| Abstract | Two of the most frequent causes of power system voltage instability are voltage recovery following faults, and voltage collapse during transient swings. We propose methods for the identification and mitigation of these phenomena by appropriate usage of control devices such as dynamic VAr sources. We also propose a method for the reliable simulation of these phenomena, called "the time continuation method". This method combines the efficiency of power flow techniques and the capabilities of transient stability models. It is based on a quadratic model of the power system, including generators, voltage regulators and dynamic loads consisting mainly of induction motors. This model explains recently observed voltage stability and voltage recovery phenomena. Numerical experiments with visualizations are presented for the purpose of quantifying the phenomena and identifying the major affecting parameters. It is shown that proper combinations of static and dynamic reactive power sources can alleviate the risk of voltage instability. Finally, we propose a methodology for selecting the location and size and mix of static and dynamic VAr resources for the purpose of alleviating the risk of voltage instability and slow voltage recovery |

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.
