PROBLEM TO BE SOLVED: To provide a charge and discharge power supply system capable of suppressing the maximum use power to a constant value or less, and to provide an integrated control method.SOLUTION: In a charge and discharge power supply system 3 including N power supply devices 30 and an integrated control section 10, the integrated control section 10 performs first processing for calculating the total power per unit time when executing a charge and discharge cycle depending on the start shift amount for the number of calculation object power supplies M (M is an integer of 1 to N), second processing for increasing the start shift amount when the maximum value of total power (expected maximum use power) exceeds a target maximum use power, and third processing for outputting a charge and discharge power instruction when the expected maximum use power is equal to or less than the target maximum use power.SELECTED DRAWING: Figure 1 |
