Smart Grid Technologies
Examples and Impacts on PQ
- Other names: Intelligent grid, Modern grid
and Future grid
- Various definitions 
USA: self-healing, active participation by consumers, operate resiliently, provide quality power, accommodate all generation and storage options, optimize asset utilization and operate efficiency.
The Department of Energy’s (DOE) Smart Grid Task Force defines 7 characteristics of smart grid:
1. Enable active participation by consumers
2. Accommodate all generation and storage options
3. Enable new products, services, and markets
4. Provide power quality for the range of needs in a digital economy
5. Optimize asset utilization and operating efficiency
6. Anticipate and respond to system disturbances in a self-healing
7. Operate resiliently against physical and cyber attacks, and natural
Europe (European Commission report): flexible, accessible, reliable an economical.
China: An electricity transmission and distribution system that incorporates elements of traditional and cutting-edge power engineering, sophisticated sensing and monitoring technology, information technology, and communications to provide better grid performance and to support a wide range of additional services to consumers.
SG challenges: Deliver both energy and information 
Nerves that transmit
perception and motor signals
Body’s sensory and
are required for this layer.
(e.g. superconducting cables)
1) Harmonics and Interharmonics
2) Voltage dips (sags) and Interruptions
3) Voltage fluctuation and Flicker
4) Voltage transients
5) Voltage unbalance (imbalance)
6) Power-frequency variation
existing and emerging standards-based, interoperable technologies working together.
