| Abstract | The ever increasing demand and restriction on having additional new infrastructure, forces the existing power system network to work at its maximum possible limits. In order to increase the power transfer through given infrastructure, the use of FACTS devices is common and very well known. Here a Model Predictive Control based TCSC controller is used for improving the transient stability response of a single machine infinite bus system (SMIB). The system model is used to formulate a quadratic optimization problem to help find out the required capacitive compensation from series connected TCSC in a given line. Considering the nonlinear and hybrid nature of power system a Non-Linear Model Predictive Controller (NMPC) is designed. The major contribution of this paper is the use of NMPC strategy for TCSC controller to enhance transient stability of SMIB system considering a detail system model with 10 variables. Since system model considered here is non-linear in nature, NMPC allows the use of a non-linear model instead of using a linear model for prediction. Also, NMPC helps to increase the region of attraction, which allows system to come back to healthy conditions even after the fault is removed beyond critical clearing time. For reasons mentioned above, the method suggested here appears to have an edge over other methods employing linear model and controllers for SMIB system. The concept and theory is supported by simulation on SMIB system with nonlinear model predictive based TCSC controller. |

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.
