Abstract

Disclosed are an energy management system, an energy management method and a repeater for an energy management system. The repeater receives information on an amount of energy consumption of the individual user from the meter, and receives information on an energy pricing system from the central management server. Then, the repeater analyzes and manages the energy consumption rate of the individual user using the received information, and transmits information on the energy consumption rate to the meter or the central management server. The repeater may also analyze various information such as information on an energy consumption propensity of the individual user. The repeater immediately transmits essential information but transmits incidental information only when there is a request of the meter or the central management server. Accordingly, it is possible to reduce communication traffic between the central management server and the plurality of meters.

Claims

1. An energy management system, comprising:

a meter configured to inspect an amount of energy consumption and transmit information on the amount of energy consumption to a repeater through a first communication network;

a central management server configured to transmit information on an energy pricing system to the repeater through a second communication network, and receive information an energy consumption rate of an individual user from the repeater; and

a repeater configured to store the information on the amount of energy consumption, received from the meter, and the information on the energy pricing system, received from the central management server, and calculate the energy consumption rate of the individual user and then transmit the calculated energy consumption rate to the central management sever.

2. The energy management system of claim 1, wherein the first and second communication networks use the same type of network.

3. The energy management system of claim 1, wherein the first communication network is a local area network (LAN), and the second communication network is a wide area network (WAN).

4. The energy management system of claim 1, wherein the first communication network comprises at least one of a wireless LAN (WLAN), a power line communication (PLC) network, a Bluetooth network and a Zigbee network.

5.
