<br />O.~.ti1"l <br />UV':;!/ I <br /> <br />SUMMARY <br /> <br />Project Overview <br /> <br />The INTEGRAL Project is an Electric Power Research Institute (EPRI) and Tennessee <br />Valley Authority (TV A) collaborative effort to develop improved tools for the coordinated <br />scheduling and planning of power generation and multipurpose reservoir operations. The <br />project includes the development of a Decision Support System (DSS) and an Integrated <br />Modeling System that will be generalized for use by a variety of electric utilities and water <br />resource agencies. <br /> <br />The DSS will aid in the collection, analysis, and display of reservoir and power system data. <br />The primary functions of the DSS are to summarize current system status and forecasted <br />conditions, alert users to potential violations of critical thresholds or environmental limits, <br />and aid in reservoir and power system scheduling, forecasting, and planning. An integrated <br />system of models will support these scheduling, forecasting, and planning functions of the <br />DSS. This report specifies the requirements for this Integrated Modeling System. <br /> <br />Integrated Modeling System <br /> <br />To address the modeling needs of a variety of utilities and water resource agencies, the <br />Integrated Modeling System will be divided into three main categories: resident models, <br />non-resident models, and analysis tools. The functional requirements for each of these <br />categories are summarized below. <br /> <br />Resident Models <br /> <br />'Resident Models' are models that are fully integrated into the DSS, are always loaded when <br />the DSS is active, and are readily accessible by any DSS user. The DSS will include two <br />types of resident models: a Power and Reservoir System model and site-specific models. <br /> <br />Resident Power and Reservoir System Model. A major project task is the development of a <br />generic Power and Reservoir System Model (PRSYM) that can integrate multipurpose <br />reservoir operations with power system economics. As a scheduling and forecasting tool, <br />PRSYM will be used to develop reservoir schedules for the near term and on a seasonal basis <br /> <br />S-l <br />
