Abstract: A system and method for automatically controlling an energy apparatus using an energy modeling technique is disclosed. The energy management service system for managing the use of energy of each region may include an energy collecting unit to collect energy usage information of an energy apparatus consuming energy in a region through a remote metering server, an apparatus collecting unit to collect control state information of the energy apparatus through a home network device installed in the region to control the operation of the energy apparatus, and an energy management unit to determine an energy usage control factor based on the energy usage trend and to automatically control the operation of the energy apparatus based on the energy usage control factor.

Abstract: In a smart energy management system linked with home network devices respectively installed in a plurality of households to manage the use of energy for each household, a location detecting unit detects location information or entry/exit information of a household member through recognition of an RFID tag carried by the household member connected with an RFID receiving device. An energy recording unit receives energy use details of the household, inputted from the home network device, and records the received energy use details together with the location information or entry/exit information of the household member. A pattern analysis unit analyzes an energy use pattern for the energy use details. An energy management unit provides the energy use details through the home network device as a result obtained by comparing the energy use detailed for each household or so that the household member recognizes the energy use pattern.
