Carrier PWM for Solar Power and SVPWM for Wind: A Synergized Control Strategy for Hybrid Systems

Abstract

In this study, we propose a coordinated control scheme for solar-wind hybrid power systems that use space vector pulse width modulation (SVPWM) for wind power and carrier pulse width modulation (PWM) for solar power. The proposed approach is designed to enhance energy efficiency, stability, and power quality in hybrid systems, addressing the challenges of variability in renewable energy sources. Carrier PWM is implemented for the solar power system to regulate the operation of photovoltaic inverters, ensuring optimal energy conversion under varying solar irradiance conditions. Simultaneously, SVPWM is applied to the wind energy system to control the operation of the wind turbine-driven, delivering high-quality voltage output with reduced harmonic distortion. The integration of these control techniques is facilitated through a centralized hybrid energy management system, enabling seamless energy distribution, synchronization, and grid connectivity. Simulation results demonstrate the effectiveness of the proposed strategy in maintaining power balance, reducing total harmonic distortion (THD), and ensuring reliable operation under dynamic load and environmental conditions. This work underscores the potential of advanced PWM techniques in advancing hybrid renewable energy systems toward greater efficiency and sustainability.
