  1. 1. • Background and Goals• What a Smart Grid is• Modernizes both Transmission&Distribution• Problem Definition• Smart Grid Functions• Features• Technology• Recent Studies• Obstacles• Conclusion• References• External Links
  2. 2. • 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]
  3. 3. • 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]
  4. 4. • Smart energy demand describes the energy user component of smart grid.• Smart energy demand is a broad concept: • Enhancement of reliability • Reduce peak demand • Shift usage to off-peak hours • Lower total energy consumption • Actively manage electric vehicle charging • Actively manage other usage to respond solar, wind, and other renewable resources
  5. 5. • Smart energy demand mechanisms and tactics include: • Smart meters • Dynamic pricing • Smart thermostats and smart appliances • Automated control of equipment • Usage by appliance data • Scheduling and control of loads• Scale and Scope[6]• Municipal grid[7]• Home Area Networks (HANs) • Zigbee, INSTEON, Zwave,WiFi or others.
  6. 6. • 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
  7. 7. • 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
  8. 8. • 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]
  9. 9. • 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
  10. 10. • 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
  11. 11. • 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
  12. 12. • Integrated communications • Substation automation • Demand response • Distribution response • Distribution automation • Supervisory control and data acquisition(SCADA) • Energy management systems • Wireless mesh networks • Power-line carrier communications• Smart meters • Digital meters that record usage in real-time
  13. 13. • Phasor measurement units (PMU) • Distributed throughput their network can be used to monitor power quality and in some cases respond autmatically to them.• Sensing and measurement • Evaluate congestion and grid stability,monitoring equipment health, energy theft prevention, and control strategies support. • Technologies: wide-area monitoring systems, dynamic line rating, electromagnetic signature measurement/analysis, real-time pricing tools, backscatter radio technology
  14. 14. • Advanced control • Distributed intelligent agents • Analytical tools • Operational tools (SCADA, substation automation, demand response, etc.)• Improved interfaces and decision support • Operators and managers have tools to effectively and efficiently operate a grid with an increasing number of variables.• Smart power generation • A concept of matching electricity production with demand using multiple identical generators. [12]
  15. 15. • Using artificial intelligence programming techniques, Fujian power grid in China. [13]• The power grid was considered within the context of: • Optimal control • Ecology • Human cognition • Glassy dynamics • Information theory • Microphysics of clouds and many others. [14]• Many different concepts have been used to model intelligent power grids.
  16. 16. • In Europe and the U.S, significant impediments exist to the widespread adoption of Smart Grid technologies; • Regulatory environments that not reward utilities for operational efficiency,excluding U.S. Awards • Consumer concerns over privacy • Social concerns over «fair» availability of electricity • Social concerns over Enron style abuses of information leverage • Limited ability of utilities to rapidly transform their business and operational environment
  17. 17. • Distinguishing characteristics of Smart Grid include[15]: • Increased use of digital information and controls technology to improve reliability, security, and efficiency of the electric grid • Dynamic optimization of grid operations and resources with cyber-security • Deployment and integration of distributed resources and generation, including renewable resources • Deployment and incorporation of demand response, demand-side resources, and energy-efficiency resources
  18. 18. • Deployment of «smart» technologies for metering, communications concerning grid operations and status, and distribution automation• Integration of «smart» appliances and consumer devices• Deployment and integration of advanced electricity storage and peak-shaving technologies• Provision to consumers of timely information and control options• Development of standards for communication and interoperability of appliances and equipment connected to the electric grid
