Developments of the in-home display systems for residential energy monitoring

Abstract

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.
