Background
• Current power grid evolved after 1896 based on Nikola Tesla’s design
• Electric grid of the late 1960’s became conceived of as « dividing and distributing» electric power
• Electricity networks have not kept pace with modern challenges
• The term smart grid has been in use since at least 2005.[1]
![Page 6: Smartgrid evrim guler](https://reader036.vdocuments.us/reader036/viewer/2022062319/554a8454b4c90579288b5739/html5/thumbnails/6.jpg)
Background
• First cities with smart grids:• The earliest and still largest, Italian system installed by
Enel S.p.A( Ente Nazionale per l’Energia eLettrica) of Italy.• In the US, the city of Austin,TX has been working on
building its smart grid since 2003.[2]• Hydro One, in Ontario,Canada is in the midst of a large-
scale Smart grid initiative.[3][4]• The city of Mannheim in Germany is using real-time
Broadband Powerline(BPL) communications.[5]

What a Smart Grid is
• Smart Grid refers using computer-based remote control and automation.
• Smart grids increase• The connectivity• Automation • Coordination
between these suppliers, consumers and networks that perform either long distance transmission or local distribution tasks
![Page 10: Smartgrid evrim guler](https://reader036.vdocuments.us/reader036/viewer/2022062319/554a8454b4c90579288b5739/html5/thumbnails/10.jpg)
What a Smart Grid is
![Page 11: Smartgrid evrim guler](https://reader036.vdocuments.us/reader036/viewer/2022062319/554a8454b4c90579288b5739/html5/thumbnails/11.jpg)
Modernizes both Transmission and Distribution
• Many smart grid features apparent to consumers• Peak curtailment/leveling and time of use pricing• To reduce demand during the high cost peak usage periods• To reduce consumption by communication to devices directly
in order to prevent system overloads• Platform for advanced services• Use of robust two-way communications,advanced sensors,
and distributed computing technology• US and UK savings estimates and concerns [8][9]• Save consumers money • Help reduce CO₂ emissions
![Page 12: Smartgrid evrim guler](https://reader036.vdocuments.us/reader036/viewer/2022062319/554a8454b4c90579288b5739/html5/thumbnails/12.jpg)
Problem Definition
• Increasing reliability,efficiency and safety of power grid
• Enabling decentralized power generation
• Flexibility of power consumption at the clients side
• Increase Gross Domestic Product (GDP) by creating more new, green-collar energy jobs [10][11]
![Page 13: Smartgrid evrim guler](https://reader036.vdocuments.us/reader036/viewer/2022062319/554a8454b4c90579288b5739/html5/thumbnails/13.jpg)
Smart Grid Functions
• A modern Smart Grid must [11]:• Be able to heal itself• Motivate consumers to actively participate in operations
of the grid• Resist attack• Provide higher quality power• Accommodate all generation and storage options• Enable electricity markets to flourish• Run more efficiently• Enable higher penetration of intermittent power
generation sources
![Page 14: Smartgrid evrim guler](https://reader036.vdocuments.us/reader036/viewer/2022062319/554a8454b4c90579288b5739/html5/thumbnails/14.jpg)
Features
• Load Adjustment• The total load connected to the power grid can vary
significantly over time.
• Demand response support• Allows generators and loads to interact in an automated
fashion in real-time, coordinating demand to flatten spikes.
• Greater resillience to loading• Initial power lines in the grid were built using radial model,
later connectivity was guaranteed via multiple routes
![Page 15: Smartgrid evrim guler](https://reader036.vdocuments.us/reader036/viewer/2022062319/554a8454b4c90579288b5739/html5/thumbnails/15.jpg)
Features
• Decentralization of power generation• If a local sub-network generates more power than it is
consuming, the reverse flow can raise safety and reliability issues.
• Price signaling to consumers• In many countries, the electric utilities have installed
double tariff electricity meters in many homes
