| Abstract | The micro grid is a cluster of electricity generators, energy storage systems, and loads that can operate connected, as well as disconnected, from the distribution grid. In this paper the time related characteristics of Cyber Physical Systems (CPCs) to be used for (IEC 61850-based) automation of micro grids are investigated. Specific constrains are taken into account as, for instance: the use of heterogeneous communication networks; the reuse of any existing wired and wireless network and assets; and the deployment of new renewable power sources or energy storage systems into traditional (old) grids. The proposed approach relies on IEEE 1588 infrastructure placed in the key positions of the Micro grid to build a backbone for precise distribution of time reference to IEC 61850 device, (which are used to guarantee the interoperability with the distribution grid). The proposed solution is installed inside the campus of the University of Brescia in a real micro grid. The experimental results show the feasibility of the proposed approach, with overall latency and jitter in good agreement with the usual requirements of IEC61850: for instance, the total estimated end to end delay (latency) including the backbone (i.e. 3 cascaded Ethernet switches) is below 0.6 ms. |

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.
