(2018). Decentralized Control of Offshore Wind Farms Connected to Diode-Based HVdc Links. IEEE Transactions on Energy Conversion, 33(3), pp. 1233–1241.0885-8969https://hdl.handle.net/10016/32614This paper presents a novel decentralized control for offshore wind farms connected to the onshore grid through a high-voltage dc link by means of a diode rectifier. The proposed control system is implemented in each wind turbine generator system (WTGS). The capacitor placed at the filter of the wind turbine front-end converter is used for the proposed control implementation. Frequency control is achieved by aligning the capacitor voltage vector along a reference axis rotating at the reference frequency. Then, a frequency-reactive power droop control allows the synchronization of all the WTGSs. On the other hand, this droop strategy also leads to total reactive power sharing among WTGSs without relying on communications. An additional secondary frequency control is also implemented to compensate the frequency deviation caused by the droop control. The proposed control system has been validated by simulation and results demonstrate the appropriate performance even during start-up and faults.9eng© 2018, IEEEDiode rectifierOffshore wind farm (OWF)Frequency controlDistributed controlHigh voltage dc (HVdc) transmissionresearch articleElectrónicahttps://doi.org/10.1109/TEC.2018.2804662open access123331241IEEE Transactions on Energy Conversion33AR/0000021985
