Abstract
Virtual synchronous machine (VSM) control has been put up and developing for the past ten years, but not much work has been done specially focusing on its application on wind turbines (WTs). This paper gives a thorough review of the work that has been done until now about application of VSM control on WTs. Aspects on control schemes, energy storage (ES), frequency and voltage control capabilities, different grid conditions etc. are summarized separately. Further research work in this field is emphasized.
Highlights
With more and more renewable power like solar power and wind power being integrated to the traditional power system, the total inertia of the power system is getting lower and lower
When a wind turbines (WTs) with Virtual synchronous machine (VSM) control was connected to a strong AC power grid, its steady state performance was compared to an adjacent WT operating with classical current control
For weak power grid integration, RTDS simulations show that VSM control can operate in power grids of lower SCR compared to conventional current control
Summary
With more and more renewable power like solar power and wind power being integrated to the traditional power system, the total inertia of the power system is getting lower and lower. This paper gives a thorough review of the work that has been done until now about application of VSM control on WTs. Aspects on control schemes, energy storage (ES), frequency and voltage control capabilities, different grid conditions etc. Different VSM control schemes were reviewed and categorized in [3] based on the nature of the output reference from SG model: current reference, voltage reference and power reference.
