To optimize generation costs we need to develop
cost relationships between net power out and operating
costs. Between 2-6% of power is used within the
generating plant; this is known as the auxiliary power
Best for most efficient units are
limits and the
In the graph shown below for each value of lambda
there is a unique PGi for each generator. This
relationship is the PGi() function.
