Charging/discharging system for solar light power generator in smart grid environment with real-time pricing, duplex convertor of charging/discharging system, and charging/discharging method for solar light power generator
First Claim
1. A charging and discharging system for a solar light power generator in a smart grid environment with real-time pricing, the charging and discharging system comprising:
- an electricity price monitoring part which collects electricity price information from an electric grid;
an electricity charge amount monitoring part which collects electricity charge amount information of a battery of the charging and discharging system;
a charge and discharge determination part which determines, based on the collected electricity price information and the collected electricity charge amount information, whether electricity supplied from the electric grid is to be charged into the battery or whether electricity stored in the battery via at least one of the electric grid and the solar light power generator is to be discharged to the electric grid; and
a charging and discharging part which selectively performs one of charging the battery and discharging the battery based on the determination made by the charge and discharge determination part; and
a metering part which measures electricity usage based on an amount of electricity charged into the battery and an amount of electricity discharged from the battery and which calculates an electricity price based on the measured electricity usage.

Abstract
Provided are a charging and discharging system for a solar light power generator in a smart grid environment, a method of operating the same, and a duplex converter for charging and discharging electricity into/from a battery. The system includes: an electricity price monitoring part which collects electricity price information from an electric grid; an electricity charge amount monitoring part which collects electricity charge amount information of a battery; a charge and discharge determination part which determines whether electricity supplied from the electric grid is to be charged into the battery or whether electricity stored in the battery via the electric grid or the solar light power generator is to be discharged to the electric grid, based on the price information and the charge amount information; and a charging and discharging part including the battery, so that electricity is charged into or discharged from the battery based on the determination.

8. A method of charging and discharging electricity into/from a battery of a charging and discharging part of a charging and discharging system for a solar light power generator in a smart grid environment with real-time pricing, the method comprising:
-
receiving electricity price information from an electric grid; receiving electricity charge amount information of the battery; determining whether electricity is to be purchased from the electric grid or whether electricity stored in the battery via at least one of the electric grid and the solar light power generator is to be sold to the electric grid, based on the received electricity price information and the received electricity charge amount information; and
;selectively performing one of charging and discharging the battery, based on a result of the determining; and measuring electricity usage based on an amount of electricity charged into the battery and an amount of electricity discharged from the battery and calculating an electricity price based on the measured electricity usage. - View Dependent Claims (9, 10)
