1 1 Smart Grid Definition and Concepts Mohsen Anvaari May 27, 2011 Software Engineering Group Department of Computer and Information Science

2 2 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

3 3 Definition What 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)

4 4 Definition What 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)

5 5 Definition What 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

6 6 Definition What 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

7 7 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.

8 8 Building Blocks Different parties have considered different structure for SG –NIST –IEEE –etc.

9 9 Building Blocks IEEE: Smart Grid 3 Fundamental Layers

10 10 Smart Grid Conceptual Architecture by Shargal and Houseman Information Technology Layer Communication Layer Power System Layer Building Blocks

11 11 Another point of view by Santacana Power Grid (Copper and Iron) Four Essential Building Blocks of Any Smart Technology Smart Grid Building Blocks

12 12 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

13 13 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?

14 14 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
