An integrated approach to simulation of a hydro system called HYDROMOD has been developed and used to place a value on additional energy-limited peaking hydro capacity added to a major electric utility in the Southeastern United States. The hydroelectric project to which the capacity was added must operate under severe operating restrictions placed upon the magnitude and duration of its water discharges into the receiving river. The model was developed and run in a PC environment. It integrates the simulation of system hydrology and hydraulics, reservoir operation, 'real' dispatch procedures, load uncertainty, other similar power resources serving the same load, and all operating constraints that affect the hydraulics and dispatch of the resource. The use of the model to accurately reflect real-world conditions resulted in greatly reduced values of the effective load carrying capability than would have been indicated by production costing models such as POWRSYM.
