Air-conditioning load reduction method based on temperature adjustment means and SOC (State of Charge) parameter modeling

Abstract

The invention provides an air-conditioning load reduction method based on temperature adjustment means and SOC parameter modeling. The method comprises the following steps that S1) an air conditioningload-room temperature basic model is established; S2) an air conditioner is virtualized into an energy storage component, a concept of SOC parameter is introduced, and a charge parameter energy-storage model of the air conditioning component based on the SOC parameter is established; S3) an air-conditioning load reduction model based on the temperature adjustment means and SOC parameter modelingis established; and S4) when there is capacity lack in the power grid in summer, an air conditioning load which is expected to be reduced is input to the air-conditioning load reduction model, and indoor temperature upper/lower limit, load reduction lasting time and advanced cooling time prescribed by air-conditioning load reduction control are determined, and the maximal value that can be reducedof the air conditioning load is calculated. Thus, the power grid load can be reduced without influencing the comfortableness of users.

Description

technical field [0001] The invention relates to the field of electric power system automation, in particular to a method for reducing air-conditioning loads when the grid load is heavy in summer. Background technique [0002] In recent years, the proportion of air-conditioning load in the total power load has been increasing, which has directly led to new highs in summer load and aggravated peak-to-valley differences. In order to solve this problem, the method of adjusting the unit output from the source side will increase the loss of the generator, and the reserve capacity will be wasted due to too little use time. Therefore, the regulation technology of the load side has received extensive attention. At present, there is no effective modeling method for air-conditioning load, and the control method often uses interruptible control to directly shut down. Since the cooling capacity generated by the air conditioner can be stored in the building and maintained for a period of...
