Developments of the In-Home Display Systems for Residential Energy Monitoring

Abstract:

               The residential sector, unlike the commercial or industrial sector, is composed of multiple small energy consumers and wastes significant amount of supplied electric power. This fact implies the potential of the energy saving in the residential side. In order to efficiently reduce the amount of electricity waste in the residential side, the consumer needs to change the usage behavior. Research in real-time energy monitoring has been conducted recently. From the monitoring, the energy consumption patterns are acquired and can be analyzed for the reduction of the energy consumption. In order to efficiently reduce the amount of the electricity usage in the residential area, the demand response (DR) of the consumers is of importance. The in-home display (IHD) system provides energy monitoring information for the consumer DR. Recently; we have developed several types of IHD systems, which are based on 2.4GHz ZigBee, the power line communication technique, and the sub-GHz narrow-bandwidth radios. In this paper, different types of IHDs are introduced and their technologies including network architectures are compared
