9 WIND POWER IN TURKISH GRID

10 TURKISH WIND POTENTIAL The techno-economic wind potential of Turkey is 48 GW, according to General Directorate of Renewable Energy. The locations with highest potential are in the Aegean, Marmara, and Eastern Mediterranean and Hatay. 10

11 WIND INSTALLED CAPACITY LAW ABOUT UTILIZATION OF RENEWABLES 11

12 INSTALLED & PLANNED WPP s WPP STATUS MW IN OPERATION 2,890 HAS CONNECTION AGREEMENT with TEIAS 3,043 LICENSED by EMRA 3,422 PERMITTED for CONNECTION 1,192 EXTENSIONS APPROVED 974 TOTAL

13 INSTALLED CAPACITY PROJECTIONS In accordance with the Ministry of Energy s Strategic Plan, Turkey is targeting 20,000 MW installed wind-power capacity by the end of

14 MILESTONES FOR WIND IN TURKEY The law on the Utilization of Renewable Energy Sources (RES) for the purpose of generating energy, (Law No of 10/05/05) is the first Renewable Energy Law of Turkey which was approved in the year 2005 by the Turkish Parliament. In November 2007, the Turkish Energy Market Regulatory Authority (EMRA) accepted 751 WPP applications with total capacity of 78,000 MW. 14

15 NOVEMBER 1 ST 2007 APPLICATIONS Before Nov Singular WPP applications and licensed seperately 3500MW of Wind capacity allocated before Nov NOVEMBER 1 ST 2007 Nov Applications 722 applications with MW capacity Overlapping, or same region. ASSESMENT OF APPLICATIONS Integration of wind capacity equal to 25% of maximum total demand is planned to be integrated. ( /4=~ MW) Wind Basin Substations are planned in region with high wind energy potential. WPP applications are directed to nearest substations. Maximum capacity connectable to a BUSBAR is determined to be %5 of the Short Circuit MVA 15

16 WPP BASIN (COLLECTOR) SUBSTATIONS In region where wind potentials are high, Wind Basin Subs are planned to be established and connectable WPP capacities are announced by TEIAS to integrate WPP s.

17 WPP CONNECTION REQUESTS MANAGEMENT Nov Applications TM TM TM MW is decreased to MW Non-overlapping applications to different substations are classified as singular application and connections approved. No competition 2000 MW Applications that are overlapping or/and have connection request to same substation are assessed via competitions (bidding process) according to contribution fees. (tender fee) via competitions 5500 MW 17

18 WPP REQUIREMENTS For higher wind penetration levels, additional requirements for are added to grid code. Requirements for WPP s Connection requirements for Wind Power Generations are defined in the Appendix-18 of the Turkish Grid Code. Issues covered: Fault Ride Through Capability Active Power Control Frequency Reaction Of The Wind Power Plants Reactive Power Capacity Reactive Power Support Monitoring Of Wind Power Plants 18

19 WPP REQUIREMENTS Fault Ride Through The wind turbines shall stay connected to network when voltage at the Connection Point stays in the region 1 and region 2. Reactive Power Capability At the network connection point, the wind power plant must be capable of continuous operation for the power factor values in the region defined with the bold lines. FRT=1.5 s 19

20 WIND POWER MONITORING & FORECAST CENTER With increasing Wind Power installed capacity, it becomes important to forecast wind generation accurately to minimize daily-hourly deviations for dispatch and market. WPP Monitor & Forecast Center Licensed all the WPP s are obliged to establish necessary infrastructure to provide the monitoring of the wind farm from Wind Power Monitoring and Forecast Center (RİTM), developed by General Directorate of Renewable Energy. WPP s will be monitored also from Dispatch Centers for forecast and system operation. 20

21 FUTURE CAPACITY ALLOCATIONS For new wind power plant applications, 3,000 MW connectable capacity is announced by in December Applications for this capacity will be taken by EMRA in April These capacities are announced as regional capacities since substation based capacities do not allow larger projects. 21

22 NEW REGULATION REGARDING CONNECTION In the previous grid code, a capacity up to 5 % of the system short circuit MVA at the connection point is permitted. According to new regulation that has been published in January 2013, IEC standard is applied to determine wind power capacity that can be connected to busbar. 22

23 SOLAR POWER IN TURKISH POWER SYSTEM

24 TURKISH SOLAR POTENTIAL According to Strategy Paper of Energy Ministry, Turkey s aim in solar energy is to have MW solar power plant integration by

25 DETERMINING SOLAR INTEGRAITON CAPACITY Total connectable capacity for solar power plants is declared as 600 MW. Total installed capacity is distributed regarding the provinces, according to total average annual radiation and sunshine duration. Applications for this capacity are taken by EMRA in June After technical evaluation of these applications, capacity auctions will be carried out by. The first auction was realised in 12 th May
