctions and obtaining a market clearing price, and transmitting the clearing price to a user side, and readjusting, by the user side, the temperature set point of the air conditioner by adopting the resident air conditioner demand response strategyaccording to the clearing price; and analyzing and controlling the influence on the distribution and consumption sides based on the resident air conditioner demand response strategy in combination with the percentage of temperature overrun time and the injected active power reduction percentage of a power system. The method introduces a linearized interactive demand response strategy of residentair conditioners for real-time electricity price signals, and expresses the temperature set points as a function of electricity price, thereby realizing the control on a single air conditioner temperature set point in the resident air conditioner group.

Description

technical field [0001] The present invention relates to the demand response control of clustered residential air conditioners, and the field of analysis and evaluation of the interactive impact of power distribution and consumption based on demand response, in particular to a demand response strategy for residential air conditioners and a control method for its impact on the power distribution and consumption side. Background technique [0002] In recent years, air conditioners have become one of the indispensable household appliances for urban residents, which generally include: cold source / heat source equipment, cold and hot medium transmission and distribution systems, terminal devices and other auxiliary equipment. Among them, the terminal device uses the cold and heat from the transmission and distribution to process the air and temperature, so that the air parameters of the target environment meet the requirements. [0003] There are many types of household air conditi...
