Abstract

AbstractAn extensive analysis of the effects of High Voltage Direct Current (HVDC) systems on the small-disturbance stability of power systems is presented within this chapter. Initial comparisons are made between different HVDC technologies, assessing the impact of their placement and power transfer on the electromechanical modes within a small test network. Following this, Power Oscillation Damping (POD) controllers are designed and their effects are investigated for a variety of system configurations. This comprehensive analysis of the supplementary POD control includes multi-terminal HVDC studies, demonstrating the effectiveness of HVDC grids for oscillation damping control. For a wide range of operating configurations, the use of wide area signals and a multivariable control structure is shown to outperform traditional POD controller designs.KeywordsActive PowerPower FlowHigh Voltage Direct CurrentModulation CapacityConverter StationThese keywords were added by machine and not by the authors.
