| Abstract | After the recent blackouts and incidents in Europe and USA, e.g. in 2003 and 2006, an increasing interest in security issues of multi-area power systems has arisen. The challenge is coordination of transmission systems operators that are responsible for their own control area but not for the whole system. Coordination is needed because often the transmission system operators have limited information on the neighboring control areas. Therefore, contingencies occurring inside one control area may not be noticed in other areas without appropriate coordination among transmission system operators even though they may have severe consequences. In this paper, we show that lack of coordination among transmission system operators may lead to insecure operation of the multi-area power system even though transmission system operators find their own control areas secure and show that security of single control areas may not imply security of the whole multi-area system. The results indicate that in order to ensure a secure operation of a multi-area power system, coordination and data exchange among transmission system operators should be improved in the future compared with the situation at the moment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
