Abstract
The penetration of DG is increasing on distribution
networks across the world. As a result, networks are
being pushed closer to their operating limits. In particular,
voltage rise has been identified as a key barrier to further
DG capacity. Active management of the voltage constraint
may be possible, leading to a form of constraint management
at distribution level for the first time. Here a novel method is
proposed, which minimises the cost of curtailment. It takes
advantage of the dispatchable capability of certain forms of
DG, such as biomass, hydro or landfill gas. There are a number
of well established methods for congestion management
on the transmission network. A number of these are applied
to voltage management on the distribution network and used
for comparison with the new minimum cost method. The
variability of voltage sensitivities andmarket prices is also investigated,
with their impact on the cost of curtailment quantified.
