Smart Sensors for Demand Response

Smart Grid is being proposed as a prime solution for the effective growth of electricity market allowing the heterogeneous players to assume real-time autonomous reactions to the changing conditions of the grid and new services (such as demand response, DR, and vehicle-to-grid, V2G) to be introduced. One of the main requisite for such development is represented by advanced metering infrastructure (AMI) which typically provides timely and reliable information about the smart grid. This paper introduces an innovative first block of the AMI represented by a smart sensor based on ARM architecture. The prototype is described in terms of both the hardware and software features and the metrological characterization is provided through the experimental test according to OIML R-46.
