HVDC Back-to-Back interconnection between Turkey and Georgia is operational since November 2013. Previous feasibility analysis regarding to this project has shown that depending on the amount of power transfer between parties and loading conditions, there might be transmission bottlenecks and problems observed in Turkish Power System. In this respect, special protection coordination is required to maintain reliable and sustainable operation. In this thesis, design of a special protection scheme that coordinates outages in the region along with some countermeasures is introduced. The design study starts with analyzing critical scenarios and instabilities endangering the normal operation of Turkish Power System in order to define requirements of the special protection scheme. In this regard, static and dynamic analyses are carried out to identify instability patterns and solution spaces for critical instability conditions. The results have shown that regional system is highly vulnerable to the contingencies and may face regional collapse even without interconnection. Hence, several scenarios and several loading conditions have been analyzed in detail in order to give insight to special protection logic design and calculate countermeasures required for critical instability conditions. As a result of these studies, requirements for stable and sustainable operation of the region are specifically determined and a wide area measurement based special protection scheme is designed. In addition, modelling of the designed scheme in a power system simulation environment and simulation results of the proposed scheme are presented. Finally, coordination and compliance between existing protection measures with the proposed protection scheme are also investigated.

Optimal determination and allocation of secondary frequency control reserve in a market environment considering ACE criteria / Geren, Ali; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014) Frequency control in Turkey is realized under four main tasks, namely; primary, secondary, tertiary frequency control and time control according to European Network of Transmission Operators for Electricity (ENTSO-E) regulations. As being a part of an interconnected electricity network, secondary frequency control mechanism, which is realized by the utilization of an Automatic Generation Control (AGC) System, plays a crucial role in the achievement of two important goals. One of them is maintaining the freq...
Determination of optimum values for voltage setpoints of power stations in Turkey Elma, İsmail; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014) Voltage control is performed in three hierarchical levels in Turkish power system: primary, secondary and tertiary voltage control. Primary and secondary voltage controls are defined as the regulation of the voltage at the generator terminal and at the high voltage busbar of the power plant according to the pre-determined setpoints. The determination of the voltage setpoints for the power plants, which is defined as the tertiary voltage control, is performed by the operators in National and Regional Load Di...
Technical evaluation of synchronous interconnection between Mashriq Countries / Uysal, Gökhan Yasin; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014) The Electrical Interconnection among The Eight Countries Project (EIJLLPST Project) has been initiated by Mashriq countries (Libya, Egypt, Jordan, Palestine, Syria, Lebanon, Iraq) and Turkey. The objectives of the EIJLLPST Project are to investigate necessary investments to reinforce the existing interconnections and to increase transfer capacities between EIJLLPST countries. This study aims to evaluate the transfer capacities of the existing and planned interconnections between these countries through comp...
Measuring the efficiency of the turkish electric distribution sector using stochastic frontier analysis Çelen, Aydın; İyigün, Cem; Department of Industrial Engineering (2011) This study analyzes the technical efficiencies of Turkish electricity distribution companies (21 in total) throughout 2002 and 2009. For this aim, we used six different model specifications, all of which are generated from two different Stochastic Frontier Analysis (SFA) models (Battese ve Coelli (1992&1995)). At the end of the estimations of the models, it has been seen that the signs and significance levels of the coefficient estimations are very consistent and satisfactory in all models. We also observed...
Alternative feasibility studies for Altıparmak Dam and HEPP Ak, Mümtaz; Kentel Erdoğan, Elçin; Yanmaz, Ali Melih; Department of Civil Engineering (2011) Hydropower is the most important domestic energy source of Turkey. Thus, wise planning and development of the unused hydropower potential of the country is vital. There are many hydroelectric power plants under planning stage in our country. Altıparmak HEPP is one of them. General Directorate of Electrical Power Resources Survey and Development Administration (EİE) and ANC Enerji conducted two separate feasibility studies for Altıparmak HEPP in 2001 and 2009, respectively. Traditionally, the energy income c...
