1 Smartening the grid in praxis:
the next 15 years Tahir Kapetanovic Head of National Control Centre Austrian Power Grid AG 23rd WEC Energy Forum Zagreb, 28. November 2014

2 ~15 years from now …  organically grown fuels will be „No. 1“,
nano-machines will be cleaning cardio-vascular system, intelligent pills will be used in curing cancer, driverless cars will become common appearance on streets, nanotech will revolutionize photovoltaic use, today‘s ~50-years old will be (close to) retirement, EU climate & energy policy goals 2030 will be achieved.  ? Narrow-minded fear or justified concern ? ?!

3 What are we talking about
EU climate and energy policy goals 2030 („40% less CO2 in 2030 than in 1990“) & European electricity sector

4 Interconnected power systems of Europe (VIUs) 1990
The (grey) past Relatively easy to comprehend IT/data Security of Supply by politics Simple roles & responsi-bilities Conventional generation: no volatility & stability = OK Risk-free planning Only one kind of actors (VIU) „Self-susta-inability“ and simple merit order Simple roles & responsi-bilities Conventional generation: no volatility & stability = OK Risk-free planning Interconnected power systems of Europe (VIUs) 1990 Interconnected power systems of Europe (VIUs) 1990 4

5 The (colourful and challenging) present
Stability becomes an issue Plethora of actors Volatility risks 2014 (Security of) supply by market (?) ENTSO-E IEC xxx Common Grid Model & co. Load-curve & price structure changed

6 Electricity networks of the future (
The new smart future … dealing with overall IT complexity? … security of operation & supply in market? … roles & responsibili-ties? … generation mix challenge? … risk mana-gement? … non-discriminatory treatment of all actors? … „repairing“ (technically) new merit-order? ?!, and what about … 2030 Electricity networks of the future (

7 Generation mix Some generators are needed at their electrical / geographical locations to aleviate congestions; … others are needed for reserves; … and some are needed for ancillary services. Therefore, even when all RES is integrated in the electric power system, „system generators“ will be required

8 Risk management Trading volatility close to real-time: wind  power exchange Share the tasks  Regional Security Cooperation Initiatives for coordinated operational planning (load flows, (n-1), …) Source: Source:

9 Non-discrimination With (or even without – because of already high portion and massive further growth) market maturity, all generation, including wind and solar, shall be integrated according to the same principles and rules RES (wind & solar) shall also have chance / obligation to contribute to market activities & services In times of prevailing infeed (e.g. negative prices), a positive discrimination might be needed

10 „Repairing“ new merit-order
Local storage  incentives  market model Pmin (also 0 € / MWh) t Price (t) (z.B. EPEX Spot) Feed-in tariffs paid out (t) Wind generation (t) [MWh] t1 t2 Feed-in to the grid Feed-in to the storage (physical, contractual, …) Source: T.

11 New ancillary services beyond P/f, Q/V & Restoration
Inertia / rotating masses of synchronous generators are essential for system (frequency) stability after disturbances Replacement of (large) synchronous generators by wind & solar generation  reduced intertia Must-run synchronous machines, or Synthetic intertia, „complementary“ to the primary control § 15 of ENTSO-E Operational Security Network Code: Analysis  Methods  Deployment * Source: _future_grid_stability_w_PV.pdf *

12 Security of operation & supply in market
Coordinated phase-shifters operation Min. 1 hour before real-time no more Intraday changes In emergency (e.g Hz) TSO shall be granted access to all available / running generation in each control area, in all Member States Market model & framework must be adjusted to the new generation mix and market situation

13 Dealing with complexity
Common Grid Model („object oriented“)  ENTSO-E CGM Exchange Standard (Source: uments/140401_ENTSOE_CGMES_v2_4_13_rev_2.pdf#search=CGMES%20figures)

14 A glimpse on smart distribution (bidirectional flows!)

15 How much of wordwide CO2 could be affected?
Worldwide greenhouse gas emissions by region Total greenhouse gas emissions of EU MS by sector 0.13 * 0.31 ~ 4% (total electricity)  only a portion of that in EU electricity grids! Sources:

16 Concluding For ambitious EU energy policy goals, bold measures are required Only if all relevant sectors are addressed accordingly (e.g. transportation!) can we hope for success Electricity sector of Europe is responsible only for small portion of worldwide CO2, electricity grid part of it is indeed a tiny one The grids (especially transmission) are already smart, getting smarter and will contribute The outlined tools and framework for that are indispensable

17 Thank you for your attention!

18 No more „old“ merit-order
BACK No more „old“ merit-order Sun turns load curve upside-down Nuclear generation is being (or planned to become) phased out Phelix Peak/Base annual average Daily forward front-year Peak/Base Source: Peak-to-base spread dissapears Gas price takes gas- fired generation out of merit
