A Practical Approach to an Interim Multi-Area Economic Dispatch Using Limited Computer Resources

A straight foward and computationally efficient method is presented for calculating and sending "economic" Area Control Error(ACE) signals to three operating companies in the Texas Utilities(T.U.) System. The method requires T.U. system ACE and each operating company\´s total generation and then mathematically computes each area\´s desired generation. The difference between the desired generation and the actual generation for each area is it\´s economic ACE.
