Abstract | This paper presents a preventive control method lowering cascading outage risk in large-scale AC-DC interconnected power grids. The method consists of two steps. Firstly the possible cascading outages are simulated using fast dynamics of OPA model. Then, a cascading outage risk based security OPF (COR-SOPF) is proposed, which minimizes overall load power outage risk of cascading outages. In COR-SOPF model, the risk of cascading outage is estimated using the data obtained from cascading outage simulation and risk assessment. The risk in this model is load outage power, its physical meaning is clear. The preventive control can notably lower the cascading outage risk. Effectiveness and practicality are verified by IEEE-118 equivalent system and China provincial system cases. |

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.
