“…The Gravelines shaft parameters are not available in public domain, so, a parameter identification procedure is employed with the aim of adequately representing subsynchronous dynamics, i.e. the shaft torsional modes [12]. The mechanical shaft is represented using four connected masses which accounts for the three torsional modes of concern [10].…”

“…Since this type of SSR represents interaction between the control of an HVDC and the mechanical shaft of turbine-generators, it is also commonly referred to as the subsynchronous torsional interactions (SSTI). There have been multiple cases reported on SSTI between LCC HDVC and generators worldwide [9][10] and this topic is well known and well researched [9][11] [12]. However, there is limited practical experience and published work on SSTI with voltage source converter (VSC) based HVDC systems and it is expected that these systems also introduce the risk of SSTI since they typically control active power transfer.…”

This paper presents a comprehensive analytical eigenvalue stability study of subsynchronous torsional interactions between the 1GW Eleclink MMC HVDC and the 1.12GW Gravelines turbine-generator in north France. It shows that when the generator and HVDC have similar power rating and the generator has low frequency torsional mode, the level of adverse interactions can be of significance. The worst case-scenario is when the generator and HVDC deliver rated power from the French to the English grid and the French grid is weak, and in extreme the HVDC could even destabilize the dominant 6.3 Hz mode. The results also show a noticeable effect of PLL, namely, increasing the gains can improve the stability margins. Participation factors are also analyzed for the 6.3 Hz mode indicating that the main cause of the torsional interactions is the HVDC power control loop.The scenario of the HVDC importing power from the English grid shows that the HVDC could deteriorate damping of the 6.3 Hz mode but only for high AC voltage controller gains. Reducing PLL gains in this case improves the damping which also suggests adopting different PLL gains on the rectifier and the inverter. The main findings are verified on the detailed EMTP model.

The Static synchronous compensator (STATCOM) is a renowned FACTS (flexible alternating current transmission system) device used in power grids to cope with protean conditions. This article provides a comprehensive bibliographic review of various aspects of STATCOM developed over the last 16 years. The paper includes a detailed study presenting different models, test systems, and results of various researches. The study covers the modelling, control technology, stability, optimal location, applications, and installation of STATCOM. The modelling of STATCOM is diverse and include various models such as voltage source converters, software-based models, load flow models, pulse width modulation, and modular multilevel converters. The control technology includes a PI/PID controller, fuzzy-based, feedback controller, model predictive controller, sliding mode controller, and miscellaneous controller based on different schemes, algorithms, and controllers. In studying the stability analysis, all stability aspects such as steady-state stability, dynamic stability, and transient stability are considered for the stability analysis. The genetic algorithm, heuristic algorithm, probabilistic technique and branch and bound approach are mainly used for the optimal placement of STATCOM as described in the available research paper. Various applications of STATCOM in power system are identified such as optimal power flow, voltage stability, voltage fluctuation mitigation, fault analysis and total harmonic distortion. This paper, also mentions the current installation of STATCOM is also mentioned with their different locations such as China (2018), and Canada (2019). The current functions of STATCOM still have many limitations. So there is still a lot of room for improvement. This paper will help the researcher finding the reference of a particular topic of interest in different aspects of STATCOM. The finding of different sections of the paper can help the researchers to develop new ideas and work on different prospective of the device.
