Implementing Smart Grids Driving Factors  Competition  Security and quality of supply  Global targets on environmental protection

Implementing Smart Grids Enabling Technologies  most important basis for a comprehensive implementation: Information and communication technologies  Sensing and measurement technologies  Advanced components  Advanced control methods  Improved interfaces and decision support

Case Study: Great Walser Valley 1. Reserves are available (Source: BMVIT 2010)

Case Study: Great Walser Valley 2. No measures will cause undue transgression of the maximal eletrical potential (Source: BMVIT 2010)

Case Study: Great Walser Valley 3. Solution with a permantent demand management (Source: BMVIT 2010)

Future of Smart grids  HDVC Powerlines  Smart meters  Smart Grid 2.0

Visions  US-Strategies (Source: DOE 2010)
