| Abstract | The objective of this work is to present a decision support system that determines the optimal dispatch strategy of gas fuelled thermal power plants taking into account the particular specifications of fuel supply contract agreements, such as take-or-pay and make-up clauses. Opportunities for energy purchase and selling at the electricity spot market as well as detailed modeling of the power plant such as maintenance cycles and influence of ambient temperature in the plants efficiency are also considered in the optimization. In an integrated way, the model also determines the plants' optimal schedule for maintenance. Since decisions in one stage impact the future stages, the problem is time-coupled and multi-stage. Moreover, the main driver for the operations decision-making is the electricity spot price, which is unknown in the future and is modeled in our model through scenarios. Therefore, the optimal dispatch strategy is a stochastic problem requiring decision under uncertainty, where at each stage the objective is to determine the optimal operation strategy that maximizes the total revenues taking into account technical constraints and the clauses of the fuel supply contract. The methodology applied is the stochastic dual dynamic programming (SDDP). A case study in the Brazilian system will be 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.

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.
