Abstract
This paper proposes the exploitation of MultiTerminal
HVDC grids to improve transfer capability in power
systems. Multi-Terminal HVDC systems based on voltage
source converters (VSC-MTDC) have been recognized as a
promising alternative for the wind power integration. Under low
wind scenarios, these grids originally dedicated for wind power
transmission can be exploited as an additional interarea transmission
path, providing extra dynamic security. The paper focuses
on small-signal stability assessment, especially in poor
damped oscillations associated with interarea modes. Simulations
performed through a generic computational framework
have shown that the high level of flexibility and controllability
provided by voltage source converters can considerably improve
the transfer capacity, while preserving adequate dynamic performance.
