2.5 ECONOMIC DISPATCH CONSIDERING LOSSES – THE CLASSICAL METHOD

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 r^th iteration as:

for i = 1, 2, …, n_g

We have the equality constraint

The r^th iteration values of P_i obtained from Eq.(2.23) are substituted in the above equality constraint equation.

That is,

where P^r_L is the total loss of the system ...
