Abstract

This article regards a power system containing multiple High Voltage Direct Current (HVDC) links. The topic is to exploit the HVDC lines´ ability to control the power supplied by them to increase the stability of the system. The nonlinear controller-design method backstepping is applied to design a controller for the direct current (DC) through each HVDC link. The simulation results show that the controller increases both transient stability and damping when some non-permanent errors are imposed on the system.
