“…To mitigate the over-/under-voltage, the dc-link voltage control and ac current control are commonly adopted in AFE [12], [13], [53]. Due to the limitation of the AFE control bandwidth, the settling time of dc-link voltage in grid emulators generally ranges from 20 ms to hundreds of milliseconds [13], [53]. By increasing the control bandwidth of AFE control for a settling time of 20~100 ms, it is possible to reproduce 6 consecutive faults, due to the fact that the time duration of a single fault is larger than 100 ms and the recurring time of each fault is greater than 300 ms [29].…”

“…Additionally, the -R also appears within [1/(4Td), fs/2] for the voltage-magnitude emulation by the dual-loop voltage control [60] and the impedance emulation [63]. Thus, reducing time delay is a direct method to mitigate -R. centralized control and the distributed control [12], [49], [53], [54].

Power-electronic-based grid emulators are emerging as a promising way to test the grid-code compliance of renewable energy resources. Yet, the ever-increasing power and voltage levels of device under test pose new requirements and challenges to power-electronic-based grid emulators. This paper first gives an overview of testing capability requirements based on the recent grid codes and standards, then discusses the resulted dynamic interactions and solutions for power-electronic-based grid emulators. Perspectives on the open issues and emerging trends of grid emulators are finally shared.

Wind turbines are a driving force in the change towards renewable energies today. Offshore wind turbines have reached power ratings around 15 MW, and the growth continues. Grid emulators have become inevitable for the test and validation of wind turbines and subsystems at full scale. Yet, large investments for new installations present major challenges.Therefore, the following discussion outlines basic design aspects for the grid emulator main components: converter, transformer, and filter. The aim is to clarify the implications of requirements on the design to exhaust ratings for minimum investments, and to satisfy testing against the most recent standards and grid codes. Appropriate ratings are derived based on steady-state and transient test needs. It is shown how much overrating is specifically needed and why the converter is usually rated a multiple compared to the device under test. Further dimensioning criteria such as power quality, switching frequency, and filter size are discussed in this context.Finally, the capacity of grid emulators is often characterized by the short-circuit power. Two essentially different variants of short-circuit power are introduced, either being dependent on the converter peak current or the passive components impedance. While the first one reveals the overload capability, the latter represents a proper measure for grid strength. However, the emulated grid strength can be adjusted in a limited bandwidth using impedance control. The concept might be confusing at first glance, but it effectively decouples the virtual short-circuit power from the ratings of the power hardware.
