20140142724 | APPARATUS AND METHOD FOR NON-INTRUSIVE LOAD MONITORING (NILM) - An apparatus and method for non-intrusive load monitoring (NILM). The NILM apparatus is aimed at updating reference data of a storage unit established by a generalized method to increase reliability of the storage unit. The NILM apparatus includes: a sensor unit configured to collect information about power consumed by an appliance; a controller configured to acquire a power consumption pattern of the appliance based on the collected power information, and to identify the appliance using the power consumption pattern; a display unit configured to display the result of the identification so as for a user to determine whether the result of the identification using the power consumption pattern is correct; and storage unit configured to store the result of the identification if it is determined that the result of the identification displayed on the display unit is correct. | 05-22-2014 |
20150134140 | ELECTRIC DEVICE, POWER MANAGEMENT SYSTEM INCLUDING THE ELECTRIC DEVICE, AND METHOD FOR CONTROLLING THE SAME - A power management apparatus includes an electric device including a plurality of operation algorithm information and power information for each operation level corresponding to each operation algorithm information, and a power management unit to receive power rate information from a power provider, determine an operation level of the electric device on the basis of the received power rate information and power information for each operation level of the electric device, and control an operation of the electric device at the determined operation level. As a result, the power management apparatus performs different operation algorithms according to power rate information, and controls power consumption of the electric device, such that energy efficiency at the user side can be maximized. In response to the changed power rate information, the currently-driven electric device and the electric device to be driven can be driven at the optimum operation level appropriate for their power consumption characteristics. | 05-14-2015 |
