Abstract | A reasonable recovery strategy for power system is important for the rapid recovery of the grid after a large-scale blackout. Based on the idea of timing restoration decision and taking into account the influence of extreme weather, a restoration strategy of power grid is proposed to avoid the affection of extreme weather on selecting transmission paths and generators and minimise the risk of a secondary failure in system recovery. Firstly, the recovery model of power elements in the case of extreme weather is established, and the improved Dijiestra algorithm is used to find the optimal path of the target generator. Secondly, the dynamic ordering of the generators is carried out considering the maximum power generation capacity during the grid recovery time, where the effects of various safety constraints and extreme weather on outputs of generators are taken into account. The validity and practicability of the proposed method are verified by the IEEE30 node system and the actual Guangdong power grid. |

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.
