Consider the two-bus power system shown in Figure \ref{twobus}, where the two nodes represent two markets, each with different total demand $D_i$, and one generator at each node producing $P_i$. At node A the demand is $D_A =2000\si{\mega\watt}$, whereas at node B the demand is $D_B =1000\si{\mega\watt}$. Furthermore, there is a transmission line with a capacity denoted by $F_{AB}$. The marginal cost of production of the generators connected to buses A and B are given respectively by the following expressions:
Assume that the demands $D_A$ and $D_B$ are constant and insensitive to price, that energy is sold at its marginal cost of production and that there are no limits on the output of the generators.
