Optimal Load Dispatch Using Ant Lion Optimization

This paper presents Ant lion optimization (ALO) technique to solve optimal load dispatch problem. Ant lion\ud optimization (ALO) is a novel nature inspired algorithm. The ALO algorithm mimics the hunting mechanism of\ud ant lions in nature. Five main steps of hunting prey such as the random walk of ants, building traps, entrapment of\ud ants in traps, catching preys, and re-building traps are implemented. Optimal load dispatch (OLD) is a method of\ud determining the most efficient, low-cost and reliable operation of a power system by dispatching available\ud electricity generation resources to supply load on the system. The primary objective of OLD is to minimize total\ud cost of generation while honoring operational constraints of available generation resources. The proposed\ud technique is implemented on 3, 6 & 20 unit test system for solving the OLD. Numerical results shows that the\ud proposed method has good convergence property and better in quality of solution than other algorithms reported\ud in recent literature
