Abstract
This paper presents Ant
Lion Optimization (ALO) algorithmffffor solvingfffEconomic Load Dispatch
(ELD) problemfffwith practical constraints. ALO is a newly developed
optimization algorithm, which draws inspiration from mimics, the huntingfffmechanism of antlions in
nature. The antlions have a unique hunting mechanism and exhibit high
capability of reaching global optima, exploring the search space to find the
optimalfffsolution within a low computational time. For
practical ELD problem needs to take care about the characteristics of
generators, and their operational constraints, such as ramp rate limits,
prohibited operating zones, generation operating limits, transmission loss,
valve-point loading and non-linear emission functions. In order to validate the potency of the proposed method, four case
studies are investigated on different 6-unit systems and correlated with
recently published ELD solution methods. The results of the present work shows
that the proposed ALO is dominant than other
methods to finding out optimal results. Stastical analysisfffof the results among 30
trails has beenfffcarried out to validate the ALO as a highly potent
method. This algorithmfffis considered to be a promising best alternative
algorithm for solving the ELD problemff in power systems.
