Gray, David Thomas Chalmer (2004) Impact of demand-side management on substations. [USQ Project]
With the significant increase in the consumption of electricity over the past few years, it has
been hard for electricity entities to keep up with the sudden increases in demand. The
replacement and upgrade of substation transformers and associated equipment is very
expensive and time consuming to obtain and install. Also the wanton use of electricity
without understanding the consequences and its impact on the environment is negligent
on the part of the individual.
For the purpose of this project Demand-Side Management is any action taken to reduce the
consumption of electricity supply to a customers premises, to assist an Electricity Entity
in the stability of the electricity network. This leads to the principle that Demand-Side
Management can be used to defer capital expenditure by attempting to average a feeder
or substation load over a longer period and reduce the amount of peaks and troughs.
As will be seen later in the report, air-conditioning load is one of the fastest growing
domestic loads, with significant increases over the past 2 to 3 years. As a result the
electricity networks are being overloaded due to the unexpected increase in electricity
There are many different methods of demand-side management mentioned in this
report, most of these can be used to manage air-conditioner load, however the methods
would not be acceptable to customers.
After looking at various forms of demand-side management I believe that congestion
pricing is the method that is most suitable and fair for managing customers airconditioning
load. Congestion pricing operates similar to tariff control, however the
difference is that electricity prices are increased during high demand periods.
Voluntary Load Shedding should be encouraged amongst those industrial organisations
that can defer their load times. As such congestion pricing and voluntary load shedding
are two methods of demand-side management that need to be seriously considered by
Irrespective of what type of demand-side management method employed, for demand-side
management to be effective the customer must actively support it.
