System Analysis of the Turkish Power System for Interconnection with Continental Europe

This paper presents the modelling, phasor analysis, model validation and simulation study for primary control power allocation of the Turkish power system. With these studies the simulations were performed to investigate the ability of the Turkish power system to become interconnected with the European Network of Transmission System Operators for Electricity-Continental Europe (ENTSO-E-CE). Extensive investigations and measures in the Turkish power system were performed in order to ensure the compatibility of both systems and a stable parallel operation. The challenges were the changeover from the previous island operation to the future interconnected operation, the high share of hydraulic units in Turkey power system and the system extension leading to longitudinal structure. Due to the resulting system dynamic characteristics, the primary control power of at least 300 MW has to be provided by thermal units and the turbine control of hydraulic units had to be adjusted. These studies were performed and the results are successful. All the models were created using MATLAB/SIMULINK software. On 18 September 2010 at 9h25 (CET) the Turkish power system was synchronized with the interconnected power systems of Continental Europe via three lines to Bulgaria and Greece.
