Abstract | Dynamic VAR planning for voltage stability enhancement is a challenging topic for power systems with a growing penetration level of wind power. As a critical step of VAR planning, candidate bus selection (CBS) can reduce the scale of the problem and improve the optimality of the planning decisions. This study proposes a new zoning-based CBS method towards multiple voltage resilience indices. First, a set of resilience-oriented metrics are proposed to comprehensively evaluate voltage performance in pre-contingency and post-contingency stages, considering the extent of the voltage deviation and voltage recovery time, as well as the post-contingency steady-state voltage profile. Then, a zoning-based approach is developed based on fuzzy C-means clustering and Morris screening to categorise buses into different zones with capacity sensitivity analysis. Finally, a comprehensive multi-objective CBS scheme is proposed for voltage resilience enhancement. Simulation results show that, compared with conventional approaches, the method can achieve more voltage stability improvement with the fewer or the same number of candidate buses. |

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.
