Implication
Experimental study demonstrates suppression of resonance and oscillations in parallel grid-connected converters, suggesting improved power system stability.
Key Points
- To develop an active damper based on a high-bandwidth power electronics converter that stabilizes parallel grid-connected converters by dynamically reshaping grid impedance.
- Designed an active damper to dynamically modify the grid impedance profile observed from the point of common coupling of parallel converters.
- Evaluated the damping performance using both computer simulations and experimental testing on a three-converter hardware platform.
- Mitigated potential electrical oscillations and resonance propagation across the parallel grid-connected converters.
- Demonstrated qualitative stabilization of the power-electronics-based alternating current power system under coupled grid impedance.
