Enhanced Maximum Power Point Tracking for Hybrid Solar and Wind Systems Using Fractional-Order Constant Voltage Topology: A Novel Approach in Power Electronics

The growing demand for renewable energy has led to the integration of solar and wind systems as sustainable power sources. Efficient energy harvesting from these systems requires precise tracking of the maximum power point (MPP) under varying environmental conditions. The integration of solar and wind energy systems is vital for achieving sustainable power generation. The objective of this research is to develop an efficient Maximum Power Point Tracking (MPPT) technique that addresses the variability of environmental conditions in hybrid solar and wind systems. This study introduces a novel approach using Fractional-Order Constant Voltage (FO-CV) topology for MPPT. The proposed method leverages fractional-order calculus to enhance the adaptability and accuracy of traditional MPPT techniques. In this approach, the constant voltage technique is applied to maintain the system's operating point near the Maximum Power Point (MPP) under fluctuating solar irradiance and wind speeds, while the fractional-order controller ensures improved dynamic response. Simulation results demonstrate that the FO-CV topology outperforms conventional MPPT methods, achieving faster convergence to the MPP, higher energy efficiency, and greater system stability. The findings highlight that the FO-CV method not only optimizes power extraction but also reduces fluctuations in power output during sudden changes in environmental conditions. The novelty of this approach lies in the combination of fractional-order control with constant voltage tracking, which provides a more robust and adaptable solution for hybrid renewable energy systems.
