The preeminence of wind power as a source of clean power generation is growing very fast. The increasing wind penetration, however, escalates the problem of low‐frequency oscillations (LFOs) in the modern grid. In this paper, LFOs damping improvement is presented for a high wind penetration power system by a robust coordinated control strategy of the power system stabilizer (PSS) and power oscillation damper (POD) of doubly fed induction generator (DFIG). This control strategy is achieved using an improved eigenvalue‐based objective function, optimized using grey wolf optimizer (GWO). The impact of wind farm location on system oscillatory stability is accomplished using eigenvalue analysis and dynamic sensitivity analysis. The wide‐area‐based phasor measurement unit (PMU) signals are used as PODs input selected using modal observability criterion. The eigenvalue analysis, time‐domain simulations, and robustness analysis are performed to verify the efficacy of the proposed control strategy on a modified IEEE New England test system. The simulation results show the improvement in LFO damping with the proposed control strategy for a wide range of operating scenarios including faults and line outages at different loading conditions.

“…The simultaneous coordinated control of DFIGs with wide‐area‐based controllers is obtained in previous studies . Zhang et al, coordinately control the PODs and PSSs along with optimally controlling plant dynamics. As local signals lack global modes observability, proper selection of input signals is also an important criterion …”

“…The measurement sampling and the control signal update are performed at a rate of 25 Hz, and a time delay of 200 ms is considered for both measurement and control communication channels; therefore, time-delay models with N = M = 5 are implemented. This approach in the discrete-time domain is able to represent communication time delays more accurately than other approaches in the continuous-time domain based on Padé approximations [40]- [42].…”

This work presents a hierarchical control strategy to improve the stability of electrical networks with significant converter-interfaced generation (CIG). Due to the lack of inertia of CIG systems, these networks can undergo a high rate of change of frequency, compromising the frequency stability. In a first level control, a local controller based on the virtual synchronous generator (VSG) concept is used to emulate inertia and provide short-term frequency regulation. However, the inclusion of significant VSG units can have a negative impact on the damping of inter-area oscillations. Therefore, in a second level control, a centralized controller is proposed to damp these low-frequency electromechanical oscillations affected by VSGs. Several practical issues such as the identification of a system model for the control design, the compensation of communication delays, and the discrete-time implementation of the controller are particularly analyzed. The introduced supplementary controls allow increasing the penetration of renewable energy sources without jeopardizing the frequency and small-signal stability. Eigenvalue analysis and nonlinear hybrid simulations combining DIgSILENT and Python are performed to validate the proposed control strategy.

“…For interval oscillation, the best wide-area signal is the rotor angle difference [21,22]. In order to determine the controllability and observability of the interval oscillation mode, the optimal installation position of the damping controller using the residue method are the generator 4 and the wind farm [23].…”

A Coordinated Dual-Channel Wide Area Damping Control Strategy for a Doubly-Fed Induction Generator Used for Suppressing Inter-Area Oscillation

et al. 2019

Using a doubly-fed induction generator (DFIG), with an additional active or reactive damping controller, is a new method of suppressing the inter-area oscillation of a power system. However, using active power modulation (APM) may decrease the damping of the shaft oscillation mode of a DFIG and the system damping target cannot be achieved through reactive power modulation (RPM) in some cases. Either single APM or RPM does not consider system damping and torsional damping simultaneously. In this paper, an active-reactive coordinated dual-channel power modulation (DCPM) damping controller is proposed for DFIGs. First, considering the electromechanical parts and control structure of the wind turbine, an electromechanical transient model and an additional damping controller model of DFIGs are established. Then, the dynamic objective function for coordinating the parameters of the additional damping controller is proposed. The ratio between the active power channel and reactive power channel modulation is derived from the parameters optimized by the particle swarm optimization algorithm. Finally, the effectiveness and practicability of the designed strategy is verified by comparing it with a traditional, simple damping controller design strategy. Standard simulation system examples are used in the comparison. Results show that the DCPM is better at maximizing the damping control capability of the rotor-side controller of a DFIG and simultaneously minimizing adverse effects on torsional damping than the traditional strategy.
