This study presents a novel approach for optimizing Maximum Power Point Tracking (MPPT) command in an wind energy conversion system (WECS) utilizing an Permanent Magnetic Synchronous Generator (PMSG).A proposed method integrates Ant Colony Optimization (ACO) to enhance power extraction efficiency. Specifically, a Proportional Integral (PI) controller is employed for steady a maximum power point for a wind turbine, yielding crucial parameter values 'P' and 'I' within a stable range. To tackle conflicting closed-loop system performance criteria, a multi-criterion ACO approach is utilized, focusing on Mean Squared Error (MSE) for controller settings. Simulation results demonstrate the successful attainment of the desired Maximum Power Point, evidenced by outputs such as generated power, DC bus voltage, electromagnetic torque, and current. That innovative approach offers a comprehensive strategy for optimizing MPPT control at wind energy systems, contributing to enhanced overall performance and efficiency. ©2024 IEEE.

The increasing demand for renewable energy sources underscores the need for efficient DC/AC power converter. This paper offerings the scheme and implementation of controlled two-level three-phase inverter aimed at regulating and supplying power from renewable sources such as solar, wind, and hydroelectric. Utilizing IGBT technology, the inverter is customized to provide power to 3-phase balanced star connected load through a passive filter. Its operation is governed by two regulation loops: one for the voltages produced at the AC output and the other for the currents flowing through the input inductor of passive filter. The control approach, developed using Matlab-Simpower Systems, is executed on the eZdsp TMS320F2812 DSP board. Experimental validation involves comparing the effectiveness of bidirectional DC/AC converter with those of a compact industrial module, 7MBR15SA120. The comparison demonstrates a close alignment between the experimental waveforms of the two prototypes, confirming the effectiveness of the proposed control strategy. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

The organic-inorganic perovskite solar cell shows great promise among third-generation solar cells due to its cost-effective fabrication and rapid efficiency improvement. In this study, we present the reconstruction of a solar cell utilizing a structure consisting of copper-graphene-perovskite sulphur ( ) with a configuration. Graphene, known for its exceptional properties, holds substantial potential as a material for next-generation photovoltaic solar cells. Employing the SCAPS-1D (solar cell capacitance test system one-dimensional), we examined the effective thickness of the perovskite layer and its impact on solar cell performance. Our findings reveal that an optimal thickness of and a band gap of resulted in an efficiency of . The top-performing solar cell exhibited an (fill factor) of , (short-circuit current density) of , and (open-circuit voltage) of . These results suggest that , as a p-type semiconductor material, could play a crucial role in advancing solar energy conversion through perovskite absorption. © 2023, The Authors.

This manuscript introduces an innovative Maximum Power Point Tracking (MPPT) strategy to improve the efficiency of Wind Energy Conversion Systems (WECS) equipped with Permanent Magnet Synchronous Generators (PMSG) under variable wind conditions. The proposed approach integrates Active Disturbance Rejection Control (ADRC) with the Perturb and Observe (P&O) algorithm, effectively addressing challenges such as external disturbances and fluctuating wind environments. By combining ADRC with P&O control, the system achieves enhanced tracking performance and *** validate the added value of this approach, we compare it with a traditional P&O strategy combined with Proportional Integral (PI) control. For the PI-based method, controller parameters Kp and Ki are optimized using Genetic Algorithm (GA) and Ant Colony Optimization (ACO) to enhance control precision. The Integrated Time Absolute Error (ITAE) objective function is employed to fine-tune these parameters, further optimizing system performance. Our analysis underscores the superiority of ADRC in disturbance rejection and quick adaptability over the PI *** proposed strategy is tested under two distinct wind speed profiles—constant and fluctuating—through time-domain simulations in MATLAB/Simulink. Simulation results confirm the superior performance of the ADRC-P&O method, highlighting its effectiveness in maximizing power extraction from wind energy and proving its potential for real-world applications. This study offers a significant advancement in wind energy technology by providing a robust and efficient solution for MPPT in WECS. © 2024
