Solving Environmental/Economic Power Dispatch Problem by a Trust Region Based Augmented Lagrangian Method

This paper proposes a trust-region based augmented method (tralm) to solve a combined environmental and economic power dispatch (eepd) problem. the eepd problem is a multi-objective problem with competing and non-commensurable objectives. the tralm produces a set of non-dominated pareto optimal solutions for the problem. fuzzy set theory is employed to extract a compromise non-dominated solution. the proposed algorithm is applied to the standard ieee 30 bus six-generator test system. comparison of tralm results with the various algorithms, reported in the literature shows that the solutions of the proposed algorithm are very accurate for the eepd problem.
