ECONOMIC EMISSION LOAD DISPATCH WITH LINE FLOW CONSTRAINTS USING A CLASSICAL TECHNIQUE

A maiden attempt is made to explore the feasibility of developing an a pproach to,solve the economic emission load dispatch (EELD) problem wi th line flow constraints using a classical technique based on coordina tion equations. The inability of the classical technique to handle the line flow constraints so far is circumvented innovatively by expressi ng the line flows in terms of active power generations through distrib ution factors. These distribution factors are elegantly developed from existing load flow information using a perturbation technique. The pr oposed model based on the classical technique for EELD is tested on IE EE 14- and 30-bus test systems and the results are compared with those obtained by quadratic programing, the Hessian method, the Ricochet gr adient method and the linear programing method.
