| Abstract | The traditional transient instability analysis method based on time-domain simulation without considering future uncertainties has some limits in practice, so a transient risk assessment method based on trajectory sensitivity is proposed in this paper. The contingency cost is considered as minimum control cost to move the system from instability to stability, and the sensitivities of relative rotor angle with respect to output of generators and dispatchable load are employed to properly consider the transient stability constraints in the optimal power flow (OPF). The minimum objective of OPF is the determination of contingency cost. With the load curtailment and control cost produced by OPF, some instability risk indices are obtained. The correctness and effectiveness of the presented method is finally validated by New England 39-bus system. |

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.
