The Economic Load Dispatch (ELD) has a very important role to play in the power system. There are various methods which include conventional and non-conventional methods, like lambda iteration, etc. But now a day's soft-computing techniques are more frequently used, as they can be applied to practical applications. Eco Bat Algorithm is nature-inspired for solving CHPED (Combined Heat And PowerEconomic Dispatch) problems involving non-smooth, non-convex, and non-linear problems.CHPED problem aims to determine ideal heat and power, satisfy the constraints and minimize the overall cost of the...
