Deregulated power market congestion management

The transmission network represents undoubtedly the infrastructure that enables the power market. Nowadays operating conditions of the power systems, open access to the transmission network, leading to different transactions within a certain power system or cross-border transactions, are increasing the risk of congestions. Taking into consideration these facts, new tools are necessary to be developed, according to the actual conditions. This paper aims to elaborate an original mathematical model used for congestion management in case of deregulated environment. In the following, a software tool is developed in Matlab environment, designed for probabilistic congestion management. The West and South-West power system is used as a case study.
