| Abstract | Reactive power plays an important roll as an ancillary service in the new power system structures. Without an appropriate reactive power and voltage control the transfer of active power could not be done. The restructuring of the electric sector carried out in the last years in various countries gave rise to competitive markets of electric energy, giving main attention to the active power. Nevertheless, compared with it, the calculation of costs and prices for reactive power is not a clearly defined and solved matter. In this work a methodology to calculate prices based on the theory of marginal costs of active and reactive power and in techniques of decoupled optimization is presented. This one allows finding economical signals of active and reactive power at a nodal level, which may help to define pricing criteria of transport costs of reactive power and to detect responsibilities among transmitters and distributors in the generation-consumption of reactive power. For the decoupled optimization model the operation costs minimization and the transmission losses minimization were used as objective functions. In this work, the trend in dealing with the reactive power, the situation in the Argentinian market, the main methodological state and some results of applications on the Argentinian high voltage power system (SADI), are presented. |

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.
