Abstract

In the UK, the Capacity to Customers (C2C) project
is underway to determine the potential benefits of increased
interconnection in distribution systems, combined with demand
side response technology. Managed contracts with customers,
i.e., the agreement that certain loads are interruptible following
system faults, allows distribution circuits to be loaded beyond the
limits presently required for security of supply. This potentially
permits load growth but avoids the cost and environmental
impact of conventional network reinforcement.
This paper provides the results of electrical system modelling
to quantify the benefits of the C2C operation, using actual circuit
data and typical load distributions. Based upon simulations of
these circuits, it is shown that increased interconnection generally
leads to minor improvements in electrical losses and system
voltage. By connecting managed (i.e., interruptible) loads, circuits
typically can be loaded significantly further than the present
practice in the UK—an average increase of 66% for radial
operation and 74% for interconnected systems.
