In spite of the benefits of the implementation of the power market, the biggest threats for the security and safe working of power grids still rests in the congestions of cross-border lines, as well as the network itself. The occurrence of the congestion is a result of the limited network transfer capacities that are result of increased power transactions. There are other measures that can mitigate the congestion, but still it is a problem and cancelling or lowering the power transactions should be no solution. This problem arises from the assumptions and simplifications made in the methodologies for total transfer capacity calculation which reflects to unreal cross-border capacities. In this paper, we propose an iterative optimization algorithm for a total transfer capacity calculation in case of market-based units, which consider the reactive power flow and all the constraints that, comes forward. The results and the conclusion that shall be presented in this paper are made on the IEEE test network, RTS_96.
