Embodiment

[0219] Taking a virtual demand response market area as an example, there is a total load of 40MW, of which the total load of the central air conditioner is 10MV, which is 100 units of 10kW air conditioners, divided into 10 groups, each group has ten units, and the operating status of the same group of air conditioners is the same. The parameters refer to the industrial practice experience value. The load curve of a certain day in summer is obtained as Figure 4 shown. In the 10 groups, select the main control variable data and load conditions of the air conditioning group 1-3 from 14:00 to 14:30 as shown in Table 1.

Abstract

The invention discloses a central air-conditioning modeling and controlling strategy on the basis of demand response, which comprises the following steps of building a room model, namely the relation between the indoor temperature and outdoor temperature of the room and sensible heat cooling load; building a center air-conditioning model suitable for the system operation of the demand response, namely the relation between air conditioning load and a decision variable; determining a controlling strategy, namely making an objective function, a control variable, a constraint condition and the like clear; solving the objective function by adopting a harmony search algorithm combining with a state space truncation method; obtaining a result, and performing analysis and treatment on the result. According to the central air-conditioning modeling and controlling strategy on the basis of the demand response, through meticulously building the models, making the strategy of multiple control variables cooperative optimization clear, scientific theoretical support is provided for the central air-conditioning to participate in the system operation of the demand response.

Description

technical field [0001] The invention relates to an electric power system and its automation technology, in particular to a modeling and control strategy for a central air conditioner participating in demand response. Background technique [0002] A few days ago, my country's electricity supply and demand may still be in a tense state. Demand response technology is the key to solving this contradiction. It can enhance the system's ability to cope with power flow fluctuations, improve system operating efficiency, and promote energy conservation and emission reduction. During the peak load period in summer, the air-conditioning load has accounted for 30%-40% of the peak load in the power grid, making the air-conditioning load the main research object for the application of demand response technology. The building environment to which the air-conditioning load belongs has a certain heat storage capacity, and the human body has no obvious discomfort within a certain temperature r...
