The document discusses the future power system and the challenges and opportunities it presents. It makes three key points: 1) The future energy system will be based on electricity generated from a variety of renewable and alternative energy sources to help address environmental problems. This will require a stronger transmission grid. 2) As more renewable energy is added, transmission system operators will need new operational tools to ensure a secure supply of electricity to all customers. This includes building transmission lines and using energy markets. 3) Significant investments totaling at least 50 billion Norwegian krone will be needed by 2030 to build a robust transmission grid in Norway that can accommodate more renewable energy on the system and allow for tighter cooperation between Nordic transmission system

2. Visions Of The Future
 The key issue in solving our environmental
problems is to change our energy sources
 Fortunately, an array of alternative energy
technologies are coming on-line that will make
possible abundant, cheap, and clean energy.
 The future energy will be based
on electricity

3. The role of the TSO (transmission system operator)
 "Secure supply at any time to everybody"
 Tools:
1. Operational tools – SCADA/EMS
2. Using and developing the energy markets
3. Building overhead lines

4. Our common challenge: Less CO2, more electricity
 More renewables
 Stronger grid
CO2-emission/cap

8. 2011 2030
 Important regional reinforcements
 A 420 kV main grid
 Strong presence in North of Norway
 Tight cooperation among Nordic TSO’s
 More cross border connections
At least 50 billion NOK to
be invested within 2030
Towards 2030
Build a robust and environmental friendly Main Grid

9. In addition Smart Grid Operation
Ensure a safe and efficient operation
 Background
 We have experienced some years with strained energy situations, more N-0
operation, reduced frequency quality and voltage regulation problems
 But less faults for end customers

It is about exploiting the renewable resources….
- How to transfer the power

12. Smart Grid is not enough – Need Smart Operation
 Centralized power generation
 One-directional power flow
 Operation based on historical
experience
 Centralized and distributed power
generation (renewable)
 Multi-directional power flow
 Operation based on real time data
Traditional grid & Operation Smart Grid & Operation

13. Flexibility is crucial …
- To have access to flexibility is a need in the future power system
• Design and long term
planning
• Operational Planning
• On-line operation
WAMS, WACS, WAPS are enabling systems for Smart grid and key
building block are PMUs, FDR and RTU

 Many of the challenges
can also be solved locally
by grid users
 In order to find the most
cost-effective solutions, a
wide cooperation
between TSOs, DSOs,
regulators and grid users
is needed
Smart SuperGrids do not
help if we have
StupidProduction and
StupidDemand!
TSO cooperation is not enough
