Afandi, A.N. Abstract. 2023. This paper presents an application of Harvest Season Artificial Bee Colony (HSABC) algorithm to solve an Economic Load Dispatch (ELD) of power system operation throughout a Combined Economic and Emission Dispatch (CEED) problem. The IEEE-30 bus system is adopted as a sample system for testing the problem. The simulations showed that statistical, numerical, and convergence results of the HSABC are better than the existing tested methods. The proposed method of the HSABC seems strongly to be a new promising approach for solving an ELD throughout the CEED problem.
