| Abstract | The DC bus voltage of the unified power flow controller (UPFC) is closely related to the active power balance between the series and the shunt sides. In this study, a highly reliable modular multilevel converter (MMC)-UPFC DC bus voltage control strategy is proposed to ensure the continuous and stable operation of the MMC-UPFC. The DC voltage coordinated control strategy of dual converters in the shunt side, which combines the constant DC voltage control, droop control and margin control, is based on the topology configuration of the main converter and the standby converter. The DC voltage coordinated control strategy is adopted for different control targets under conditions of small-range adjustment of active power flow, wide-range adjustment, and the shunt-side converter failure, to achieve reliable and stable operation of UPFC under different operating conditions. Finally, a simulation model was established under the MATLAB/Simulink environment to verify the feasibility of this control strategy. |

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.
