participating in local markets, including
testing the ability to replace system support
services
traditionally performed
by large generators. The pilot is based
in metropolitan Perth's outer southeast,
an area with recent rapid expansion in
residential construction. The location
was selected for its high PV penetration
(around 50%), and local distribution
system that experiences high voltages
during midday and high thermal load
during evening demand peaks.
The pilot seeks to test the value to
the network operator realized by managing
DERs as an alternative to network
augmentation.
As well as testing the technical
parameters to enable and orchestrate
DER participation, Project Symphony
will be important in setting customer
norms and developing acceptance of
DER orchestration. Testing customer
service offerings that manage DER generation
will provide valuable learnings
to support aggregation beyond the trial.
Following the pilot, capabilities will be
expanded across SWIS in a managed way
to integrate virtual power plants at scale
into SWIS. The DER Roadmap proposes
that aggregated DERs will begin participating
in the local wholesale energy market,
including the provision of essential
system services where capable, by 2023.
DER Roadmap: Customer
Engagement and Protections
Consumer engagement and customer protection
under emerging business models
make up the final theme of the roadmap.
Consumer Engagement
Central to the roadmap approach is delivering
the best outcomes for consumers.
Figure 5 outlines the current and future
opportunities for households regarding
DERs. The DER Roadmap actions will
open up future technologies and choices,
avoid expensive upgrades to the network,
and enable everyone to share in the benefits
of PVs and other forms of DERs. But
the current level of community understanding
of some energy concepts, such
as minimum demand issues and the need
to make changes to integrate DERs into
the power system, is low.
