Challenges of implementing an EWQMS
EWQMS implementation encounters many challenges which
are specific to the system infrastructure, the system boundaries,
embedded energy and geographical configuration [Raucher et al.,
2008]. Although all EWQMS installations rely on similar structural
features, each one needs to be tailored to the specific system
characteristics, objectives and limitations or constraints of each
installation site. So far, only large utilities that are able to sustain
the financial burdens of an automated platform and are equipped
with sophisticated hardware and software have opted for EWQMS
control. In general, the EWQMS implementation progresses in
stages, first by optimizing the operation in control areas of the
distribution system that can be isolated, and then by progressively
expanding to the full network once the predicted savings and return
on investments have been validated. As an example, Table 4
shows the level of EWQMS implementation in selected
municipalities.
