Abstract: Optimal Power Flow (OPF) problem is one of the most widely nonlinear optimization problems in power systems. This paper proposes a novel hybrid optimization algorithm that combines the merits of salp swarm optimization (SSO) algorithm with particle swarm optimization (PSO) algorithm for solving the OPF problem. The proposed hybrid method is considered to accomplish economic, environmental and technical benefits. The proposed method is applied to single and multi-objective optimization problems with different objective functions such as generation cost minimization, emission reduction, transmission power loss minimization, voltage profile improvement, and voltage stability enhancement. To prove the capability of the proposed hybrid optimization algorithm, 18 case studies are employed and tested on three standard test systems. The proposed PSO–SSO algorithm achieves significantly the effectiveness and robustness of the OPF results for the cases considered. The simulation results demonstrate that the proposed method leads to superior levels of techno-economic-environmental benefits compared with those reported in the literature. In addition, the sensitivity analysis study confirms that the proposed hybrid method produces robust results against parameter variations.
