Both the economic dispatch of thermal units and the hydrothermal dispatch are relatively simple problems. However, the transmission grid introduces additional constraints. Let us consider, for example, a power system with three operation areas, as shown in Figure 1.3.

Figure 1.3 Economic dispatch by areas considering network constraints with the transport model.

Each line has a maximum power flow capacity that introduces additional constraints in the model (both economic dispatch and hydrothermal dispatch). This constraint limits the flow among areas and modifies the results. These aspects are studied in Chapter 7 from a classic perspective and later, in Chapter 10, under a modern view based on conic optimization.
