| Abstract | This paper implements recursive least square method with variable forgetting factors (VFFRLS) in local real-time voltage stability monitoring scheme based on the application of Thevenin equivalent model and PMU to reform the existing methods which present weak performance in tracking the time-varying parameters of equivalent model for power system. The selections of variable forgetting factor and initial value, identification of the time-varying parameters of system component models, and condition of locking are discussed. The IEEE 39-bus system is used to validate the method. Simulation results show that this approach provides more accurate results in tracking the time-varying parameters. The numerical results also show that the design of locking conditions can deal with the typical contingency, such as large generating unit or transmission line tripped, to achieve more reliable real-time voltage stability monitoring. |

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.
