| Abstract | The increasing wind penetration levels in today's power systems are creating challenges for system operators when maintaining adequate system reliability. Since ancillary service requirements are usually based on historical performance and engineering experience, a tool which could assess the system reliability status and determine when additional services are needed would be very beneficial for system operators, especially for systems experiencing large wind fluctuations. In this paper, an approach is proposed to assess the operational system generation adequacy by considering the generators' forced outages, the load forecasting deviations, and most importantly the wind forecasting deviations. The objective of this approach is to present a quantitative method of evaluating the hourly and daily reliability risk levels on a day-ahead and hour-ahead basis. Using probabilistic methods, an operational reliability assessment tool is developed to assist system operators in identifying high risk periods and making the necessary adjustments to ensure acceptable levels of system reliability. |

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.
