Research on electricity consumption of air conditioners based on big data

In order to realize the flexible load control of air conditioners and other electrical equipment during the peak period of electricity consumption in summer,and to avoid extreme power regulation and control phenomena such as power grid shutdown and power rationing,this paper establishes a simplified calculation model of electricity consumption and an energy consumption model for air conditioners.Combined with the actual operation data of 200 000 air conditioners,the user’s temperature setting habits and the change law of energy consumption with the set temperature are studied,and the suggestions for flexible regulation of air conditioner electricity consumption are put forward.The results show that the simplified calculation model of electricity consumption is effective after actual engineering verification,and the error can be controlled within 5%.Every 1 ℃ increase in the cooling set temperature can save 0.054 kW·h of the electricity,and every 1 ℃ decrease in the heating process can save 0.061 kW·h of the electricity.Flexible regulation of electricity consumption can be realized through direct power limitation or indirect temperature limitation.
