11. With Iraq:
Construction of 400 kV Cizre (Turkey) - Musul (Iraq) interconnection line is
under bidding process.
• 400 kV Gercüş-Cizre-Border OHL (~130 km) will be tendered in 2011.
• 400 kV Cizre SS will be tendered at the begining of October 2011.
• Th investments will b fi li d at the end of 2012
The i ill be finalized h d f 2012.

12. With Syria:
600 MW Back to Back station is planned on the existing of
400kV Birecik –Aleppo interconnection line
Aleppo line.
New connection possibilities will be studied in order to increase
the energy export capability from Turkey to Syria and the
interconnected countries of Syria (Eight Countries project).

13. Queue Management
• Process:
1. The available capacity for connecting wind generations are published by
TEİAS.
2. WPP applications are forwarded to EMRA (Turkish Regulatory Agency) for
these capacities.
capacities
3. These applications are forwarded to TEIAS for studying connection
opportunities.
4. TEIAS gives its comment concerning the availability.If the application
g g y pp
is alone in the substation, EMRA gives license to those applications.
5. If there are multiple applications in one substation, compitition process
is done by TEIAS to determine the owner of the capacity.
6.
6 After taking license the investor sign a connection agreement with
TEIAS.
7. Project will be approved by MENR after the realization of the project
System Usage Agreement will be done with TEIAS.

15. Brief History of Queues
• Installed capacity of wind pp’s in operation are: 1588 MW
• Licensed wind power plants before 1 November 2007 applications: 3483 MW
• 1 November 2007 applications
pp
– Number of applications: 722
– Total capacity: 78.000 MW
• 8474 MW capacity has been published for these applications .
• Therefore TEIAŞ determineconnection point to wind power plants totally
amount of 12000 MW which is planned capacity of 2013.
• 71 application which h
li ti hi h have an i t ll d capacity of 2246 MW are alone at th
installed it f l t the
sellected substations. Licensing process is going on for theese applications.
• Competition process has been finalized for the substations where multiple
applications h b

18. Grid code of wind power plants
• The studies for revising the the g code for wind p
g grid power p
plants
are going on with Turkish Technological Research Enstitute(TUBITAK).
The final grid code for WPP’s will be send to EMRA till the end of 2011
WPP s 2011.

19. ENTSO-E interconnection
• What is the effect of ENTSO-E interconnection to the penetration of wind
power plants in Turkish Power System?
• By the ENTSO-E interconnection primary reserve requirement of Turkish
power system is decreased from 770 MW to 300 MW
– But secondary reserve requirement did not change by the ENTSO-E
interconnection and it is stayed as 770 MW.
– Primary and secondary frequency control of System leave its place to tie line
control of three 400kV interconnection lines between Turkey –Bulgaria and
Turkey-Greece .
• By increasing of wind power penetration in Turkish grid the secondary
reserve requirements will increase.
• The increment of Secondary reserve requirements will be performed by
hydroulic and natural gas power plants that the total percentage is
approximatey %70 in Turkish Power System.
19

20. Future Problems
• What will be the operation problems if ~11300 MW wind power plant will be
in service ?
• Wind applications are concentrated in west side of Turkey. This will cause
excessive voltage changes i the region
i l h in h i
• Effective regional voltage control ;
• Effective secondary reserve control will be needed.
• Effective ENTSO-E interconnection tie line control
• All th
these i
issues can b managed b an effective wind f
be d by ff ti i d forecast and
t d
monitoring system

21. We are not lucky as Germany for operating the system 

22. Future Efforts
• WIND FORECAST SYSTEM
The wind forecast system has been developed by Turkish State Meteorological Service which is
available to provide information about the wind forecasts for different heights and for 48 hours
with 4 km solubility all around Turkey.
• WIND MONITORING SYSTEM
Specific SCADA System for wind power plants is under developing process
