Maintaining a balance between electric power used by the consumers and that produced by power plants is one of the fundamental conditions of the safe operation of power systems, closely linked to the requirement to maintain system frequency within strict limits. This requires balancing power to be available continuously.

MAVIR ZRt. (Magyar Villamosenergia-ipari Átviteli Rendszerirányító Zártkörűen Működő Részvénytársaság) is the transmission system operator in Hungary. In Hungary MAVIR is responsible for the procurement and the economical utilization of control reserves considering operational reliability. Due to the liberalization of the electricity market it is already possible to purchase balancing power from neighboring control areas.

In my thesis I introduce the principles of power regulation, and I compare the Hungarian and Slovakian reserve markets. After the examination of how secondary control was implemented in the Hungarian system I introduce the International Grid Control Cooperation (IGCC) and after these the e-GCC co-operation which was created using the German model.

Finally, I summarize the experiences of the one-year test period when Hungary was taking part in e-GCC and being aware of all these information I add my proposals for future developments in Hungarian related Grid Control Cooperation systems.
