Modelling a Grid-Connected Variable Speed Wind Energy Conversion System Using SCIG With a Study of the Factors Affecting its Output Power

Abstract

This paper examines the modelling, simulation, and optimisation of wind turbine electrical systems within the operational and theoretical frameworks of hybrid microgrids. It engages with the mechanisms of wind energy conversion and the relationship between its generation processes and the structural and functional dynamics of the Wind Energy Conversion System (WECS). The detailed analysis presented explores WECS’s core components such as aerodynamic control subsystems, drivetrain configurations, and generator operations, which collectively influence energy conversion efficiency. Using advanced simulations in MATLAB/Simulink, the study evaluates the impact of critical parameters such as wind speed, pitch angle, and rotor blade dimensions, and provides a methodologically robust investigation into their roles in maximising power output. This research further contributes to the understanding of how precise design and operational control strategies support the integration of wind energy within hybrid systems, and aims to offer perspectives on the interdependent factors necessary for advancing resilient and sustainable renewable energy solutions.
