Abstract | The Highly Optimized Tolerance (H.O.T.) model which aims to describe the statistics of robust complex systems in uncertain environments, is used to analyze the electric blackouts occurred on North America Power Grids. The cumulative probability of event size is taken into account as the index observing the law that the blackout follows. As the assumption of the existing work, the resources are optimally distributed with respect to the megawatts lost if the standard H.O.T model is well fit the statistic data. Therefore, the data from the Western power grid (western system coordinating council, W.S.C.C.), together with those from northeast power grid(Northeast Power Coordinating Council, N.P.C. C), ranging from 1984 to 1999 of all power outages occurring on the grids are used for comparison. These data are measured in the size of megawatts lost. In applying the model to the power grid data, we observe that the model agrees closely with the W.S.C.C. data but not exactly the N.P.C.C data. One of the possible explanations is that that the optimal resource distribution of power grid is valid for the W. S. C. C but not the N. P. C. C. However, another possibility is that the existing standard H.O.T model is still not a generic model in terms of power system application. In this sense, a power-system-objected model is worth studying for the purpose of direct instruction using H.O.T. theory as the tool of power system blackout mechanism analysis and countermeasure. |

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.
