“…In the DPC concept, the voltage magnitude and angle of the converter are controlled directly. By eliminating the current control in the DLC and replacing the rotor speed control in the MSC with a stator active power control based on the look-up table, the classical DLC can be transformed into DPC [48]. DPC reduces the DFIG's equivalent resistance, which results in less negative damping in the subsynchronous frequency (SSF) range.…”

“…DPC reduces the DFIG's equivalent resistance, which results in less negative damping in the subsynchronous frequency (SSF) range. Consequently, under identical operating conditions, the DPC has a superior performance in mitigating DFIG-SSR than the DLC [48]. The investigation was performed using a single-machine infinite-bus system and despite the promising results, further detailed investigation is needed to analyze the stability of the grid forming control in larger-scale power systems.…”

Critical Review of Mitigation Solutions for SSO in Modern Transmission Grids

The replacement of conventional generation by power electronics-based generation changes the dynamic characteristics of the power system. This results in, among other things, the increased susceptibility to subsynchronous oscillations (SSO). First, this paper discusses three recently emerging SSO phenomena, which arise due to the interactions between (1) a doubly-fed induction generator and a series compensated transmission system; (2) a voltage source converter (VSC) and a weak grid; and (3) nearby VSCs. A fundamental review of these phenomena resulted in the requirement for a reclassification of the existing SSO phenomena. This reclassification is proposed in this work and is based on interacting components identified using participation factor analysis for the distinct phenomena. Second, a critical review of the existing mitigation measures is performed for these phenomena, highlighting the advantages and disadvantages of the solutions. The influence of the wind speed, grid strength, number of wind turbines, and several converter controller parameters are also discussed. To assist equipment manufacturers, control design engineers, and system operators in selecting and designing effective mitigation measures, the existing solutions are categorized in control solutions, hardware solutions, and solutions based on system level coordination. Finally, perspectives on open issues conclude this paper.

This paper assesses the suitability of the phase imbalance concept as an alternative approach for series compensating a transmission line, with the goal to eliminate adverse subsynchronous interactions between a DFIG and the transmission system. The performance of this concept, under a predefined degree of asymmetry, is compared with the classical series compensation scheme. First, it is concluded that the phase imbalance concept can reduce subsynchronous oscillations, as this concept results in lower resonance frequencies, which in turn lead to increased damping. Second, as these resonance frequencies remain in the DFIG's negative resistance region, the subsynchronous oscillations cannot be fully mitigated.

“…What is more, for damping controller's location, its input control signal and parameter setting, the existing practices are generally time consuming and lack of a definite quantitative index. In [16], three types of RSC with different input signals are compared with respect to the SSCI performance, based on impedance methods. The best of three turns out to be the final choice of input signals.…”

“…the power system stabiliser (PSS) supplemented to the DFIG converter (DFIG‐PSS) is designed in probabilistic environment to achieve the purpose of suppressing SSCI at different operating points of the system. What is different with the existing published methods is that quantitative indices are used as a reference in this paper to make the design process more efficient and directed [6, 16]. Probabilistic sensitivity index (PSI) is utilised to select the site and the input control signal as well as to optimise PSS parameters for better probabilistic sub‐synchronous stability.…”

This paper presents a probabilistic design of a power system stabilizer (PSS) for doubly-fed induction generator (DFIG) converter and investigates its potential capability in mitigating the sub-synchronous control interaction (SSCI) under multi-operating points of. The aim is to improve the probabilistic sub-synchronous stability of the system with wind farm penetration. In this paper, Participation Factors (PFs) are obtained to identify the SSCI strong-related state variables and major control loops, which are used for the preliminary siting of the DFIG-PSS. Probabilistic sensitivity indices (PSIs) are then employed for accurate positioning of the PSS, selecting the input control signal and optimizing the PSS parameters. The effectiveness of the proposed approach is verified on a modified two-area power system.
