Situation adapted display of information for operating very large interconnected grids

This paper addresses the problem of security monitoring and situation awareness in very large interconnected transmission systems, with particular emphasis on the continental European grid. An innovative approach of situation adapted displaying of the operational state of a large network is proposed, which is based on state-of-the-art cognitive methods. This approach is able to be processed online and makes the displays available to all participating transmission system operators. The proposed approach for an improved situation awareness of different security threats such as wide-area split of the system and cascading overload is applied with a very large simulator model of the continental European transmission system of about 15,000 buses.
