| Abstract | With extensive access of distributed energy resources and DC loads, the traditional 10 kV AC distribution network has greatly increased the number of converters and reduced the reliability of power supply. A solid-state transformer (SST) containing AC and DC terminals to build AC/DC hybrid distribution networks has become the focus of the current research. This study presents an AC/DC hybrid distribution network structure with 10 kV AC, 10 kV DC, ±375 V DC, and 380 V AC four voltage levels. In this network, the load is data centre, which needs high security for power supply reliability. According to the characteristics of this network, this study takes the reliability evaluation by using the minimum path set method and the state enumeration method, and the reliability of this new structure with SST is calculated. Through the study of a numerical example, the results show that after adding the multi-terminal SST, the reliability of the AC/DC hybrid distribution network is suitable for data centre load, and the quantity of the converters can decrease. |

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.
