Dynamical modelling and simulation of a cascaded reserevoirs hydropower plant

The cascaded reservoirs hydropower plant is a complex nonlinear system that involves interacting input and output nonlinear parameters, nonlinear flow rates, and nonlinear dynamical hydraulic heads. It needs an exclusively designed supervisory control and optimization system. In this paper a new dynamical model for a cascaded hydropower plant is developed. The developed model is accurate enough to represent and simulate the plant nonlinear dynamics and to design the control system. It may enable a control system designer or a plant operator to carry out accurate computer simulations for the cascaded reservoirs hydropower plant under a wide range of operational modes and nonlinear process conditions.
