METHOD AND SYSTEM FOR MANAGING ELECTRIC POWER
First Claim
1. A method of managing power devices, the method comprising:
- operating a first power generator according to a predetermined operating plan;
determining an amount of available stored power by subtracting a required amount of emergency power from a total amount of power stored in an energy storage system (ESS) when an amount of generated power of the first power generator is less than an amount of power required by a plurality of power use devices;
operating a second power generator when a first sum of an amount of generated power of the first power generator and the determined amount of available stored power is less than the required amount of power; and
interrupting power provided to the at least one of the plurality of power use devices in ascending order of priority when a second sum of the amount of generated power of the first power generator and an amount of generated power of the second power generator is less than the required amount of power.

Abstract
An electric power management method of an electric power management device includes controlling a first power generator to operate according to a preset operating plan, calculating an available amount of stored power by subtracting a required amount of emergency power from an amount of electric power stored in an energy storage system when a power generation amount of the first power generator is less than an electric power use amount of a plurality of electric power use devices, controlling a second power to operate when a sum of the power generation amount of the first power generator and the amount of electrical power stored in the energy management system is less than the electric power use amount, and interrupting electric power of the electric power use devices in ascending order of priority.

11. A power management system comprising:
-
a plurality of power generators configured to generate power; an energy storage system (ESS) configured to store power; a plurality of power use devices configured to use power; an ESS control unit configured to determine an amount of available stored power by subtracting a required amount of emergency power from a total amount of power stored in the ESS; a power generator operation control unit configured to; operate a first power generator according to a predetermined operating plan; determine that an amount of generated power of the first power generator is less than an amount of power required by a plurality of power use devices; and operate a second power generator when a first sum of an amount of generated power of the first power generator and the determined amount of available stored power is less than the required amount of power; and an electric power interruption control unit configured to interrupt power provided to at least one of the plurality of power use devices in ascending order of priority when a second sum of the amount of generated power of the first power generator and amount of generated power of the second power generator is less than the required amount of power use. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
