Electronics, Journal Year: 2024, Volume and Issue: 13(22), P. 4563 - 4563

Published: Nov. 20, 2024

The increased integration of renewable energy sources (RESs), such as photovoltaic and wind turbine systems, in microgrids poses significant challenges due to fluctuating weather conditions load demands. To address these challenges, this study introduces an innovative approach that combines Unscented Transformation (UT) with the Enhanced Cheetah Optimization Algorithm (ECOA) for optimal microgrid management. UT, a robust statistical technique, models nonlinear uncertainties effectively by leveraging sigma points, facilitating accurate decision-making despite variable generation conditions. ECOA, inspired adaptive hunting behaviors cheetahs, is enhanced stochastic leaps, chase mechanisms, cooperative strategies prevent premature convergence, enabling improved exploration optimization unbalanced three-phase distribution networks. This integrated UT-ECOA enables simultaneous continuous discrete decision variables microgrid, efficiently handling uncertainty within RESs Results demonstrate proposed model significantly improves performance, achieving 10% reduction voltage deviation, 10.63% decrease power losses, 83.32% operational costs, especially when demand response (DR) implemented. These findings validate model’s efficacy enhancing reliability efficiency, positioning it viable solution optimized performance under uncertain inputs.
