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
![Page 6: Smart Grid Definition and Concepts Mohsen Anvaari May 27, 2011 Software Engineering Group](https://reader037.vdocuments.site/reader037/viewer/2022110102/568141e1550346895dadbdc5/html5/thumbnails/6.jpg)

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.

Key Issue: Interoperability• Smart Grid is a puzzle• Every attempt to implement
another piece of the Smart Gridpuzzle 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
