| Abstract | Modern power systems are extensively interlaced with data communication at various levels leading to increased vulnerability to cyberattacks at individual components as well as integrated controls. An effective cyber protection is, therefore, fast becoming an indispensable requirement for the smart grids. A false data injection (FDI) attack on load frequency control (LFC) is a stealth process, which has devastating consequences while at times may also lead to catastrophic system blackouts. This work comprises detailed analyses of the LFC system vulnerability to FDI attacks. It further develops an efficient event-triggered detection scheme to leverage the LFC protection against FDI attacks. This developed event-triggered generalised extended state observer (ET-GESO) uses Lyapunov stability analysis to derive the event-triggering condition and thereby reduce the communication burden significantly. The feasibility of the proposed ET-GESO is further studied by demonstrating its Zeno behaviour exclusion. Extensive simulation studies are performed on a peer-reported two-area power transacting system and IEEE 39-bus New England system. A comparison study between the proposed technique and reported Kalman filter-based detection scheme is also performed. Different FDI attack formulations and their detection illustrate the effectiveness of the proposed detection method. |

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.
