Abstract (englisch):

Due to the increasing share of converter-interfaced generation in power systems, system inertia decreases and system stability is endangered. It has been shown in recent years that the use of grid-forming control methods for converter-interfaced generation systems can contribute to system inertia and could thus ensure system stability at very high share of converter-interfaced generation. Due to the limited overcurrent capability of converters in the event of grid faults, the implementation of safe and reliable overcurrent limitation is mandatory in real converter applications. This paper presents an enhanced Synchronverter-based grid-forming control method with current limiting capability for three-phase grid-side converters of type 4 wind power plants. In order to investigate the feasibility of the proposed control method on hardware as used in state-of-the-art wind power plants, the control method is implemented on a test converter, which realistically represents the converter of a 60 kVA laboratory scale wind power plant. Measurement results of the operation of the Synchronverter and its current limitation under grid disturbances are presented in the paper, demonstrating the applicability of the control method to wind power plants.
