HESG based WECS Overview, modeling, and fractional order control

In this study, we set out to learn more about how a Hybrid Excited Synchronous Generator (HESG) may operate in a Wind Energy Conversion System (WECS). For use with wind energy, this article presents a solid framework for a HESG coupled to an isolated load. Multiple WECS architectures are discussed before the HESG is suggested as a promising replacement for the standard generator. Then, we modeled wind turbines in Matlab/Simulink, accounting for the aerodynamic component (wind), the electrical component (generator and power converters), and the mechanical component (turbine and drive shaft). To achieve our goals, we presented a control strategy with an inside current loop using a PI corrector and an exterior speed loop using a fractional order PI controller.
