Abstract

This paper presents the establishment of a novel linearised Phillips-Heffron model of a power system installed HVAC parallel-connected with a Back To Back High Voltage Direct Current based voltage source converter (BtB VSC HVDC). In addition, a supplementary controller for a BtB VSC HVDC to damp low frequency oscillations in a weakly connected system is proposed. The potential of the BtB VSC HVDC supplementary controllers to enhance the dynamic stability is evaluated by measuring the electromechanical controllability through singular value decomposition (SVD) analysis. The presented control scheme not only performs damping oscillations but also the voltage and power flow control can be achieved. Simulation results carried by MATLAB show the effectiveness of proposed strategy for enhancing dynamic stability.
