Embodiment Construction

[0056] The present invention will be further described in detail below with reference to the accompanying drawings, which is an explanation but not a limitation of the present invention.

[0057] See figure 1 , A control method of air conditioning system considering demand response, including demand response daily operation strategy and non-demand response daily operation strategy;

[0058] The demand response day operation strategy includes the following steps:

[0059] 1) The temperature load parameters of the previous period of time are obtained through the data collection and storage module. The predicted parameters include the hourly cooling load of the building, outdoor meteorological parameters, indoor personnel hot backup and lighting load.

[0060] 2) According to the temperature load parameters combined with the BP neural network algorithm, predict the hourly cooling load of the building during the demand response period, (the external disturbance load ∑Q in the dynamic heat...

Abstract

The invention provides an air-conditioning system control method taking demand response into consideration and a refrigerating system. According to the energy storage features of a buffering water tank, strategies for running in non-demand response days and strategies for running in demand response days are made through the buffering water tank within the user acceptable heat comfort range of an air-conditioning room, demand response allowance is acquired for air conditioner users while stable demand response auxiliary services are provided for a power grid, and the flexibility and economicalefficiency of energy consumption of an air-conditioning system are effectively improved; and in the strategies, the role played by the buffering water tank running under the designed load of the air-conditioning system is taken into consideration, and thus the air-conditioning system can effectively utilize the energy. In addition, the running cost of the air-conditioning system can be effectivelyreduced by regulating and controlling the buffering water tank based on peak and valley electric prices.

Description

Technical field [0001] The invention relates to a control technology of an air conditioning system in a power plant, in particular to a control method and a refrigeration system of an air conditioning system considering demand response. Background technique [0002] As the main source of electricity consumption in cities, the increasing power consumption of buildings has become one of the important reasons affecting the imbalance between supply and demand in the power grid. In particular, the increased power consumption of the air-conditioning system in the winter and summer due to the heating and cooling requirements of the building has caused the power grid to appear peaks in the winter and summer. Because the heating and cooling demand fluctuates greatly due to the influence of outdoor temperature, the time period during which the temperature control electricity load generated by air conditioning is at the peak is usually shorter. The power grid has shorter daily electricity p...
