The customer domain of the smart grid naturally
blends with smart home and smart building systems, but typical proposed
approaches are “distributor-centric” rather than “customer-centric,”
undermining user acceptance, and are often poorly scalable. To solve this
problem, we propose a detailed architecture and an implementation of a
“last-meter” smart grid—the portion of the smart grid on customer premises—embedded
in an internet-of-things (IoT) platform. Our approach has four aspects of
novelty and advantages with respect to the state of the art: 1) seamless
integration of smart grid with smart home applications in the same
infrastructure; 2) data gathering from heterogeneous sensor communication
protocols; 3) secure and customized data access; and 4) univocal sensor and
actuator mapping to a common abstraction layer on which additional concurrent
applications can be built. A demonstrator has been built and tested with
purposely-developed ZigBee smart meters and gateways, a distributed IoT server,
and a flexible user interface.
