Smart Grids
- why and what - From traditional to smart grids
traditional grid • Centralized power generation
• One-directional power flow
• Generation follows load
• Top-down operations planning

• Operation based on historical
experience

• Centralized and distributed power
smart grids

• Multi-directional power flow
• Consumption integrated in system
operation
• Operation based on real-time data

• Goal: Automatic isolation and location of faults,
very fast service restoration to customers
• How: Using information from IEDs, sensors and meters to control
switchgear and to pinpoint fault location
• Financial drivers

– Improved customer satisfaction
– Avoided penalties
– Reduction of operational expenses (e.g. crew costs, tree trimming)
• Solution areas
– Improved coordination and integration
– Utilization of advanced metering infrastructure
– Outage support


Smart Grids
drivers
Renewable and Distributed
Generation
• Goal: Ensuring reliable grid operation in systems
with high share of generation based on volatile
renewable energy (e.g. wind and solar) and

maybe economic storage

• How (examples):
– Wind and PV specific protection and control systems
supporting
– Wind and PV specific substations and power electronics
Smart Grids
– HVDC to connect remote wind and solar thermal plants

• Financial drivers
– Emission reduction
– Maintaining security of supply despite volatile generation
• Solution areas
– Improved coordination and integration
• integrated communication infrastructure
• distributed generation, energy storage and demand response
– Outage support
• restoration switching alternatives
• peak load shifting to defer generation investments

The need for more Transmission investment
Development of a Pan-European transmission grid requires investments!

Drivers
•Rising electricity demand

•Integration and accommodation of
renewable energies
•More cross-border energy trade
•High regional electricity prices
•Energy security concerns
•Stability Improvement

The ENTSO-e countries need to
invest 22 to 24 Bil. EUR on
their Transmission Network
between 2010 -2014
