This paper addresses the existing need for training dispatchers in the
operation of power systems where it involves managing large water sys
tems. The problem formulation and implementation of water system model
ing for the Dispatcher Training Simulators (DTS) are presented in this
paper. The method systematically builds the water network description
s. The model periodically calculates the water system flows, storage v
alues, and currently available hydro generation capacities. The model
is controllable by the instructor and provides the simulated telemetry
of water system data to the control center functions in the DTS. The
water system modeling enhances the power system modeling subsystem of
the DTS. The method is validated on a large water system and power sys
tem data. The results and the benefits of water system modeling are di
scussed.
