| Abstract | Micro-grids are formed on introduction of Distributed Generator(DG) units in conventional distribution systems. These micro-grids operate in either autonomous mode or non-autonomous mode. When line contingencies occur in micro-grids, there are chances for formation of accidental islands. This paper proposes an algorithm for forming controlled islands on occurrence of line contingencies in micro-grids, using the information about accidentally formed islands and line contingency ranking. Identification of such accidental islands has been attempted in this work, by tracing the change in the configuration of the autonomous micro-grids. Ranking of line contingencies is done with the database of the detected accidental islands. The proposed algorithm is also attempted for radial and weakly meshed structures based on the voltage profile, performance indices, line losses and transient stability of the DGs. MATLAB coding is developed to validate the proposed algorithm & the standard 33-node radial distribution system is used for validation of the proposed algorithm. |

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.
