Abstract This paper presents methods to model and solve high‐frequency resonance problems in HVDC and wind power systems. Control and digital PWM delays are identified as a common root cause for such resonances. A systematic method to include such

Small-signal sequence impedance models have been developed for different types of wind turbines and used in industry to study wind farm and high-voltage direct current (HVDC) system harmonics and resonances. Compared to other small-signal methods, a

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

Delay is inevitable in power converters employing digital control and/or digital pulse-width modulation (PWM), and can be modeled in different forms for different purposes. This paper presents the modeling of such delay in frequency domain by small-s

This paper first presents the phenomena of the offshore wind farm (OWF) experience following the blocking of the high voltage direct current converter used for connecting the wind farm (WF) to the main onshore grid. Measurements in real large WFs sho

This paper presents measurement and simulation results in offshore wind farms following blocking of the HVDC converter used for connecting the wind farm to the main onshore grid. It is shown that the voltage will rise by approximately 30% within 50

Wind turbine controllers are generally designed for grid connected operation. Under certain grid conditions such as islanding of offshore wind farms following HVDC converter blocking, voltage and frequency of the island remains uncontrolled. Measurem
