Claim Text:
1. A power management apparatus, comprising: a communication unit to communicate with a plurality of electrical instruments; and a controller to predict a power consumption amount of a power management area when receiving an arbitration function execution signal from at least one of the plurality of electrical instruments, compare the power consumption amount with a predetermined power amount, and adjust an operation level of at least one other electrical instrument when the power consumption amount exceeds the predetermined power amount, wherein the arbitration function execution signal corresponds to execution of at least one of a periodically performed function and a function selected by a user, wherein the operation level of the at least one other electrical instrument includes a power consumption amount consumed during operation execution at the operation level, and wherein the controller, in the adjusting of the operation level of the at least one other electrical instrument, adjusts a current operation level of the at least one other electronic instrument into an operation level having a lower power consumption amount such that an actual power consumption amount of the power management area is maintained below the predetermined power amount during the arbitration function execution.
