A wireless power transmission system, and an apparatus and method for controlling power in the wireless power transmission system are provided. The method includes determining a resonance frequency of the wireless power transmission system in which a wireless power transmission efficiency is greater than or equal to a predetermined value. The method further includes generating an operation power based on the wireless power transmission efficiency, the operation power being used to operate a target device. The method further includes transmitting the operation power to the target device. The method further includes controlling an amount of the operation power received by the target device to be within a predetermined range.
