With the increasing concern over environment protection, economic and environmental power dispatch has become one of the active research areas in the power system operation and control. It is essentially a Multi-Objective Optimization Problem, which minimizes both fuel cost and emission pollution simultaneously without violating the operational constraints. To solve this problem, this article presents a new hybrid algorithm based on kernel search optimization (KSO) and sparrow search algorithm (SSA) (HKSOSSA). The proposed HKSOSSA optimization algorithm is employed to solve IEEE 6-unit EED problem. The results show that the proposed HHKSOSSA algorithm for EED problem can obtain a better trade-off between fuel cost and emission objectives compared to those reported algorithms in the recent literature.
