This study presents a comparative analysis of various optimization algorithms—Differential Evolution (DE), Particle Swarm Optimization (PSO), Arithmetic Algorithm (AOA), and Hippopotamus (HOA)—for parameter identification in photovoltaic (PV) models. By utilizing RTC France solar cell data, we demonstrate that accurate estimation is crucial for enhancing the efficiency PV systems, ultimately supporting sustainable energy solutions. Our results indicate DE achieves lowest root mean square error (RMSE) 0.0001 double-diode model (DDM), outperforming other methods terms accuracy convergence speed. Both HOA PSO also show competitive RMSE values, underscoring their effectiveness optimizing parameters research not only contributes to improved precision but aids broader effort advance renewable technologies, thereby fostering more future.

This paper introduces a novel and improved double-resistor damped double-tuned passive power filter (DR-DDTF), designed using multi-objective optimization algorithms to mitigate harmonics increase the hosting capacity of distribution systems with distributed energy resources. Although four different topologies single-resistor filters (DDTFs) have been studied before in literature, effectiveness two DR-DDTF configurations has not examined. work redresses this gap by demonstrating that via comprehensive simulations on systems, provides better harmonic suppression resonance mitigation than alternatives. When it comes optimizing for maximum minimum system active losses, artificial hummingbird outperformed six other benchmark. To allow higher penetration generation without requiring grid upgrades, newly developed good alternative.
