1. An energy supply plan formulation device for formulating an energy supply plan to be used for controlling an operation of at least one energy equipment which inputs and/or outputs energy from/to an energy supply target, on the basis of an equipment model corresponding to the energy equipment and a load model corresponding to the energy supply target,
wherein the equipment model is data indicating energy input/output characteristics of the corresponding energy equipment, and
the load model is a physical formula or an arithmetic operation method used for forecasting the amount of energy demand of the corresponding energy supply target,
the energy supply plan formulation device comprising:
at least one processor to execute a program and
at least one memory to store the program which, when it is executed by the processor, causes the processor to be configured to:
acquire a change of a base load of the energy equipment through analysis of time-series operational data of the at least one energy equipment to detect a deviation in energy input/output characteristics;
determine whether to need correction of at least one of the equipment model and the load model on the basis of the change of the base load to maintain accuracy of the energy supply plan in response to the detected deviation;
correct at least one of the equipment model and the load model on the basis of a determination result to adjust the energy input/output characteristics or the physical formula based on the detected deviation;
forecast the amount of energy demand of the energy supply target using the corrected at least one of the equipment model and the load model; and
formulate an energy supply plan on the basis of the equipment model and the amount of energy demand; and
output the energy supply plan to control the operation of the at least one energy equipment to supply energy to the supply target; and
control the operation of the at least one energy equipment to supply energy to the energy supply target based on the energy supply plan.
