ABSTRACT

The process simulation equations for hydrosystems applications basically consist of the governing physical equations that simulate a physical process such as conservation of mass, energy, and momentum. Many problems for the operation of hydrosystems can be formulated in a general optimization framework in terms of state variables and control variables. The existing nonlinear programming codes cannot solve such large, sparse problems. The class of problems that are being considered in this book essentially have a large number of partial differential equations or other simulation equations as part of the constraint set making them more complex than the standard type of optimization problem. These optimization problems are referred as optimal control problems. Reservoir system operation is for the purposes of meeting water supply demand and recreation demands, maintaining minimum flow levels for navigation and environmental concerns, and providing flood protection, power production, and flood control.
