Operation device and method to control an air conditioner based on weather change patterns

An operation control method in which a computer, comprising a memory to store a plurality of weather change patterns as a pattern of how weather changes, and store a plurality of control plans as a plan for controlling an operation of an air conditioning equipment in accordance with the plurality of weather patterns, respectively,

• determines, at a time point midway through a time zone where the operation of the air conditioning equipment is controlled along one control plan among the plurality of control plans stored in the memory, whether a weather change pattern corresponding to the one control plan deviates from an actual weather change pattern, based on weather data indicating a time-series weather observation result of up to the time point;
• if deviates, selects a weather change pattern that is different from the weather change pattern corresponding to the one control plan, from among the plurality of weather change patterns stored in the memory, in accordance with the weather data;
• and during a rest of the time zone, controls the operation of the air conditioning equipment along a control plan corresponding to the different weather change pattern, among the plurality of control plans,
• formulates the plurality of control plans in accordance with a target value of power consumption of the air conditioning equipment in the time zone, and stores the plurality of control plans to the memory, and
• when selecting the different weather change pattern, specifies, from among the plurality of control plans, a control plan according to which a prediction value of power consumption of the air conditioning equipment during the rest of the time zone exceeds a difference between the target value and an actual value of power consumption of the air conditioning equipment of up to the time point, and excludes a weather change pattern corresponding to the specified control plan from candidates.

A non-transitory computer readable medium storing an operation control program which causes a computer, comprising a memory to store a plurality of weather change patterns as a pattern of how weather changes, and store a plurality of control plans as a plan for controlling an operation of an air conditioning equipment in accordance with the plurality of weather patterns, respectively,

• to execute a process of:
• determining, at a time point midway through a time zone where the operation of the air conditioning equipment is controlled along one control plan among the plurality of control plans stored in the memory, whether a weather change pattern corresponding to the one control plan deviates from an actual weather change pattern, based on weather data indicating a time-series weather observation result of up to the time point;
• if deviates, selecting a weather change pattern that is different from the weather change pattern corresponding to the one control plan, from among the plurality of weather change patterns stored in the memory, in accordance with the weather data;
• and during a rest of the time zone, controlling the operation of the air conditioning equipment along a control plan corresponding to the different weather change pattern, among the plurality of control plans, and
• a process of formulating the plurality of control plans in accordance with a target value of power consumption of the air conditioning equipment in the time zone, and storing the plurality of control plans to the memory,
• wherein the process of controlling the operation of the air conditioning equipment, when selecting the different weather change pattern, specifies, from among the plurality of control plans, a control plan according to which a prediction value of power consumption of the air conditioning equipment during the rest of the time zone exceeds a difference between the target value and an actual value of power consumption of the air conditioning equipment of up to the time point, and excludes a weather change pattern corresponding to the specified control plan from candidates.
