Abstract

Inter-Area power oscillation damping is of fundamental importance in today's era of sophisticated and highly complex power system. The present paper demonstrates a practical solution obtaining satisfactory performance in damping power system oscillations utilizing the flexible Voltage Source Converter-High Voltage Direct Current (HVDC-VSC) transmission technology in an optimal combination with a Power Oscillation Damping (POD) controller such as Nonlinear Autoregressive Moving Average (NARMA-L2), utilizing active power modulation technique. The primary focus of the control scheme is to improve the damping of lightly damped or even unstable modes of the interconnected AC/DC power system through modal identification and estimation techniques. The performance of aforesaid control technique is compared with that of conventionally tuned PI control scheme. The designed control scheme guarantees stability margins through eigenvalue analysis and non-linear time domain simulations during symmetrical and asymmetrical faults. The software platform under which the various simulation scenarios were implemented is MATLAB/Simulink.
