Niagara Mohawk Power Corporation (NMPC) presently manually schedules their hydro system of 660 MW (80 stations in ten river basins). The scheduling procedures are labor intensive and relatively inflexible. Little extra time is available to test schedules, or respond to changes in streamflow or demand predictions. A research and development demonstration project is being conducted in a 200 square mile basin for NMPC to develop an integrated system for improved hydro scheduling using real-time hydromet data, streamflow forecasting models, and optimization and simulation models. The real-time hydromet network consists of 6 monitoring stations sampling hourly measurements of streamflow, precipitation, soil moisture, snow depth, and 8 other hydrometeorological parameters. Particularly attractive features of the system model are (1) the capability to use variable time steps, (2) its interaction with a simulation model which allows users to fine-tune the model's output based upon their experience, and (3) user-friendly I/O screens and procedures which not only show the results of the models but also allow for the production of reports.
