| Abstract | This paper deals with application of automatic generation control (AGC) to deregulated power system and makes a maiden attempt to provide a new practical AGC model to cater to the needs of a modern restructured hydro-thermal power system. Several DISCO Participation Matrix (DPM) and Area Participation Factor (APF) have been tried out and dynamic responses for frequency, tie flow and generations are obtained to examine the performance of the system in deregulated environment considering integral controllers. Investigation has been carried out to study the effect of generation rate constraint and the importance of APF in deregulated environment. Studies also reveal that the conventional integral controllers are quite robust and the optimum integral gains once set for nominal condition need not be changed for plusmn25% variations in system parameters and plusmn20% variations in operating load condition from their nominal values. The sensitivity of the optimal controller gains to DPM and APF has also been brought out. For the first time, studies have been carried out for the selection of suitable values for governor speed regulation parameter R for the hydro and thermal plants in the deregulated mode. System studies reveal the satisfactory operation of the hydro-thermal system conforming to the requirements in the deregulated environment |

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.
