Real-time Simulation Framework for Validating Controllers of Virtual Synchronous Generators

The utilization of active rectifiers as converters in the interface between AC and DC microgrids has become a prevalent practice owing to their capacity to facilitate bidirectional power flow. The contemporary methodology for the development of power converters includes the integration of real-time simulation steps for the validation of control schemes and the assurance of safe implementation with hardware. The present study pro-poses a methodology for developing a real-time Hardware-in-the-Loop (HIL) simulation framework, which aims to facilitate the rapid prototyping of advanced control algorithms for an Active-Front-End (AFE) rectifier, especially a Virtual Synchronous Generator (VSG) control strategy. This approach aims to enhance the dynamic performance and stability of low-inertia power systems by mimicking the behavior of a synchronous generator, thereby providing virtual inertia to the power system. The control schemes and the primary circuit models are designed and implemented uti-lizing Matlab/Simulink and are optimized for code generation. © 2023, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).
