It regards the problem of hydrothermal generation dispatch as the problem of dynamic optimal control, and infers the general form which is the sensitivity of optimal control solutions to initial conditions to request water value of the hydrothermal generation problem. The full differential method of our inference is use Augmented Lagrangian method. It regards this optimal control problem which relaxes all constraints except system dynamic equations as a dynamic optimal control problem of no constraints. We infer an easy method which requests the sensitivity of optimal control solutions to initial conditions successfully, and apply this result to examples of hydrothermal generation system. From mathematical inference and application, the full differential method of our inference which requests the sensitivity of optimal control solutions to initial conditions is easy, reliably and effectively.
