Smart Grid Definition and Concepts Mohsen Anvaari May 27, 2011 Software Engineering Group Department of Computer and Information Science
Agenda • Definition: What It Is and What It Is Not? • Characteristics, Goals and Benefits • Building Blocks: What It Is Made Of? • Key Issue: Interoperability • Our Task: SEinSG (Software Evolution in Smart Grid) • Questions
DefinitionWhat It Is? • There is yet no internationally unified definition and nobody exactly know what it is • Even not unified term: Smart Grid, SmartGrids, Smarter Grid, Intelligent Grid, Future Grid, Modern Grid • However, the most commonly used term is “Smart Grid” • Many parties have published definitions • Some focusing on the technologies might be deployed in SG • Others on the services SG can offer • Some well-known definitions are from: • US Department of Energy (DOE), European Technology Platform on Smart Systems Integration (EPoSS), International Electrotechnical Commission (IEC), Electric Power Research Institute (EPRI)
DefinitionWhat It Is? • EPoSS definition: Smart Grid is an electricity network that can intelligently integrate the actions of all users connected to it – generators, consumers, and those that do both, in order to efficiently deliver sustainable, economic and secure electricity supply (Technology Action Plan: Smart Grids, Report to the Major Economies Forum on Energy and Climate, Prepared by Italy and Korea in consultation with MEF Partners, December 2009) • DOE definition: An automated, widely distributed energy delivery network, the Smart Grid will be characterized by a two-way flow of electricity and information and will be capable of monitoring everything from power plants to customer preferences to individual appliances. (The Smart Grid: An Introduction, a publication sponsored by the US Department Of Energy’s (DOE) Office of Electricity Delivery and Energy Reliability)
DefinitionWhat It Is? • Precise definition or easy to understand? • A simple description (by Jesse Berst): • Smart devices • Two-way communications • Advanced control systems • Smart Grid = Present-day Electricity Grid (copper and iron) + Intelligence
DefinitionWhat It Is Not? • Smart Grid relates to the electricity network only (not gas) • Smart Grid will not look significantly different from today’s conventional electricity grids (copper and iron cables) • Smart Grid will not be a revolution but rather an evolution • Smart metering alone is not Smart Grid • smart metering enables some features and functionalities of smart grid
Characteristics, Goals and Benefits • Self-healing: the capability to rapidly detect, analyze, respond and restore from the fault • Consumer friendly: the ability to involve a consumer into a grid • High reliability: a quality of the power must satisfy consumer needs • Resilient: immunity to cyber and physical attacks • Distributed generation and storage options: adapt to new technologies such as solar cells and electric vehicles • Renewable energy integration: integrating more ecological and non-polluting power generation such as wind turbines • Optimizes asset utilization: monitoring and optimization of its capital assets and minimizes operations and maintenance expenses.
Building Blocks • Different parties have considered different structure for SG • NIST • IEEE • etc.
Building Blocks IEEE: Smart Grid 3 Fundamental Layers
Building Blocks • Smart Grid Conceptual Architecture by Shargal and Houseman Information Technology Layer Communication Layer Power System Layer
Building Blocks • Another point of view by Santacana Four Essential Building Blocks of Any Smart Technology Smart Grid Power Grid (Copper and Iron)
Key Issue: Interoperability • Smart Grid is a puzzle • Every attempt to implement another piece of the Smart Grid puzzle is plagued by difficulty • Possible approaches to this problem: • One Stop, One Shop • Vender to Vender Cooperation • Industry Standards • System Integrators • Service Oriented Architecture • Brute Force • A combination of these approaches
Our Task: Software Evolution in Smart Grid • Smartness in Smart Grid assumes many software-driven services and equipment • Such software is in a never-ending state of flux because of changing expectations from the direct and indirect users of software-driven artifacts • The actual software is developed and run by a large number of companies in many countries Question: When, how and by whom should then a piece of software be evolved?
Our Task: Software Evolution in Smart Grid • Improved Management of Software Evolution for Smart Grid applications: • A: Open Source Software in SmartGrids: Investigating the well-suitedness of Open Source Software (OSS) in the Smart Grid context • B: Evaluation of Software Application Portfolios: Looking at methods for proposing and assessing evolution alternatives for a portfolio of software applications
