Abstract | Existence of distributed generators (DGs) makes it possible to split distribution systems into multi-microgrids (MGs) in emergency conditions. In this study, after optimal allocation of distributed generation sources with a multi-objective function, the test system is optimally sub-divided into some self-adequate MGs with the least not supplied active and reactive power during large-scale events. By using the proposed method, the network will be more resilient against large-scale events such as critical lines outages or big generation outage under natural events with the optimal voltage regulation for each MG. The multi-objective problem is solved by the fuzzy satisfying approach and Pareto optimality methods. The proposed method in this study is based on the exchange market algorithm and tested on two systems, IEEE 33- and 69-bus distribution systems. Also, under normal network conditions, operation of distribution networks is evaluated using different objective functions like micro-virtual networks with minimum power exchange and loss minimisation, to determine which function causes the network to have the best status in terms of reliability and resiliency. Obtained results confirm the efficiency of this method for partitioning distribution systems to increase network robustness before a fault occurrence and also improve reliability and resiliency after a fault occurrence. |

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.
