The invention relates to an air conditioner load priority interruption method based on the electricity utilization comfort level. The air conditioner load priority interruption method comprises the following steps that (1) an air conditioner response time interval and control time interval length are determined, air conditioner load peak clipping total amount in the response time interval is determined, and on-off states of all air conditioners and indoor temperature data in a control time interval are collected; (2) temperature set values and floating ranges of all the air conditioners are determined; (3) electricity utilization comfort level indexes of air conditioner load and corresponding air conditioner load control models are established; (4) the air conditioner electricity utilization comfort level indexes and corresponding air conditioner load states are worked out according to the actual data; and (5) all the comfort level indexes are ranked by magnitude, and a final air conditioner interruption scheme is determined with combination of the air conditioner load peak clipping total amount. The air conditioner load priority interruption method based on calculation of the electricity utilization comfort level indexes has feasibility and effectiveness; concrete reference schemes are provided for air conditioner load participating peak clipping during application; the optimization effect of the electricity utilization comfort level is ensured to the greatest extent while the requirement for power grid peak clipping is met.
