High-Precision VSG for Stable Microgrid Synchronization
A Virtual Synchronous Machine for Synchronizing Three Phase Inverters with an Electricity Grid
Tags: IIT Delhi, India, Infrastructure, Utilities & Communications, Energy & Environment
A virtual synchronous generator (VSG) has been developed to enhance the synchronization of three-phase inverters in microgrids using a switching-vector-based control approach. It consists of a DC power source, voltage source converter, reference voltage generator module, switching-vector controller, and filters, ensuring optimal inverter switching sequences. The system eliminates the need for traditional PI regulators, improving power quality while ensuring zero frequency deviation from the grid. It also provides over-current protection, harmonic mitigation, and IEEE 519 compliance. Applications include energy management and microgrid synchronization for stable and efficient power distribution.
