Abstract: A computer-implemented method of closed-loop dissolved oxygen monitoring and control at a hydroelectric plant includes: regulating at least one aeration valve coupled to a turbine using pattern recognition; wherein a target parameter for the regulating is a dissolved oxygen concentration of water downstream of the hydroelectric plant. The dissolved oxygen concentration may be at least 5.0 milligrams per liter. The pattern recognition may be performed using a neural network.

Abstract: A computer-implemented method of unit scheduling optimization for a hydroelectric plant in a bilateral market includes: minimizing flow of water through the hydroelectric plant to meet a generation schedule, wherein integer linear programming is used for the minimizing and a set of constraints used for the minimizing includes a minimum dissolved oxygen concentration downstream of the hydroelectric plant. The minimum dissolved oxygen concentration downstream of the hydroelectric plant may be at least 6.0 milligrams per liter. The hydroelectric plant may include at least two turbines disposed in the flow of water in a cascading arrangement.
