This paper proposes a comprehensive OPF model that incorporates conventional thermal generators, solar photovoltaic generators, and hydroelectric power generators, while effectively addressing the uncertainties associated with renewable power generation. A lognormal probability distribution models solar irradiance variability in solar generators, while a Gumbel distribution captures water availability fluctuations in hydro generators. The paper proposes a novel hybrid optimization approach, hybrid osprey-salp swarm optimization (HOSSO), to solve this complex OPF problem. The HOSSO leverages the exploration–exploitation balance of Osprey Optimization alongside the adaptive leadership and follower dynamics of Salp Swarm Optimization. The proposed methodology is validated on Institute of Electrical and Electronics Engineers 30-, 57-, and 118-bus test systems across five distinct optimization scenarios: economic cost minimization, emission cost minimization, combined economic–environmental cost minimization, voltage deviation penalty cost minimization, and renewable generation uncertainty penalty cost minimization. The model incorporates reserve and penalty costs for renewable generation uncertainty and integrates carbon emission taxation to enhance grid reliability and sustainability. Comparative analysis against classical and hybrid optimization techniques demonstrates the superior performance of HOSSO across most test scenarios, consistently achieving competitive solutions while satisfying system constraints and stability requirements. The algorithm delivers improvements ranging from 0.4% to 17% in cost minimization, 3%–23% in voltage deviation minimization, and 2%–8% in uncertainty management over competing methods, with performance advantages becoming increasingly pronounced as system scale grows. The algorithm exhibits rapid convergence within 20–50 iterations, effectively avoids local optima, and proves well-suited for both single- and multiobjective OPF problems in renewable energy-integrated power systems. The results highlight HOSSO's potential for real-time power system applications and its adaptability to smart grids with high renewable energy penetration.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"14 7","pages":"3346-3387"},"PeriodicalIF":3.6,"publicationDate":"2026-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70536","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the technical, environmental, and economic feasibility of developing a small-scale wind farm near GolGohar Sirjan Mining and Industrial Company, Sirjan, Kerman Province, Iran. Two complementary data sets were analyzed: measured meteorological data from the GolGohar station for the period 2020–2023 and long-term satellite-based data from the EMD International A/S-Weather Research and Forecasting model Middle-East model covering 1994–2019.

Alongside the technical evaluation, environmental impacts including noise, visual disturbance, and shadow flicker were analyzed, and economic viability was assessed by calculating the levelized cost of energy (LCOE) with a sensitivity analysis on the discount rate. Results show generally low-wind conditions, with an overall average of 4.6 m/s at hub height, and site-specific wind classes ranging from Class 1 to Class 2. Chahmil Village (T5, Class 2) demonstrates the highest potential, producing 205.1 MWh/year with a 23.4% capacity factor (CF).

Economic evaluation yields a baseline LCOE of 311.2 €/MWh, varying from 229.1 to 404.6 €/MWh depending on the discount rate.

The proposed method is designed not only to ensure optimal current and torque control but also to significantly reduce common-mode voltage (CMV). CMV is considered one of the main challenges in motor drive systems because it can lead to increased electromagnetic interference, bearing leakage currents, and a reduced lifetime of electrical and mechanical components. To address this issue, a simplified two-vector MPC method that applies two nonzero switching vectors at each sampling instant was developed. This approach was designed to improve stator current total harmonic distortion (THD) while reducing computational burden and system complexity. First, the three-phase two-level inverter and PMSM dynamics are modeled, and then an MPC controller is designed to simultaneously maintain high-quality current/torque control and reduce CMV. The effectiveness of the proposed simplified two-vector approach is validated through MATLAB/Simulink simulations and experimental implementation on a digital signal processor–based hardware platform.
