Operational security analysis of interconnected european network in liberalized market

This paper discusses the problems of operational security analysis in context of a large power system consisting of international boundaries and heterogeneous electrical markets with different levels of liberalization. After analyzing the requirements of the operational security analysis, the paper presents the mechanism, which has been used to make a consistent network model for roughly 20 participating countries. The operational security analysis is split into several sub-problems, which include N-l security analysis in day-ahead time frame and in on-line mode for operations. The computation of network transmission capacity in advance and optimization of network operating condition in planning or on-line are also facets of the network security analysis. Since the security analysis process is mission critical, a method has been developed using state of the art information technology tools to automate the exchange of model and merge of data models from different participants.
