Interchange Capacity between Portugal and Spain

Methodology, Evolution and its use in the MIBEL environment

Rui Pestana

2nd International Conference on Electrical Engineering

Coimbra, 28 November 2007


1. Methodology• ETSO• REN & REE

2. Evolution• Structural (investments)• Not Structural (investigation)

3. Use• Yearly : 2001-2006• Monthly : Jan-Nov 2007

o MIBEL (>1-Jul-2007)



ETSO – European Transmission System Operator

• TTC – Total Transfer Capacity• NTC – Net Transfer Capacity

o NTC = TTC – TRM

• TRM – Transmission Reliability Margin• AAC – Already Allocated Capacity• ATC – Available Transmission Capacity

o ATC = NTC – AAC

Methodology – ETSO


1. Parallel Flows• It is not possible to define an NTC for all pairs of

countries

Methodology – Limitations


2. Program versus Physical• The generation Shift is not equal to Physical flow

change at the tie-lines

Methodology – Limitations

o NTF – Notified Transmission Flow

o TTF – Total Transfer Flow


• Generation Shifto Start with base case including some Import/Export flowo Increase Generation on system A

Limited by Generation Capacity

o Decrease Generation on system B

Methodology – Computation


• Export of Portugal– It maybe limit Generation capacity in Portugal– The hydro (run-of-river) is not mobilized– The renewable (wind) is also not mobilized



• Import from Spain– There is no limit in the Generation capacity, since we

may import from France (in theory)



• Generation Shifto No load changeso TSO A computes

For Generation in A It uses economic merit order (economical signal)

For Generation in B It uses pro-rata order (no economical signal)

These differences may be justified because the limit from A to B computed by A is different from the computation by B.

• In ETSO all TSO must provide reference save cases (winter and Summer) Where all network elements are available (not realistic)



• Summer and Winter NTC in Europe

www.etso-net.org



• New procedure on the Iberian Methodology– Horizons– Time date to deliver data and results– Unavailability of network and generation

• That influence the Interchange Capacity• More realistic than ETSO

– Generation order merit• More realistic than ETSO

Methodology – REN and REE


• New procedure on the Iberian Methodology– TRM - Transmission Reliability Margin

10% of the Capacity with a minimum of 100 MW Covers errors on the network model used for the computation Covers Load forecast errors Covers Renewable Generation forecast errors

– Network security rules for each TSO Contingency analysis is also applied in foreign network Each TSO checks its network limits

Overload in foreign network is ignored Different results may show up !



• Horizons– Yearly

• REN : Monthly discrimination (ERSE, Hydrology)• REE : Season discrimination

– Trimester• Work day and weekend peak and off-peak discrimination

– Monthly• Daily peak and off-peak discrimination

– Weekly• For two weeks• Hourly discrimination



• Firmness (situation before MIBEL)

• PTR – Physical Transmission Rights– After the Capacity is given in the daily market, if there is

a need to reduce the interchange capacity, the TSO uses “counter trading” to guarantee the Transmission Rights

• Auction

– “Use it or get paid for it”

• Upgrade in Douro corridor– New Substation at International Douro

• Lagoaça : 400/220 kV

– To avoid the loop flows– New 400 kV Line



• Uprating on Tagus corridor



• New tie lines– Algarve



• High Speed Rail– Requires 400 kV

• Double phase load• Needs a very high short circuit

current



• High Speed Rail– Porto – Vigo

• Will increase Import Capacity• Populated region



• High Speed Rail– Évora – Badajoz



• Situation in 201?– 8 x 400 kV– 3 x 220 kV



• When we solve the “bottleneck of the tie-lines” we get congestions on the internal lines– Uprating

• From 50ºC to 75ºC

• From 50ºC to 85ºC

• From Bear to Zebra

• From Zebra to Zambeze

– Upgrade• From 150 kV to 220 kV

• From 220 kV to 400 kV

MIBEL – Iberian pool

Market Split – Why?

• If the Interchange Capacity is limiting the Market, it will split the Iberian Market and we have two market prices: Portuguese and Spanish.

Conclusions

• What is the amount of interchange capacity need for MIBEL ?– In the beginning, the prices are too different, thus we

need more capacity than what we have– In the end, when we have the same price, zero capacity

is enough– New players installing additional generation in Portugal

will decrease the pressure (2009/2010)

• What is the target of the Iberian TSO (REN and REE) ?– 3000 MW in the next decade
