To mitigate the frequently over-threshold subsynchronous oscillation (FOSSO) phenomenon which occurred in Hulunbuir power plant in the northeast of China, a novel equipment based on voltage source converter (VSC), named subsynchronous oscillation dynamic suppressor (SSODS) is developed and installed. In this study, the root cause of FOSSO is revealed by analysing the response characteristics of the system. Then the control strategy of the developed SSODS is presented. Damping characteristics of SSODS are analysed by the complex torque coefficient method. To verify the effectiveness of the control strategy and the physical controller of VSC, as well as provide initially optimised controller parameters for the field tests, real-time closed-loop tests are carried out. A novel method of torsional modal frequency measure for onsite commissioning test is proposed. The operation and field verification test of SSODS is introduced, and test results demonstrate that SSODS can mitigate the new SSO phenomenon dramatically, proving the validity of SSODS.

The paper highlights the potential use of wind energy conversion systems for the mitigation of Subsynchronous Resonance (SSR) and Subsynchronous Interaction (SSI). SSR and SSI damping is attained by introducing supplemental control signals in the reactive power control loops of the grid side converters of Full-Frequency Converter (FFC) and Doubly-Fed Induction Generator (DFIG) wind turbines. The effectiveness of the supplemental control in mitigating the two phenomena is demonstrated on a test benchmark through time domain simulation studies using EMTP-RV. IndexTerms -Series capacitive compensation, subsynchronous interaction, subsynchronous resonance, wind energy.

“…However, when the power system is large, the capacity of ESSs will increase dramatically, so the cost of pure active power-based methods is very high. To overcome the cost issue, distributed generation, such as wind power and photovoltaic power, were utilized to suppress the power oscillations in [7][8][9], however, distributed generation has great volatility and randomness, and works in the maximum power tracking mode, so it is difficult to effectively suppress the electromechanical oscillation. Compared with pure active power-based methods, the pure reactive power-based scheme shows great cost advantages.…”

Through the feedback of the rotor speed and/or the grid frequency, an energy storage system (ESS) can effectively suppress the electromechanical oscillation of a power system. This paper proposes a novel control strategy and controller parameter design method for ESSs to achieve the desired performance of oscillation suppression, including smaller frequency and rate of change of frequency (ROCOF) deviation than their threshold values. Firstly, a dynamic model of the electromechanical time scale of a synchronous generator dominated power system with ESS was established. Then, based on the dynamic model and the electric torque analysis method, the mechanism of an ESS with the feedback signal of the rotor speed to suppress the electromechanical oscillation was investigated. Finally, the controller parameter design method for the ESS was developed to achieve the desired performance of oscillation suppression. With the help of the well-designed ESS, the electromechanical oscillation of a synchronous generator dominated power system can be effectively suppressed in shorter transient response times, and the grid frequency deviation and the ROCOF can be limited to below their threshold values. The simulation results also verify the effectiveness of the proposed control strategy and the controller parameter design method.
