Abstract | This paper presents an energy-based hybrid control, which replaces the traditional automatic voltage regulator (AVR) for excitation control of a synchronous generator connected to an infinite power system. The proposed controller is based on energy representation of the power system by using a port-controlled Hamiltonian form. The controller uses a hierarchical hybrid architecture characterized by continuous-time dynamics at the lower level of the hierarchy and logical decision-making units at the higher level of the hierarchy. The lower-level units, i.e., the subcontrollers, are each designed for a power system operating mode and directly interact with the power system to be controlled; while the higher-level decision-making units perform logical checks that identify system mode of operation and activates the corresponding lower-level unit; the activated lower-level unit then executes continuous control actions for the power system. Consequently, the controller can adapt to different power system operating modes. Simulation studies are carried out to show the effectiveness of the proposed controller for excitation control of the synchronous generator. |

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.
