MULTIOBJECTIVE OPTIMAL POWER DISPATCH

Abstract

Economic load dispatch problem allocates loads to plants at minimum cost while meeting the constraints. It is done by an optimization problem which minimizes the total fuel cost of all committed plants while meeting the demand and losses. There are various objectives of power system- cost of generation, transmission losses and environment pollution etc. In this work the cost of generation and transmission losses have been considered as objectives for optimization. The multiobjective optimal power dispatch (MOPD) problem is formulated using weighting method and a number of noninferior solutions are generated in 2D space by varying weights for IEEE 5, 14 and 30 bus systems. Ideal Point (IP) is one where all the objectives are minimum and it is impossible to achieve this point because of conflicting nature of the objectives therefore an attempt is made to minimize the Euclidean distance between the Ideal Point (IP) and set of noninferior solutions. This gives the Target Points...
