“…at means the optimization needs to take into both the phasefrequency and the amplitude-frequency properties. In equation (4), the constraining conditions are the requested items defined by the standard [20]. ese constrain conditions are set to ensure the positive direction of the vector M. By keeping the vector M in the positive direction, the angle error of the moment T t can be avoided so that the damping effect can be kept on a satisfied level.…”

In this paper, we proposed the comprehensive damping effect method to optimize the PSS parameters. Different from other studies, the optimization in this paper is based on both the amplitude-frequency and the phase-frequency properties, while other studies mainly focus on the phase-frequency characteristics. The actual grid data in Northern China are employed to verify the optimization effect in the multimachine system. The proposed method is compared with the engineering method, the existing optimization method, and the commercial software. The comparison shows that the PSS parameters obtained by the proposed method in this paper are superior to those obtained by the engineering experience, the phase-frequency optimization method, and the commercial software. In the cases of different phase-frequency range requirements, the wider the phase-frequency range is, the better the damping effect of the obtained parameters will be.

“…To improve system's damping, different kinds of power system stabilizers (PSSs) are designed, such as multi-objective PSS [4], wavelet-based PSS [5] and distributed PSS [6]. In principle, the PSSs inject an additional damping signal to enhance the oscillation damping performance by controlling the excitation voltage of the synchronous generator (SG).…”

Static synchronous compensator (STATCOM) and battery energy storage (BES) have been increasingly employed in power systems for the reliable and economic operation of power transmission. However, the transient interaction between the electrical power of synchronous generator (SG) and the active power of STATCOM with/without BES is still misunderstood and treated incorrectly. This paper presents an analysis of this interaction and investigates the control and optimal placement of STATCOM with/without BES for the purpose of improving SG’s damping, and thus enhancing system’s oscillation damping performance. The results show that (1) the deviated electrical power of SG is not equal to the active power of STATCOM. Instead, it is related to STATCOM’s current, placement and SG’s electrical states, (2) with the increased damping as the index, the optimal location for STATCOM with BES is at the terminal of SG, while it is at the electrical mid-point of the transmission line for STATCOM without BES. Non-linear simulations and eigenvalue analysis are performed to validate the correctness of the above results.
