Abstract

Provided is a network system that includes an advanced metering infrastructure and an energy management system. The advanced metering infrastructure communicates with a power supply source and measures energy supplied from the power supply source. The energy management system is connected to the advanced metering infrastructure to communicate with it and controls an operation of an electric product based on information about the operation of the electric product or energy information supplied from the power supply source. A normal mode operated based on setting by a user, and a saving mode for saving power consumption or an electricity charge based on the energy information are defined in the electric product or the energy management system. The using of an electric product in a time period where an electricity charge per time is a predetermined reference or greater is suppressed, or the operation thereof is delayed to save an electricity charge.
