“…According to the results in TABLE IV -TABLE VI, the grid nodes AC3 and AC4 have the dominating PFs for the around 7 Hz dynamic mode and the grid nodes AC7 and AC8 have the dominating PFs for the around 18 Hz dynamic mode in most grid conditions as shown in Figure 1, Figure 5 and Figure 8, thus an oscillation mitigation scheme might be preferably configured at these grid nodes [9]. A very effective way is to add active damping control in the HVDC converters at AC3 and AC7, so that no additional passive or active damping devices should be installed there [7], [20]. Moreover, proper damping design in HVDC converters can de-risk the potential oscillation stability for a wide frequency range until the limits of their PWM modulation capability are reached [8], [32], [33].…”

“…This issue was properly treated in the Ybus based method, which uses nodal admittance matrix for stability assessment [19]. But Ybus based method is typically applied to single sequence component system, which neglects the coupling between positive-and negativesequence impedances [20]. Moreover, the integration of AC-DC dynamic coupling into Ybus based method has not been found in literatures so far.…”

In recent years, the wind energy conversion system faces significant challenges for stable and secure operations, especially in the weak grid due to high penetration of wind energy into the grid. Doubly fed induction generator (DFIG) is one of the most popular wind turbine generators due to its cost‐effective variable speed and low‐cost partial size power converter. Impedance interaction between series or parallel compensated weak grid and the DFIG system causes sub‐synchronous resonance (SSR) and high‐frequency resonance (HFR). A comprehensive review of the state‐of‐the‐art SSR and HFR in the DFIG system under a weak grid is presented. First, based on features, such as supplementary hardware, linear and non‐linear control strategies, the resonance damping techniques are classified into different types. Then, the advantages and disadvantages of SSR analysis and damping techniques techniques are put forward. Moreover, the latest development of state‐of‐the‐art SSR and HFR analysis and damping techniques are supplemented. Finally, the contemporary and future trends of the SSR and HFR techniques are discussed.

“…This problem increases with the rise in the stochasticity of the wind speed, and, hence, it becomes difficult to control and stabilize the voltage and frequency of hybrid HVDC systems using conventional controllers. Various techniques have been proposed for improving the stability of the frequency and the voltage of hybrid HVDC systems [29][30][31][32]. However, the dynamic and stochastic behavior of the HVDC system increases the scope of research in this field.…”

Lack of synchronization between high voltage DC systems linking offshore wind farms and the onshore grid is a natural consequence owing to the stochastic nature of wind energy. The poor synchronization results in increased system disturbances, grid contingencies, power loss, and frequency instability. Emphasizing frequency stability analysis, this research investigates a dynamic coordination control technique for a Double Fed Induction Generator (DFIG) consisting of OWFs integrated with a hybrid multi-terminal HVDC (MTDC) system. Line commutated converters (LCC) and voltage source converters (VSC) are used in the suggested control method in order to ensure frequency stability. The adaptive neuro-fuzzy inference approach is used to accurately predict wind speed in order to further improve frequency stability. The proposed HVDC system can integrate multiple distributed OWFs with the onshore grid system, and the control strategy is designed based on this concept. In order to ensure the transient stability of the HVDC system, the DFIG-based OWF is regulated by a rotor side controller (RSC) and a grid side controller (GSC) at the grid side using a STATCOM. The devised HVDC (MTDC) is simulated in MATLAB/SIMULINK, and the performance is evaluated in terms of different parameters, such as frequency, wind power, rotor and stator side current, torque, speed, and power. Experimental results are compared to a conventional optimal power flow (OPF) model to validate the performance.
