IntelliTeam® DEM Distributed
Energy Management System
for managing the S&C PureWave®
Community Energy Storage System
S&C’s IntelliTeam® DEM Distributed Energy Management System
The IntelliTeam® DEM Distributed Energy
Management System can manage a fleet of up to
one thousand S&C PureWave® Community Energy
Storage Units. The aggregation of energy storage
units can defer—or eliminate—the need for additional
build-out of an electrical utility distribution system to
handle peak power consumption needs at the feeder,
substation, or system level.
PureWave Community Energy Storage Unit.
The self-contained, rack-mountable IntelliTeam
DEM Controller is typically installed in the utility
distribution substation, and communicates with the
energy storage units, as well as the SCADA system, if
applicable, through DNP 3.0.
The controller features an easy-to-use interface
based on IntelliTeam® Designer—the main setup tool
for S&C’s field-proven IntelliTeam® SG Automatic
Restoration System. The interface offers a detailed
“dashboard” view of each energy storage unit, and
can also provide access to a distribution management
system or other utility enterprise system.
Multiple Applications, Multiple Benefits
IntelliTeam DEM Controller software allows the
single-phase energy storage units to simultaneously
perform a variety of functions, including:
• Peak shaving/load leveling.
• Renewable generation integration. The energy
storage units store excess energy produced by
consumers’ small-scale renewable generators, and
are dispatched as needed to meet peak power
demands.
• Reactive power compensation. The energy
storage units are dispatched as needed to supply
real or reactive power, simultaneously, on a perphase basis, to improve phase balance.

Voltage optimization. The energy storage units
are dispatched as needed to regulate feeder
voltages.
Reliability improvement. The energy storage
units are dispatched as needed to supply backup
power to consumers.
A Scalable, Balanced Solution
A major advantage of community energy storage is
its scalability. The number of energy storage units
in a fleet can be small initially, and grow over time
to offset load growth . . . pacing capital outlay in a
measured, controllable manner. The IntelliTeam DEM
Controller can readily accommodate this growth with
its ability to manage up to 1000 energy storage units.
Fully Automated Charging and
Discharging
The IntelliTeam DEM Controller provides fully
automated charging and discharging of each energy
storage unit, individually, using either of two
approaches:
• Scheduled. Charging and discharging are
performed at scheduled times each day of
the week.
• Load following. Charging and discharging are
performed as needed, to maintain target demand at
the feeder and substation transformer levels.
A sophisticated algorithm optimizes the power
output of the entire fleet based on the charge state
of each available energy storage unit. The algorithm
takes into consideration the energy which will be
needed if an outage occurs, and operation in islanding
mode is effected.
Alternately, the energy storage units may be
individually commanded by personnel in the utility
distribution operations center, to charge or discharge
at a particular rate.
High Reliability, Minimal Maintenance
The IntelliTeam DEM Controller has been designed
for utmost reliability. The controller features
redundant processors and data storage, and nonvolatile random-access memory. Configuration
settings and operational data are all replicated and
saved, in near real time, to a database at a remote
location, for use if recovery is ever necessary. The
controller has no moving parts such as disk drives
or fans.
The IntelliTeam DEM Controller accepts two
power sources—a primary and a secondary—in a
wide range of ac and dc voltages. The controller will
automatically power up when one of the sources is
available, allowing automatic recovery if both sources
are lost and one source subsequently returns.
The IntelliTeam DEM Controller uses IP network
time as its primary time source, with GPS as its
secondary time source and an on-board clock as its
tertiary time source.
Software upgrades can be performed locally,
through USB, serial, or Ethernet connection, or
remotely over any communication medium that
supports DNP 3.0.
Highly Secure
IntelliTeam DEM Controller architecture is highly
secure. User authentication and multiple user roles
and access levels are supported.
Quality
IntelliTeam DEM Controller is manufactured by S&C
in an ISO 9001 certified facility. Thousands of S&C
controls are in use worldwide.
