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
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.
