Operation management apparatus, operation management method, and operation management program

An operation management method, comprising:

• calculating an air conditioning thermal load predicted value indicating a predicted amount of heat required to adjust a temperature to a pre-set temperature on a day-of-prediction;
• calculating power generation output prediction data indicating a generated power obtained by a generator within the day-of-prediction;
• preparing an air conditioning heat source operation plan indicating allocation for every hour of operation of each of the air conditioning heat source apparatuses generating the amount of heat indicated by the air conditioning thermal load predicted value;
• calculating a predicted power load indicating the power supplied to a load device to generate the predicted amount of heat indicated by the air conditioning thermal load predicted value based on the air conditioning thermal load predicted value, and determining a purchased power corresponding to a power of the predicted power load and the generated power using the power generation output prediction data to thereby prepare a power facility operation plan indicating a schedule of a power output from the purchased power source and the generator, so that the purchased power per predetermined time supplied from a purchased power source of a commercial power system becomes a target value;
• determining whether the purchased power supplied from the purchased power source per the predetermined time exceeds the target value;
• and
• changing the air conditioning heat source operation plan and the power facility operation plan to reduce the purchased power per the predetermined time exceeding the target value when the purchased power is determined to exceed the target value by the demand excess determination unit, and increasing the purchased power per the predetermined time when the purchased power is determined not to exceed the target value,
• wherein the air conditioning heat source operation plan is changed when the purchased power is determined to exceed the target value in such a manner that an operation time period of a predetermined air conditioning heat source apparatus among the air conditioning heat source apparatuses is shifted to a time period in which the predicted power is low.

A non-transitory computer-readable storage medium comprising an operation management program causing a computer to function as:

• a unit that calculates an air conditioning thermal load predicted value indicating a predicted amount of heat required to adjust temperature to a pre-set temperature on a day-of-prediction,
• a unit that calculates power generation output prediction data indicating the generated power obtained by a generator within the day-of-prediction;
• a unit that prepares an air conditioning heat source operation plan indicating allocation for every hour of operation of each of the air conditioning heat source apparatuses generating the amount of heat indicated by the air conditioning thermal load predicted value, calculates a predicted power load indicating the power supplied to a load device to generate the predicted amount of heat indicated by the air conditioning thermal load predicted value based on the air conditioning thermal load predicted value, and determines a purchased power corresponding to a power of the predicted power load and the generated power using the power generation output prediction data to thereby prepare a power facility operation plan indicating a schedule of a power output from the purchased power source and the generator, so that the purchased power per predetermined time supplied from a purchased power source of a commercial power system becomes a target value;
• a unit that determines whether the purchased power supplied from the purchased power source per the predetermined time exceeds the target value;
• and
• a unit that changes the air conditioning heat source operation plan and the power facility operation plan to reduce the purchased power per the predetermined time exceeding the target value when the purchased power is determined to exceed the target value by the demand excess determination unit, and increases the purchased power per the predetermined time when the purchased power is determined not to exceed the target value,
• wherein the operation management program further causes a computer to function as a unit that changes the air conditioning heat source operation plan when the purchased power is determined to exceed the target value in such a manner that an operation time period of a predetermined air conditioning heat source apparatus among the air conditioning heat source apparatuses is shifted to a time period in which the predicted power load is low.
