A central air-conditioning cluster control method, system and equipment

Abstract

The invention discloses a central air-conditioning cluster control method, system and equipment, comprising: establishing a theoretical model of the power of a single central air-conditioning, performing parameter identification on the theoretical model of the power of a single central air-conditioning, and obtaining an identification result; establishing a single central air-conditioning The error model of theoretical power and actual power; form the bidding information of the central air-conditioning cluster and set the temperature T setc (t); Generate the n of the power error of each central air conditioner s In this scenario, a stochastic programming model is generated to regulate the power of the central air-conditioning cluster. The present invention avoids the selection of meaningless parameters by performing parameter identification on the power theoretical model of a single central air conditioner, and realizes accurate modeling. The control method is to adjust the set temperature of each central air conditioner, and through the bidding information of the central air conditioner cluster, Realize the rapid calculation of the set temperature range of the central air-conditioning cluster, and the stochastic programming model accurately tracks the target curve through the power consumption curve of the central air-conditioning cluster, and realizes the precise regulation of the central air-conditioning cluster.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning control, in particular to a central air-conditioning cluster control method, system and equipment. Background technique [0002] In recent years, demand response has been practiced on a large scale in countries all over the world. It has the functions of shaving peaks and filling valleys, improving the operating efficiency of power systems, and promoting the consumption of renewable energy. Central air-conditioning is a typical demand-response resource. Because small-scale changes in indoor temperature have little impact on human comfort, regulating central air-conditioning clusters can reduce or increase a large amount of power. Therefore, the central air-conditioning cluster control strategy applicable to various power system scenarios (such as peak load shifting, renewable energy consumption, etc.) has become a subject that needs to be studied. In the existing research, the ce...
