<br />. . (j:~u3Q3 <br /> <br />The Resident Power and Reservoir System Model (pRSYM) <br /> <br />Input Data Requirements <br /> <br />The general categories of input data required by PRSYM will include: <br /> <br />· simulation data <br />· reservoir system network data <br />· hydrologic data <br />· operating policy and constraint data <br /> <br />Simulation data includes run parameters or set-up information, initial and boundary <br />conditions, and other pertinent status information (e.g., current water surface elevations, <br />maintenance schedules, special operations, and/or generation estimates). <br /> <br />Reservoir system network data defmes the attributes of all the objects in the modeled <br />network. Some examples of this type of information include the network connections, <br />hydropower plant and unit characteristics, and geometric information (Le., volume-elevation- <br />area curves for reservoirs or reaches). <br /> <br />Hydrologic data include local inflow data for each reservoir (or reach) at the appropriate time <br />step. As discussed further in Section 4, local flow data must be available from several <br />different sources including the DSS modular hydrologic modeling system, a non-resident <br />utility-specific operational hydrologic modeling system, or historical flow files. PRSYM <br />must also be able to access statistical data such as median flow information. PRSYM must <br />be capable of utilizing multiple sequences of local flow time series data. <br /> <br />Operating policy and system constraints are embedded in functions, constraints, or operating <br />rules. This information defines the physical and operational constraints on the system, as <br />well as multipurpose operating strategy. <br /> <br />Output Parameters <br /> <br />For each project, at the appropriate time step, the simulation module must provide the <br />following primary output parameters: <br /> <br />· reservoir elevation <br />· dam release <br />· hydro plant generating capacity <br />· hydro plant generation <br />· hydro plant turbine discharge capacity <br />· spill <br />· project energy-in-storage <br /> <br />When appropriate (i.e., daily routing is utilized or the water quality module is employed), <br />the model must also provide at specified locations: <br /> <br />3-11 <br /> <br />"........ -------- <br />
