| Abstract | Microgrids with a variety of distributed generations (DGs) are very common in modern power system. When a fault occurs in the power system, the microgrid will operate as an isolated grid to ensure security. Then DGs were separated from the microgrid and the measures of load shedding were taken accordingly. When the fault is cleared, it is important to restore the whole network and as much load as it can. An optimal restoration strategy for the microgrid is proposed here. Firstly, the objective for the network recovery is to have a shorter recovery time and the mathematical model is to seek the shortest path. The Dijkstra's algorithm is a classical method to solve the optimal path problem which can be applied in the microgrid network restoration to find the shortest path from a given source node to every other node. Also, analytic hierarchy process method, which is a structured technique for organising and analysing complex decisions, can help select the source node. Then, when a bus is recovered in the microgrid, the load on the relevant bus should be considered to recover. Finally, a microgrid including DGs and diverse energy storages is used to illustrate the effectiveness of the proposed method. |

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.
