Air conditioning load control strategy making method based on direct load control

Abstract

The invention discloses an air conditioning load control strategy making method based on direct load control. According to the air conditioning load control strategy making method, a thermodynamic model of a single air conditioning unit is established and used for representing the relation among air conditioning power, temperature and time; an ideal in-turn control strategy for centralized control of air conditioning loads is analyzed according to the thermodynamic model of the single air conditioner unit and requirements of users for comfort level specified in a direct load control contract, and reduced upper limit values which can be provided by all the air conditioning loads under control are calculated. A decision-making model for the direct control of the air conditioning loads in actual electric power system operation is established. Through optimization of the control strategy of all the air conditioning loads under control, the deviation between actual force exerted by the air conditioning loads and ideal reduction quantity is minimized. Moreover, continuous starting and closing time of the air conditioning loads is used for replacing constraint conditions of a real-time room temperature representation air conditioning in-turn control strategy.

Description

technical field [0001] The invention belongs to the technical field of electric power system and automation thereof. More precisely, the invention relates to a method for formulating an air-conditioning load control strategy based on direct load control. Background technique [0002] With the rapid growth of the economy and power demand, my country's power supply and demand are often in a tight state; The larger one is the air-conditioning load, which has a large number of loads and a large comprehensive capacity, and generally constitutes a peak load of electricity consumption, resulting in a further widening of the peak-to-valley difference. [0003] The power shortage is mainly manifested in the peak hours, and its duration is very short, while the power surplus in the troughs causes some generating capacity to be idle for a long time. The air-conditioning load has heat storage capacity. Centralized control of this part of the load through reasonable direct load control m...
