Sažetak
Voltage Source Converter based High Voltage Direct Current (VSC HVDC) transmission lines are used more and more in modern power systems. Consequently, in the ac network, an increasing number of converters appear in mutual electrical proximity. These are called Multi- Infeed (MI)-HVDC systems. For VSC technology, several aspects of MI-HVDC system operation are less understood compared to Line Commutated Converter (LCC) HVDC systems. This paper studies a MI system which consists of two VSC HVDC schemes based on Modular Multilevel Converters (MMC) interconnected with an ac line and connected to an external grid. The focus of the study is on identifying the small-signal stability properties of such system, thereby focusing on the impact of different outer control loops for reactive power and ac voltage regulation.
