“…In this paper, the academic terminology ''oscillatory stability'' is adopted. The eigenvalue-based analysis is a fundamental and conventional method for the power system stability analysis, which is available for both model-based and measurement-based assessment of the oscillatory stability in the power grid [44], [45]. The damping essentially characterizes the decaying rate of the oscillation, which is related to the real part of the eigenvalue [46].…”

With increasing power electronics integrated into the power grids, the new types of oscillation issues have posed a critical threat to the secure operation of power grids. Apart from the conventional eigenvalue-based analysis, the impedance-based analysis becomes more attractive for the assessment of the oscillatory stability. This paper presents a systematic survey on the technical matters of the emerging impedance-based oscillatory stability analysis of power systems with high power electronics penetration. Firstly, the detailed derivation of impedance models of the power electronic converter-connected equipment are discussed. Then, common coordinate systems for the derivation of impedance models, as well as the characteristics of the impedance model in different coordinate systems are surveyed. On this basis, the aggregation of the individual impedance models is introduced to derive the lumped impedance model. Additionally, two typical impedance-based oscillatory stability criteria are demonstrated and discussed in details. Finally, the advantages as well as the limitations of the impedance-based oscillatory stability analysis, and the contributions as well as the challenges of the existing studies are summarized. A list of relevant literature is accommodated in the end.

“…In addition, packet loss also affects the quality of the data acquired by the synchrophasor network. Research studies have estimated the impact of latency and packet loss in synchrophasor data streams and developed strategies to deal with these issues [21]- [24]. In addition to the communication protocol related issues, synchrophasor measurements are also affected by the noise and bias errors, hence synchrophasor measurement devices must be calibrated to ensure the fidelity of the phasor measurement.…”

Oscillatory stability has received immense attention in recent years due to the significant increase of power-electronic converter (PEC)-interfaced renewable energy sources. Synchrophasor technology offers superior capability to measure and monitor power systems in real time, and power system operators require better understanding of how it can be used to effectively analyze and control oscillations. This paper reviews stateof-the-art oscillatory stability monitoring, analysis, and control techniques reported in the published literature based on synchrophasor technology. An updated classification is presented for power system oscillations with a special emphasis on oscillations induced from PECinterfaced renewable energy generation. Oscillatory stability analysis techniques based on synchrophasor technology are well established in power system engineering, but further research is required to effectively utilize synchrophasor based oscillatory stability monitoring, analysis and control techniques to characterize and mitigate PEC-induced oscillations. In particular, emerging big-data analytics techniques could be used on synchrophasor data streams to develop oscillatory stability monitoring, analysis and damping techniques.

In order to improve the small-signal stability of AC/DC hybrid systems containing voltagesource converter based high-voltage direct current (VSC-HVDC), this paper extends damping torque analysis (DTA) theory to VSC-HVDC supplementary damping controller to analyze its dynamic impacts and inhibit oscillations. Firstly, this paper presents the mechanism and procedure of VSC supplementary damping controller and establishes the linearized model of AC/DC system with damping controllers. On this basis, the DTA theory of VSC supplementary damping controller and the equation of damping torque index (DTI) are derived. The theory can be applied to the design of the damping controller including the selection of installation location and channel as well as the parameter tuning. Finally, case studies are carried out in two AC/DC hybrid systems containing VSC-HVDC. The simulation results verify the correctness and feasibility of DTI analysis. VSC damping controllers designed by the proposed method can effectively suppress oscillations and improve the dynamic stability of the AC/DC system.
