A system consists of two plants connected by a transmission line and a load that is located at plant 2. Data for the loss equation consists of the information that 100 MW transmitted from plant 1 to the load results in a loss of 10 MW and
where B11 is the only non-zero loss coefficient. Assume that the
incremental fuelcosts can be approximated by the following
equations:
Find the required generation for each plant and the power received by the load when ? for the system is $6 per Mwh.
