摘要：
The grid integration of wind farms by flexible HVDC is an important means to achieve the consumption and transmission of renewable energy. However, the coupling of multi-control loops makes potential instability problems in the system. In order to reveal the interaction between control loops in the system analytically, a single-input and single-output (SISO) transfer function model was developed for permanent magnet synchronization generator (PMSG)-based wind farm interconnected with flexible HVDC system. Based on the SISO model, the influence of wind power fluctuation and AC voltage control (AVC) of flexible HVDC on the stability of interconnected system was studied by using Nyquist criterion and the results show that the interconnected system has the risk of low-frequency oscillation instability while the wind farm output power was transmitted to the rated power. By adjusting the outer loop control parameters of the AVC, the oscillation can be suppressed well. All the results of theoretical analysis are verified by the detailed electromagnetic transient simulation in PSCAD/EMTDC. © 2020 Chin. Soc. for Elec. Eng.
