Modeling the System for Hybrid Renewable Energy Using Highly Efficient Converters and Generator

High-efficient isolated DC/DC converters with a high-efficiency synchronous reluctance generator (SRG) are the ultimate solutions in DC microgrid systems. The design and modeling of isolated DC/DC converters with the performance of SRG are carried out. On the generator side, reactive and active powers are used as pulse width modulation (PWM) control variables. Further, the flux estimator is used. Three-phase PWM rectifier is used by applying space vector modulation (SVM) with a constant switching frequency for direct power control. Further, the paper also includes the experimental validation of the results. The paper also proposes that highly efficient power converters and synchronous reluctance generators are required to achieve high performance for hybrid renewable energy systems applications.
