PURPOSE: A power control method for secondary batteries is provided to control input-output electricity according to the state of each secondary battery and to compensate output change of natural energy generator, thereby uniformizing generated output of an integrated system. CONSTITUTION: A connection system(8) supplies power to an electric power system by combining a generator in which the output power changes and electric power storage compensators(5). Plural secondary batteries compensate the change of output power of the generator through a power storage compensator. A method for controlling electric power of a secondary battery comprises the steps of: dividing plural secondary batteries into an electrostatic force control group and a frequently responding group; and distributing preset input-output electricity to the electrostatic force control group and then distributing the residual input-output electricity to the frequently responding group. |
