An Experimental Study of Ion Motion Optimization for Constraint Economic Load Dispatch Problem

This article implements the Ion-Motion Optimization (IMO) optimizer to solve non-convex economic load dispatch (EcLD) problem in power system. The concept of Ion motion optimization is modeled from the attraction and repulsion forces among anions and cations in the real world. The mathematical model of IMO is quiet simple and very easy to implement. The liquid phase of IMO performs exploration and crystal phase simulates the exploitation. To handle the power balance equality constraint, exterior penalty method is used. Finally, EcLD problem having 13-generators is solved using ion motion optimization.
