A Simplified Synchronous Machine Model for Virtual Synchronous Generator Implementation
Résumé
Microgrids which still insure the system’s stability. In this paper an improved synchronous machine model for the VSG-based inverter is proposed. The model represents the dynamics of the synchronous machine and has the advantage to respect the synchronous machine standards. The proposed model is detailed and completed with a frequency-response characteristics study. Two different validations are presented to support this new model. Firstly, a comparison with a previously developed model, implemented in the control of an inverter is presented. Secondly, to validate the fact that the proposed synchronous machine model respects the standards, harmonics studies are performed and discussed.
