Optimal determination and allocation of secondary frequency control reserve in a market environment considering ACE criteria /

Geren, Ali
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 frequency at the nominal value while the other one is keeping the active power flow through interconnection lines at scheduled values. Challenge of achieving these two goals originates from the existence of rapidly vi changing loads which create significant deviations in the frequency of the network and undesired power flows on tie lines. In this thesis study, an iterative algorithm to determine the amount of reserve with minimum cost while satisfying the ENTOE-E criteria regarding Area Control Error (ACE) is developed. Cost minimization of the reserve support is conducted based on the price bids of the power plants participating in AGC system in the day-ahead electricity market. Satisfaction of ACE criteria is validated by dynamic simulations of a simplified ENTSO-E dynamic model including governor settings of the machines. As a result of these studies, amount of reserve to be held on an hourly basis is determined in a systematical way. Furthermore, allocation of fast and slow responsive reserve groups is determined for the use of system operators in National Dispatch Center.


Design of a special protection scheme and supplementary controls regarding HVDC back to back interconnection between Turkey and Georgia
Tanıdır, Özgür; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014)
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 coordin...
Assessment of the effect of hydroelectric power plants' governor settings on low frequency inter area oscillations
GENCOGLU, C; Tor, O.B.; Cebeci, E.; Yilmaz, O.; Güven, Ali Nezih (2010-10-28)
The Turkish TSO (TEIAS) has been leading a project that aims the synchronous interconnected operation of the Turkish Power System and the ENTSO-E CESA (former UCTE) System. For this purpose, this study concentrates on the specific problems related to the electromechanical systems of large size hydroelectric power plants regarding low frequency inter area oscillations, which are prone to occur once the interconnected operation is established. The expected frequency of inter area oscillations after interconne...
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...
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...
The liberalization of the Turkish electricity sector: a simulation analysis
Bahçe, Serdal; Taymaz, Erol; Department of Economics (2003)
The Turkish Electricity System has gone through a liberalization process. This study aims to analyze the possible outcomes of this process by using a simulation framework. First, we look at the basics of new market design and focus on international evidence. Second, the theoretical and empirical literature about the liberalization of the electricity sector is reviewed. Then, the structure of our model, Turkish Electricity System Simulation Model (TESS), is summarized. In this model, it is assumed that a spo...
