Congestion management approach after deregulation of the Slovenian power system

A congestion management approach that is going to be implemented in the Slovenian power system is presented in the paper. The method is based on countertrade approach where the system operator decides the optimal re-dispatch of power production, which eliminates congestion using the available technical and economic data. For that, relation between line power flow and each generator power production should be known. For this purpose, generalized generation distribution factors are used, enabling utilization of the linear programming technique to obtain optimal re-dispatch.
