Developments of Turkish grid system infrastructure for integration with Europe

In a globalizing world, dominating and the shaping energy sector can be achieved by satisfying energy quality criteria and having a structure to meet the criteria specifies international standards. Voltages, frequencies, waveforms, outages, harmonics and flicker effects are the parameter of quality criteria in a grid system. Among them, the frequency is the most important parameter in production of high quality energy. Frequency control provides load demands and keeps the system in balance. Synchronization of Turkish grid system with Continental Europe grid systems were first started by signing an agreement between the Turkish Transmission System Operator and European Network of Transmission System Operators for Electricity (ENTSO-E), Transmission System Operators (TSOs), Hellenic Transmission System Operators (HTSO), Electricity System Operator (ESO-EAD), Amprion and Tennet GmbH (former Transpower) on 18 September 2010. The synchronization of Turkish grid system to Europe transmission system has been achieved from two different points, Bulgarian and Greek, over 400 kV power lines. This paper analyses the synchronization criteria of Turkey and neighboring countries as well as the criteria for energy quality.
