Investigation of poorly-damped conditions in VSC-HVDC systems
Paper i proceeding, 2015

The use of Voltage Source Converter based High Voltage DC (VSC-HVDC) links is regarded as a major step in facilitating long distance power transfer and integrating renewable energy sources, e.g. wind farms. Such systems may experience stability or poor damping related issues and a stability study is considered necessary. The differences in the operating concept between point-to-point connections that either transfer power between existing ac grids or connect a wind farm to the main ac grid, imply a difference in their dynamic behavior as well. This paper examines these two types of two-terminal VSC-HVDC systems, investigates the effect of the system parameters on the system’s stability and focuses on poorly-damped conditions that may appear in the dc transmission.
