  • Smart Grid 101 Presentation
    The Smart Grid is a compilation of concepts, technologies, and operating practices intended to bring the electric grid into the 21 st century. Smart Grid concepts and issues are difficult to address because they include every aspect of electric generation, distribution, and use. While the scope of smart grid covers the entire utility system from generation to how customers use energy, the three chapters in this portion of the tutorial primarily focus on the intersection between the distribution grid and customer. All elements of smart grid include important engineering, economic , and policy issues. However, with the exception of alternative generation options, the generation and transmission segments are less uncertain and more dominated by engineering economics than the distribution and customer segments. This Smart Grid 101 tutorial is divided into chapters that address significant individual technical and policy areas. Each chapter attempts to isolate and define technical and policy issues relevant to state regulators. Our objective is to more clearly define the components of Smart Grid, identify how these components interact, and then present information to clarify policy and decision options. Smart Grid is often considered confusing because it covers not only the entire electric infrastructure but also new technologies, customer interaction, legal, and regulatory issues. To address this problem, each chapter addresses a limited scope of issues derived principally from meetings with regulators, industry literature, and project team professional judgment. This set of chapters address metering, rate design, and demand response. 1 Advanced meters and Smart Meters are the most visible and tangible signs of the Smart Grid. They are installed on and affect every single customer.

Wicker [email protected] [email protected] [email protected] Our first objective in writing this paper is to identify and Abstract-- There is a growing interest in ‘Smart Grid’ review certain communication technologies that we believe technologies in both industry and academic circles. Few attempts are critical for future demand response systems. Our second have been made to develop a written specification consummated objective is to provide a basis from which industry and with standards agreed upon by members of both coteries, due to lack of government support. Utilities in the state of California are academic participants can draw upon as a reference guide obligated, by state legislature, to create a more: efficient, reliable, when implementing, testing, and or simulating a demand and intelligent electric power system. This initiative along with response system. The components, we have chosen to include Florida Power & Lighting’s ‘Smart Grid’ pilot program has in the demand response system description, are by no means created a sense of exigency within the industry regarding smart standard components, however the UCAIug1 has considered grid technologies and standardizations. Their accomplishments these components to be an integral part of any demand are beginning to shape the policies and standards with marginal input from academic societies, ushering in a very lopsided, and response system. Even though we will reference material, business acclimatized set of standards. We will present and which has yet to be approved by an official standards body analyze, a SCE ‘Smart Grid’ use case, in which the utilities back such as IEEE, we feel confident that most utilities, many of office applications interact with the customer’s meter, and which have contributed to the development of this material, provide technical recommendations for system security will adopt a similar AMI system design if they haven’t improvements.

ZigBee enables a customer to connect intelligent displays (called In-Home Displays, or IHD) wirelessly to the smart meter to receive real-time energy consumption data. ZigBee gives customers ways to save energy by connecting a washing machine or a fridge to the utility's current electricity price feed and adjust their time of use automatically. Although currently all smart meters have the wireless interface disabled, the utilities are starting to enable it for pilot users. However, this new wireless functionality comes with security risks. This project is about the analysis of security and privacy issues of ZigBee implementations.

  • Home Area Network: Architectural Considerations for Rapid Innovation
    Home Area Network: Architectural Considerations for Rapid Innovation WHITE PAPER Trilliant helps leading utilities and energy retailers achieve their smart grid visions through the Trilliant Communications Platform, the only communications platform purpose-built for the energy industry that integrates disparate systems of systems into a unified whole. The Trilliant Platform is deployed with more than 200 utilities worldwide to enhance energy efficiency, improve grid reliability, lower operating costs, integrate renewable energy resources and electric vehicles, and empower consumers to better manage their energy consumption. 1100 Island Drive Redwood City, CA 94065 t 650-204-5050 f 650-508-8096 www.trilliantinc.com Introduction Two recent reports published by ON World, a research firm providing business intelligence on smart technology markets, predict that 100 million smart meters will be deployed in the next five years and that half of these will have a built‐in Home‐Area Network (HAN) gateway for in‐home energy management programs and services. ON World’s survey of 77 utilities in the United States also found that 21% are planning to integrate a HAN gateway into every smart meter deployed.1 The question addressed in this white paper is whether or not this integration of the HAN gateway function into the smart meter is a smart architecture for the Smart Grid? Before examining the architectural alternatives for the HAN gateway, some background information is provided in the next two sections on The HAN’s Value in the Smart Grid and HAN Architectures in Existing Standards. The two viable HAN gateway architectures (integration into the smart meter and the dedicated in‐home gateway device) are then evaluated in detail using four criteria.
