For fast and effective solution of the economic dispatch problem the following method which uses the gradients is proposed.
Recall the Eqn.(2.23) of rth iteration as:
for i = 1, 2, …, ng
We have the equality constraint
The rth iteration values of Pi obtained from Eq.(2.23) are substituted in the above equality constraint equation.
where PrL is the total loss of the system ...
