Impedance-ratio-based interaction analyses in terms of stability and performance of DC-DC converters is well established. Similar methods are applied to grid-connected three-phase converters as well, but the multivariable nature of the converters and

Inverter output impedance is an important parameter for assessing the stability of a grid-connected system. However, measuring the inverter output impedance is not straightforward because the impedance is affected by a nonlinear coupling over frequen

Impedance-based analysis plays important role in assessing the stability and dynamics of grid-connected inverters and related systems. Measuring the inverter impedance is, however, not straightforward due to the load effect caused by the power grid.

Online Measurement of Offshore Wind Farm Impedance for Adaptive Control of HVDC Transmission Systems
Publikováno v:
2019 20th Workshop on Control and Modeling for Power Electronics (COMPEL).
This work presents online impedance measurement of offshore wind farm impedance using an MMC-based HVDC converter as an active injection and measurement device. The objective is to identify the wind farm impedance in real time to enable adaptive cont
