Abstract
Provided is a power management system capable of controlling charge and discharge of storage batteries according to power requirement of load even when handling electric power of large scale. A system controller receives load-related information data including the power requirement of load and storage battery-related information data including a state of a storage battery assembly including multiple storage batteries and creates an overall charge-discharge control instruction for the entire power management system based on the load-related information data and the storage battery-related information data. A hierarchical charge-discharge control apparatus receives the overall charge-discharge control instruction from the system controller and performs charge-discharge control of the multiple storage batteries, classified into hierarchical levels, on a hierarchical level basis.
