Abstract

Grid-forming (GFM) controlled wind power plants (WPPs) has emerged as a promising solution to facilitate the stable integration of renewable energy into power grids. GFM-WPPs operate as voltage sources, capable of responding promptly to voltage disturbances. However, it remains uncertain whether their reactive current profiles (RCPs) conform to the present grid codes. This paper analyses the RCP of an aggregated GFM-WPP system. It offers transmission system operators a reference for grid codes compliance. It is found that the reactive current is naturally provided in proportion to voltage sag depth when inverter current is not limited, adhering to grid codes. However, when the current is limited during faults, the RCP is mainly affected by the active power rather than reactive power setpoints. By using the conventional fault ride-through setpoints of active power, the GFM-RCP can cover the grid code requirements. The profiles are validated by the electromagnetic transient simulations.
