| Abstract | Cyber-physical systems are pervasive in every walk of life. The safety performances of these systems are threatened by external malicious attacks and unforeseen failures. In terms of grid structural characteristics and graph theory, this study proposes a new framework to solve the problem of structural vulnerability which is caused by undetectable attacks in power grids. Based on the linear continuous-time descriptor system model, the digraph associated with structural matrix model for power grid is introduced in detail. To analyse the attack detectability in digraph, a series of basic properties are proposed about digraphs of structural power grids. Then an algorithm is proposed for obtaining the positions of the detection outputs to ensure left-invertible and observability for grid systems. In addition, an algorithm for judging whether there exists a structural vulnerability for the arrangement of the attack inputs and outputs of power grids is proposed, by which one can find disjoint paths if there exists structural vulnerability. Finally, some examples are shown to verify the effectiveness of the proposed algorithms. |

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.
