| Abstract | With rapid development of DC microgrid (DCMG), the protection against short circuit fault on the whole DC system has gained widespread concern. This paper proposes an approach which uses power electronic transformer (PET) and fault current limiters (FCLs) to improve the impact of short circuit current in DCMG. FCL in the fault line can work in the fault current limiting mode to limit short circuit current in this line. PET adjusts the input power from AC grid to DC grid to keep the DC voltage stability in the DCMG. A complete model of PET and DCMG is developed and the collaborative control strategy of PET and FCL is analysed. The simulation results confirm that the proposed control strategy based on the collaborative operation of PET and FCL can enhance the ability to ride through the short circuit fault of each part of DCMG system. |

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.
