“…Many methods have been proposed for design of PODC, such as the residue method [4], optimal pole shifting (OPS) technique [5] and so on. However, because of the diversity of the real-time operating conditions of power system, solely application of these methods cannot provide satisfactory damping to every operating condition, which may threaten the safety and stability of power system.…”

SUMMARYDue to the diversity of operating conditions of real-time power system, traditional power oscillation damping controller (PODC) of static synchronous compensator (STATCOM), which only considers single operating condition, could not provide sufficient damping when operating condition changes. To solve this problem, this paper proposes a robust design method for PODC. The total least squares-estimation of signal parameters via rotational invariance techniques (TLS-ESPRIT), which performs well in term of anti-noise and accuracy, is suggested to identify the transfer function and residues of the system. The residue-based approach considers several typical operating conditions so that the designed PODC could adapt to multiple operating conditions. The simulation result demonstrates that, compared with the traditional method, PODC of STATCOM designed by the proposed method damps the low-frequency oscillation more effectively and is more adaptable to the change of operating conditions.

Flexible alternating current transmission systems (FACTS) are gaining more attention in power utilities because of their advantages of controllability, reliability, and operation over a wide range. Static synchronous compensator (STATCOM) and static series synchronous compensator (SSSC) are prominent FACTS topologies; they have the ability to instantaneously regulate active/reactive powers and stabilize the power system following severe disturbances. In this paper, STATCOM and SSSC are compared with regard to their damping action on power system oscillations. The comparison is extended to the controller design strategies. Two distinct meta-heuristic optimization approaches, namely chaos (CO) and simulated annealing (SA), are recommended for the optimal design of the SSSC and STATCOM damping controller. To assess the promising FACTS topology, a single-machine infinite bus system is subjected to several disturbances while operating at different loading levels. MATLAB/Simulink is used as a platform to investigate the dynamic performance of the system under consideration with STATCOM and SSSC. Simulation results reveal the superiority of SSSC in damping power system oscillations in terms of response speed and stability margin. Moreover, the CO optimization scheme seems to outperform the SA algorithm in terms of computation requirements and global optimal convergence.
