Combined Economic Emission Dispatch With the Effect of Valve Point Loading Using Flower Pollination Algorithm

Economic Load Dispatch (ELD) is the process of allocating the required load between the generation units such that the operation cost is minimized. In this paper, Flower Pollination algorithm (FPA) is implemented to solve Combined Economic Emission Dispatch (CEED) problem in power systems. The CEED problem can be solved by summing the generation cost minimization and emission minimization by considering the weighting factor with the effect of valve point loading while satisfying the constraints. Results for various test system such as 3-unit and 10-unit system for generator cost minimization, emission minimization and for CEED with the effect of valve point loading are discussed.
