Abstract
With the increased advent of VSC HVDC with long
DC transmission link in power systems, situations have arisen
and will be even more frequent in the future, where several
distributed generation will be connected on the DC-link for more
power transfer capability. As penetration level increases, there is
need to predict the limit before violation of voltage and power
instability on the DC transmission link and ensure that it does not
interfere with the main VSC HVDC system control. In this paper,
power sensitivity and algebraic technique is proposed to predict
the maximum DG penetration that can be accepted at a
particular location on the dc link of VSC HVDC transmission
system before violation of voltage and power stability
