“…In this case, the triggering condition was similar to the one experienced in Texas, i.e., after a fault on the system the wind farm became radially connected with a corridor with 60% of series compensation [22]. Another incident was reported in the north of China, where a 3000 MVA wind generation (composed mostly of DFIG turbines) experienced very low-frequency oscillations [23,24]. The problem was associated to SSI and in this case, the oscillations vanished after the successive disconnection of generation units.…”

“…Notice that when 94.8% [bifurcation G(ī r ) in Fig. 5(c)], the cycle grazes the boundary 24 and t 2 = t 3 . On the other hand at the non-smooth saddle-node point NSN( i r ) for 90%, the cycle grazes the boundary 12 and t 1 = t 4 .…”

“…In fact, the electromagnetic oscillation is one of the typical problems in power electronized power systems [1,2]. In the point view of oscillation frequency, the oscillation phenomenon in CTAIP is similar to the oscillation caused by subsynchronous control interaction (SSCI) [3,4]. There has been a large number of studies focused on SSCI.…”

The central Tibet AC interconnection project (CTAIP), which connects the Tibet power grid and the Sichuan power grid through a long distance transmission line of more than 1400 km, has a significant problem of voltage regulation. In order to improve the voltage regulation performance, six sets of ±60 Mvar static VAR compensators (SVC) were installed in the CTAIP. However, the SVCs may lead to electromagnetic oscillation below 50 Hz while improving voltage regulation capability. In this paper, the electromagnetic oscillation modes and the sensitivity of control parameters of SVC are analyzed. Then, the characteristics and influencing factors of the oscillation are discussed. It was found that there is an inherent electromagnetic oscillation mode below 50 Hz in the ultra-long distance transmission system. The employ of SVCs weaken the damping of this mode. Large proportional gain and integral gain (PI) parameters of SVCs can improve the voltage regulation performance, but weaken the electromagnetic oscillation mode damping. Therefore, a suppression method based on SVC PI parameters optimization is proposed to damp the oscillation. The essential of this method is to use the rising time of voltage response and setting time of SVCs as performance indicators of voltage regulation, and take the damping level of the electromagnetic oscillation mode as the performance index of SVC electromagnetic oscillation suppression ability. Combining the two indicators to form a comprehensive optimization index function, an intelligent optimization algorithm is applied. The process of SVC parameter optimization and the steps of multi-SVC parameter optimization in large power grids is proposed. Finally, PSCAD and real-time digital simulation (RTDS) simulation results verified the correctness of the proposed method. The optimization strategy was applied to CTAIP. The artificial grounding short circuit experimental results proved the effectiveness of the proposed strategy.
