Hybrid Impedance Reshaping based Resonance Damping for the Wind Farm Connected HVDC
2020 4th International Conference on HVDC (HVDC), 2020 When the renewable energy system connects to the power electronized voltage source (PVS), such as the voltage controlled energy storage station and HVDC station, the control delay of PVS results in a fact that, the impedance phase of the PVS exceeds 90° periodically with the frequency increasing, while the impedance of renewable energy system side can ...

Virtual Positive-Damping Reshaped Impedance Stability Control Method for the Offshore MVDC System
IEEE Transactions on Power Electronics, 2019 For the offshore MVDC system, the DC-side medium voltage can easily cause high-frequency oscillation and even instability owing to the complex impedance interactions. The virtual-resistance stability control aiming at rectifier station is introduced from low-voltage DC micro-grid application for mitigating its DC-side oscillation without affecting the ...
