| Abstract | The complexity of the power grid structure and its operating mode has greatly enhanced, increasing the probability of the large-scale blackout. Identifying the vulnerable lines in the process of cascading failure plays an important role in adopting effective suppression strategy to ensure the safety and stability of the power grid. An frequent pattern (FP)-growth algorithm-based method of identifying vulnerable lines in large power grid is proposed in this study. Based on the model of operational reliability, the cascading failures are simulated and chains of failure are generated. This study mines the sets of failure chain to discover the frequent items in the sets and to identify the vulnerable lines in the development process of cascading failures. Also, this study analyses the risk of vulnerable lines and its impact on cascading failure. Simulation results of IEEE118-Bus benchmark show that the proposed method can identify dangerous lines in the development process of chain fault effectively, which is important for suppressing the cascading failures and reducing the power failure probability. |

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.
