| Abstract | The Icelandic power system is based primarily on hydroelectric and geothermal generation. The system has large resources compared to the size of Iceland's economy. The main utilization practice for electrical energy hitherto has been bulk Energy Intensive Industry (EII) with relatively flat and constant load. A possible future interconnection to neighboring countries via High Voltage Direct Current (HVDC) submarine cable could affect dramatically the operations planning framework, for instance with possibilities of linking to wind power, local and/or foreign and short term markets. This should affect factors such as operation strategies for hydro system and the planning and operations tools needed to realize this rent. Planning tools and modeling for hydro dominated systems may in some respects inherently be more complex than those of thermally dominated systems, due to the time-interdependence associated with reservoir storage and various constraints [4]. In this paper we give an overview of historical and current modeling practices used both as a tool to form system expansion policies and operations strategies in the long, medium and short term. The basic time frame requirements for such tools are discussed in this paper and how the may evolve in the future in terms of methodology and other important issues. Conclusions will be drawn regarding these planning tools and the future planning and operations framework in such a system, especialy the time frame issue. The long and medium term hydro-scheduling problem has been investigated since in the early part of the 20th century [14], applying various optimization and iterative simulation methodologies. The practices applied in the Icelandic system have traditionally been based on Scandinavian approaches, such as those originally suggested by [9], [17] and [2]. These methods in hydro dominated systems have been based on an iterative calculation of water value tables based on iterative dynamic programming like algorithms. Future methodology may involve LP or SDDP [16], but with a short term considerations (DTM, see below) to certain extent as outlined in this paper. |

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.
