Solving economic load dispatch problem using hybrid Krill Herd algorithm

This paper proposes an effective hybrid Krill Herd algorithm to solve Economic Load Dispatch problems. Effects of valve-point loading, prohibited operating zones of thermal plants are studied. System transmission losses as well as various equality and inequality operational constraints have also been considered. Numerical results exhibit that the proposed technique, involving crossover and mutation operators, is able to provide better solution than several techniques present in the literature, in terms of generation cost. Furthermore, this algorithm is better in terms of robustness than most of the existing algorithms used for this study.
