The project includes the development of a <br />Decision Support System (DSS), as well as an Integrated Modeling System to support <br />scheduling, forecasting, and planning functions of the DSS. This report specifies the <br />requirements for the Integrated Modeling System. To address the modeling needs of a <br />variety of electric utilities, the modeling system will include: resident models, non-resident <br />models, and analysis tools. Resident models, which will be directly incorporated into the <br />DSS, will include a power and reservoir system model and site-specific models. The <br />development of a generic power and reservoir system model (pRSYM) that will integrate <br />multipurpose reservoir operations with power system economic is a major project task. The <br />DSS will also support the inclusion of site-specific models to address operational issues at <br />particular power plants or river reaches. Additionally, to facilitate the use of existing utility- <br />specific operational and planning models with the DSS, these complex models will not be <br />directly integrated into the DSS but will be considered 'non-resident' models. Appropriate <br />links will be developed to enable sharing of data between non-resident models and the DSS. <br />Finally, a common set of tools will be provided to analyze results from resident and non- <br />resident models. The analysis tools will include capabilities to summarize model results; <br />evaluate system behavior with respect to performance criteria; portray multi-objective <br />tradeoffs; and provide general statistical analysis, graphics, and reporting utilities. <br /> <br />III <br />
