“…Rao algorithms have been successfully used by researchers in the short time since they have been introduced, some of which include the engineering design optimization ( Rao & Pawar, 2020a ; Rao & Pawar, 2020b ; Rao & Pawar, 2022 ; Rao & Pawar, 2023 ), weight optimization of reinforced concrete cantilever retaining wall ( Kalemci & Ikizler, 2020 ), cropping pattern under a constrained environment ( Kumar & Yadav, 2019 ), construction scheduling ( Yılmaz & Dede, 2023 ), photovoltaic cell parameter estimation ( Premkumar et al, 2020 ; Wang et al, 2020 ), optimization of energy systems ( Rao et al, 2022 ), and optimal power flow ( Sahay, Upputuri & Kumar, 2023 ).…”

Many important engineering optimization problems require a strong and simple optimization algorithm to achieve the best solutions. In 2020, Rao introduced three non-parametric algorithms, known as Rao algorithms, which have garnered significant attention from researchers worldwide due to their simplicity and effectiveness in solving optimization problems. In our simulation studies, we have developed a new version of the Rao algorithm called the Fully Informed Search Algorithm (FISA), which demonstrates acceptable performance in optimizing real-world problems while maintaining the simplicity and non-parametric nature of the original algorithms. We evaluate the effectiveness of the suggested FISA approach by applying it to optimize the shifted benchmark functions, such as those provided in CEC 2005 and CEC 2014, and by using it to design mechanical system components. We compare the results of FISA to those obtained using the original RAO method. The outcomes obtained indicate the efficacy of the proposed new algorithm, FISA, in achieving optimized solutions for the aforementioned problems. The MATLAB Codes of FISA are publicly available at https://github.com/ebrahimakbary/FISA.

The optimization of reactive power dispatch involves controlling and managing reactive power in power grids to uphold desired voltage levels at the buses. In recent days, the traditional thermal generators within power grids are being substituted by renewable energy resources (RES) like solar and wind facilities. The paper focuses on solving the Optimal Reactive Power Dispatch (ORPD) problem by integrating solar and wind power plants into power networks, using the Hybrid Whale and Sine Cosine Optimization Algorithm (HWSCOA). Within the IEEE 30-bus system, solar and wind power plants are put in place of two thermal generators at bus 5 and bus 8. Uncertainties in load demand, wind power, and solar power are addressed using probability density functions and a set of scenarios. The objective is to minimize power losses of transmission lines and voltage deviation. A scenario-based technique is employed here to represent uncertainties, generating a collection of 30 scenarios that consider uncertainties in load demands and power from solar and wind sources. The ORPD problem is defined as an optimization problem with the goals of diminishing power losses in transmission lines and minimizing voltage deviation. The results show a reduction in power losses and minimized voltage deviation with uncertain demand, wind, and solar power.
