AB -    This  paper  presents  a  comparative  analysis  of  efficient  and  reliable  modern  programming 
approach  using  quadratic  programming  (QP)  and  general  algebraic  modeling  system  (GAMS)  to  solve 
economic  load  dispatch  (ELD)  problem.  The  proposed  methodology  easily  takes  care  of  different  equality 
and  inequality  constraints  of  the  power  dispatch  problem  to  find  optimal  solution.  To  validate  the 
effectiveness of algorithm simulations have been performed over four different cases i.e. Crete Island system 
of 18 thermal generating units, twenty generating units system with losses, practical Taiwan Power Company 
(TPC) data which consists of 40 generating unit system and a very large system consisting of 110 generating 
unit. Results obtained with the proposed method have been compared with other existing relevant approaches 
available  in  literatures.  Experimental  results  support  the  claim  of  proficiency  of  the  method  over  other 
existing techniques in terms of robustness and most importantly its optimal search behavior.
