Figure 21.1 illustrates the linking structure for three Generator elements in a Power Plant Diversion. This approach allows the Power Plant Diversion to sum the Diversion and Depletion Requests to get a Total Diversion Requested and Total Depletion Requested. Alternatively, the Total Diversion Requested and Total Depletion Requested can be input directly by the user; however, it is often desirable to use one or more Generator objects for this purpose.
