Abstract:
1. An operation management apparatus, comprising: an air conditioning thermal load prediction unit configured to calculate an air conditioning thermal load predicted value indicating a predicted amount of heat required to adjust temperature to a pre-set temperature for a day-of-prediction; a power generation output prediction processing unit configured to calculate power generation output prediction data indicating a generated power obtained by a generator within the day-of-prediction; an operation planning unit configured to prepare 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 demand excess determination unit configured to determine whether the purchased power supplied from the purchased power source per the predetermined time exceeds the target value; and a plan change unit configured to change 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 to increase the purchased power per the predetermined time when the purchased power is determined not to exceed the target value, wherein the plan change unit is further configured to change 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.
