| Abstract | In the last few years, the electric sector has been going through the unbundling process of several participating agents and to the creation of a responsible market for all the occurring transactions. One of the services of great importance within this new electric sector is that pertaining to the services that contribute to the security, reliability and quality of the power supply. Such a group is referred to as ancillary services. Among the various types of ancillary services, spinning reserve is a service necessary for maintaining the integrity of the transmission system from either generation interruptions or load variations. This paper uses the application of the economic dispatch theory with the objective of financially quantify the availability of supplying spinning reserve in hydroelectric systems. The proposed methodology utilizes the generating units as well as their efficiencies so as to attend the total demand with the minimum water discharge. Thereafter, this value of demand is compared to that related with the dispatch which was realized following the guidance of the system operator. The difference in efficiency valorizes the availability for providing active spinning reserve. The proposed methodology was tested through the data provided by the Agua Vermelha hydroelectric power plant. |

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.
