Resumen de: US20260088376A1
A charge and discharge control method for a charge and discharge element is performed every control cycle from a start time. Electric energy consumption is measured by integrating electric power consumption of a group including one or more charge and discharge elements, as a whole, from the start time to a control time at which one or more control cycles have elapsed. Target electric energy is acquired by integrating target electric power predetermined for the group as a whole from the start time to the control time. A command value is determined based on an average electric energy, which is obtained by dividing an energy difference electric obtained by subtracting the electric energy consumption from the target electric energy. The one or more charge and discharge elements autonomously control their own charge and discharge electric power based on the command value.
