Transmission & Distribution of Electricity – The Challenge Peter Vaessen

CWI in bedrijf, Amsterdam, November 11th 2010

2

The digital dilemma

Data tsunami Networking/Sensors functionality

New equipment and players

Security risk ?

3

Acting on aging assets

Grey wave from the 1970-ties

Less money available Different component

life cycles Maintenance / Replacement ?

4

European Power System

495 million people served 3500 TWh/year

760 GW installed capacity 250.000 km HV network Approx. 6.000.000 km MV & LV network

Largest business sector (capital) Largest man-made system

Approximately 1500 € investment per EU citizen

5

Increased bulk transmission

DC links and interconnections

Control

50GW wind in the North?

30GW sun in the south?

Smart Equipmt.

6

Wind at sea impact

Ready for large scale deployment

AC and DC solutions Grid operation effects Sea-grid ?

7

Doing more with less

Dynamic rating needs sensors & rules

Overhead underground Public voice = CAVE Use existing right of way

8

An internet-like distribution grid

Central & local sources

Smart (power)electronics

Central & localintelligence

Integration of new applications

Real-time information & active participation

9

Solar Power up

Exponential growth Prices drop fast

from 5 to 2.5€/Wp in 2 year

Grid parity: 2015 ?

10

E-mobility (storage) a growing force

Means of decoupling generation & demand

Controllability issue Slow take off …or not ?
