| Abstract | Voltage instability can be mitigated or avoided by coordination of appropriate control resources. In addition, to meet the power quality requirements, it is desirable to find the whole minimal-cost trajectory using available controls without violating any constraints. This is the trajectory optimization problem and intrinsically hard to solve in power systems because of the interactions between continuous dynamics and discrete or continuous controls. The hard constraints also add to the complexities. In this paper, the trajectory optimization problem is formulated as a mixed-integer quadratic programming (MIQP) problem which can reduce the computation burden. Due to the open-loop characteristics, this formulation will be subject to uncertainty and the system may not evolve as expected. However, the proposed framework embeds the MIQP formulations into receding horizon control (RHC) to compensate for uncertainties such as model error, disturbances, and noise. As a result, reasonable computation speed and improved accuracy are obtained. |

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.
