1 IEEE PES Conference Innovative Smart Grids Technologies PLenary Session 1, 11 October 2010 On Smart Electric Power Systems Sture Larsson Technical Director, deputy CEO Svenska Kraftnät The Swedish Transmission System Operator

2 Smart Grids Development of the existing power system by integration of modern transmission and information technology

3 Smart Grids Development of the existing power system by integration of modern transmission and information technology Smart Grids Smart Systems: > The Grids > What is connected to the Grids - Generation - Consumption

4 Smart Grids Development of the existing power system by integration of modern transmission and information technology > Why? What are the driving forces? > Who shall pay? > What is the smartest way to do it?

5 Smart Grids Development of the existing power system by integration of modern transmission and information technology > Why? What are the driving forces? > Who shall pay? > What is the smartest way to do it? - Technically - Economically

6 Investments to meet the climatic challenges dollar Investments in Electrical Energy up to /3 to 1/2 of the investments needed in transmission source: World Energy Outlook, 2006 (+ exchange rates corrections to 08)

7 A 20XX large-net European vision - based on smart thinking Hydro power Solar power Wind power DC transmission Hydro 200 GW Wind 300 GW Solar 700 GW 7

8 Svenska Kraftnät s Smart Grid vision Objective of the Nordic TSOs To develop the Nordic Power system to support the climate and energy policies laid out to reach the EU Commission sustainability targets 20/20/20 at year and beyond that!

9 Wind Power Development Scenarios in Sweden National planning target set to facilitate: 30 TWh / MW Summary of all identified projects: > MW / 90 TWh Presently installed capacity: Hydro MW Nuclear MW

10 Identified projects in northern Norway Nordkyn 750 MW Eliastoppen 40 MW Skjøtningberg 400 MW Laukvikdalsfjellet 70 MW Havøygavlen 40 MW Gartefjell 40 MW Seglkollfjellet 350 MW Snefjord 160 MW Laksefjorden 100 MW 3100 Digermulen 100 MW Hammerfest 110 MW Rakkocearro 350 MW Båtsfjord 120 MW Vannøya 135 MW Sørøya 15 MW Domen, 100 MW Raufjell 240 MW Skallhalsen, 65 MW Kvitfjell 200 MW Flatneset 35 MW Rieppi 63 MW Bugøynes 90 MW Andøya 260 MW Fosen offsh.: 600 MW Gimsøy 50 MW 3955 Straumøya 26 MW Sjonfjellet 428 MW 4605 Sleneset 225 MW 4855 Ytre Vikna 250 MW 4905 Hundhammerfjellet 48 MW 5655 Oksbåsheia 150 MW Harbaksfjellet 90 MW Bessakerfjellet 50 MW Roan 180 MW Frøya 200 MW Kvenndalsfjellet 120 MW Hitra 55 MW Div. Vindparker Fosen statkraft 720 MW Nygårdsfj. 40 MW Nord-Norge: Finnmark: 2900 MW Troms : 680 MW Nordland: 1025 MW Midt-Norge Trøndelag: Romsdal: 2210 MW Møre & 2215 MW Total around 9000 MW Smøla 150 MW 7285 Fræna 65 MW 895 Haramsfjellet 66 MW Haugshornet 75 MW

11 Wind development in a broader perspective Wind expansion

12 Extensive wind development scenarios Wind capacity may reach levels that are highly significant in relation to presently installed generation capacity Implies a major transformation of the Nordic Power System and its physical characteristics

13 Impact on central System Operator duties Balance regulation Load-frequency control Transmission Snitt MW Snitt MW Snitt MW

14 Balance regulation in hydro Efficient, emission-free MWh/h Already used today Import / - Export Vattenkraft Vindkraft Värmekraft Kärnkraft Elavändning Tor Fre Lör Sön Mån Tis Ons The regulation capacity of hydro power is extensive but not infinite Maximum use of the capacity is demanded to meet European needs In conflict with local environmental concerns

15 Demand flexibility - Smart Grids

16 Vehicle-to-Grid (V2G) Vision Based on vision from AC Propulsion

17 Development of Market and Regulatory Instruments > To incentivize development of efficient use of electricity > To transform dynamic market prices into effective demand flexibility > To share the economic profit along the value chain from system operation to the electricity end user

18 Enhanced transmission capacity needs > Transport of large volumes of renewable generation > Transport of back-up generation > Facilitate use of efficient and sustainable sources of balancing capacity > Equalize wind generation over large areas

19 European 10 year network development plan by ENTSO-E Total projects km AC < 300 kv AC > 300 kv 2900 km km 83% 17% 22% 56% long term 78% upgrade new 44% mid term DC 9600 km ~14% of existing transmission line km October 15,

20 South West Link, - a Smart Grids application An optimal technology combination with high capacity, around MW AC OH-line HVDC VSC Multiterminal

21 The NordBalt Interconnector Capacity Voltage Length 700 MW 300 kv ~450 km Technology VSC 21

22 TSO Requirements on Smart Grids Development of the existing power system by integration of modern transmission and information technology > High capacity grid reinforcements > More advanced system protection and control > Demand flexibility as a balancing resource
