POWER MANAGEMENT SYSTEM
First Claim
1. A power management system comprising:
- a system controller configured to receive load-related information data including the power requirement of a load and storage battery-related information data including the state of a storage battery assembly including a plurality of storage batteries and to create 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; and
a hierarchical charge-discharge control apparatus configured to receive the overall charge-discharge control instruction from the system controller and to perform charge-discharge control of the plurality of storage batteries, which are classified into a plurality of hierarchical levels, on a hierarchical level basis.

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.
