Economic and emission load dispatch using Cuckoo search algorithm

Abstract

To examine the optimal power output for all the generating units the economic load dispatch problem in a power system is used by which will decreases the total fuel cost whereas fulfilling all practical constraints. Since optimal economic dispatch is not globally the excellent solution so such it was required to reduce the toxic waste or emission dispatch problem. The Combined Economic Emission Dispatch problem is formulated as bi-objective problem by considering both fuel cost and emission concurrently. By using price penalty factor the bi-objective Economic and Emission Dispatch problem is converted into single objective problem. Here, to resolve the combined economic-emission load dispatch problem an effort has been performed using Cuckoo search algorithm, where CSA have number of application and it is a useful tool developed for optimization in engineering. On the basis of the obligate brood parasitic behavior of some cuckoo species this algorithm is explained. In this paper, Cuckoo Search Algorithm (CSA) method is used to obtain the best optimal solution considering for Combined Economic and Emission dispatch problem for simple six unit test system.
