| Abstract | Ship-board integrated power systems (IPS) play a crucial role in the all-electric ships (AES) initiative, where the power generation, conversion and distribution are done on a common electric platform. Along with many advantages of the IPS, its inter-connectivity presents a major opportunity as well a challenge for reconfiguration control. To ensure overall optimal performance while sustaining the critical ship service loads, the reconfiguration problem can be formulated as a trajectory optimization problem with the inputs to power sources as optimization variables. The high dimensional and nonlinear nature, along with the extended time horizon involved, makes many grid and gradient based methodologies infeasible for this application, especially when real-time requirements are considered. This paper, motivated by the IPS reconfiguration control, proposes strategies for improving the real-time computational efficiency of the IPS optimization by leveraging the time scale separation of its dynamics. The trade-offs between the computational efficiency and optimization accuracy are analyzed and a numerical example is provided to illustrate the effectiveness of the proposed algorithm. |

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.
