System Design of Internet-of-Things for Residential Smart Grid
Internet-of-Things (IoTs) envisions to integrate, coordinate, communicate,
and collaborate real-world objects in order to perform daily tasks in a more
intelligent and efficient manner. To comprehend this vision, this paper studies
the design of a large scale IoT system for smart grid application, which
constitutes a large number of home users and has the requirement of fast
response time. In particular, we focus on the messaging protocol of a universal
IoT home gateway, where our cloud enabled system consists of a backend server,
unified home gateway (UHG) at the end users, and user interface for mobile
devices. We discuss the features of such IoT system to support a large scale
deployment with a UHG and real-time residential smart grid applications. Based
on the requirements, we design an IoT system using the XMPP protocol, and
implemented in a testbed for energy management applications. To show the
effectiveness of the designed testbed, we present some results using the
proposed IoT architecture.Comment: 10 pages, 6 figures, journal pape

Privacy In The Smart Grid: An Information Flow Analysis

Power and energy visualization for the micro-management of household electricity consumption
The paper describes a pilot system for the detailed management of domestic electricity consumption aimed at minimizing demand peaks and consumer cost. Management decisions are made both interactively by consumers themselves, and where practical, automatically by computer. These decisions are based on realtime pricing and availability information, as well as current and historic usage data. The benefits of the energy strategies implied by such a system are elaborated, showing the potential for significant peak demand reduction and slowing of the need for growth in generation capacity. An overview is provided of the component technologies and interaction methods we have designed, but the paper focuses on the communication of real-time information to the consumer through a combination of specific and ambient visualizations. There is a need for both overview information (eg how much power is being used right now; how much energy have we used so far today; what does it cost?) and information at the point-of-use (is it OK to turn this dryer on now, or should I wait until later?). To assist the design of these visualizations, a survey is underway aimed at establishing people's understanding of power and energy concepts
Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities
Optimization of energy consumption in future intelligent energy networks (or
Smart Grids) will be based on grid-integrated near-real-time communications
between various grid elements in generation, transmission, distribution and
loads. This paper discusses some of the challenges and opportunities of
communications research in the areas of smart grid and smart metering. In
particular, we focus on some of the key communications challenges for realizing
interoperable and future-proof smart grid/metering networks, smart grid
security and privacy, and how some of the existing networking technologies can
be applied to energy management. Finally, we also discuss the coordinated
standardization efforts in Europe to harmonize communications standards and
protocols.Comment: To be published in IEEE Communications Surveys and Tutorial
