“…The major challenge of selecting a speed deviation as an Input Control Signal (ICS) is to capture the angular speed deviation of a generator and transmit it to the other components of the system that are far away from the generator. The advance in technologies such as WAMS, PMU, and communication networks allows obtaining the most accurate and real-time data on the dynamic parameters of a complex power system [42,43]. At the same time, it is essential to have real-time data for the parameters such as frequency, voltage, and current from the generating station to the transmission system.…”

This paper presents the issue of the Sub-synchronous resonance (SSR) phenomenon in a series compensated DFIG-based wind power plant and its alleviation using a Battery Energy Storage-based Damping Controller (BESSDCL). A supplementary damping signal is developed considering the angular speed deviation and is incorporated into the BESS control system. Wide-area Measurement System data is used to determine the angular speed deviation. A linearized system model is developed to perform eigenvalue analysis, and to detect and examine unstable SSR modes. The variation of wind speed and three-phase fault are also taken into consideration to validate the robustness of the controller. To further verify the efficacy of the proposed damping controller, time-domain simulations are performed using MATLAB/Simulink. The application of the proposed BESSDCL stabilizes all the unstable system modes effectively at wind speeds of 7 m/s, 9 m/s, and 11 m/s, and at 40%, 50%, and 60% series compensation levels, as well three-phase fault conditions.

“…In recent years, the increasing penetration of wind generation has raised the risk of subsynchronous oscillation (SSO) [1][2][3][4][5][6]. In real-life wind farms, SSO has been observed in many places around the world, such as the electric reliability council of Texas (ERCOT), USA and Hami, China [7][8][9][10][11]. Once SSO occurs, power systems will suffer from severe damage and huge economic losses.…”

The subsynchronous damping controller (SSDC) has been widely recognized for its excellent performance and low cost in subsynchronous oscillation (SSO) mitigation for the doubly fed induction generator (DFIG)-based wind power system. However, the existing SSDCs are various and lack a systematic comparison. To fill this gap, the structures and parameter design methods of common SSDCs are sorted and compared in this paper. It is found that the rotor-current-based method performs best in terms of dynamic performance and robustness, as it can mitigate SSO for all working conditions in the test, while the feasibility range of other methods is much smaller. Therefore, the influence of different parameters in a rotor-current-based SSDC on SSO mitigation is further researched, leading to a guideline for parameter selection. More importantly, to address the challenge of time-varying oscillation frequency, an adaptive frequency selection method is proposed based on the eigensystem realization algorithm, which can accurately track the SSO frequency within 5~45 Hz. The results of the root locus analysis and hardware-in-the-loop experiment demonstrate that the improved rotor-current-based SSDC performs better than other existing methods, and it does not affect the normal operation of the DFIG.

“…For example, on 15 September, 2011, PHESs were stopped because of the depletion of water in the upper reservoir, which resulted in cascading load shedding (i.e., a rolling blackout) in Korea [12,13]. This was due to the faster increase in temperature-sensitive loads than the response of reserve resources.…”

Abstract:The high penetration of renewable energy resources has made it harder to secure a flexible power system. Accordingly, this has become an issue in operating power systems. As a possible solution, pumped hydroelectric energy storage (PHES) has received much attention because of its fast start-up and ramp characteristics. This study proposes a flexibility-based reserve scheduling method for PHES. In this method, the reserve scheduling of PHES was conducted to improve flexibility; the associated risk index was termed the ramping capability shortage expectation (RSE). The peak-load days in 2016 and 2029 were selected to examine the applicability and performance of the proposed method. Results indicate that the proposed method can improve the flexibility by 4.45% for 2016 and 0.9% for 2029, respectively.
