RESOURCES
PRODUCTION
Distributed energy resources (DER) consist
of small-scale energy generation and
energy storage units located at or near the
load site.
According to the International Energy Agency, DER are emerging
rapidly for multiple reasons. New engineering technologies,
materials, and designs improve the performance and extend the
range of locations for DER. Constructing new or modernizing
existing high voltage transmission lines for centralized generation
are expensive and challenging. Customer demand for reliability
has increased. Concerns for climate change have created a pull
for swift renewable energy penetration.

BENEFITS:
First, DER systems enable cogeneration and trigeneration, and
avoid high voltage and long distance transmission losses, thus
increasing overall efficiency.
Second, DER expand the use of renewable sources and siting is
easier as DER avoid the need of new high voltage transmission
capacity.
Third, DER can be built swiftly and capacity can be added easily
based on the incremental demands of energy.
Finally, DER systems are capable of providing reliable and
sustainable energy to consumers.

DER provide a multitude of services to utilities and
consumers that include
standby or primary generation,
storage,
peak shaving,
peak sharing,
base-load generation,
combined heating and power (CHP), or
combined cooling, heating and power (CCHP).

DISTRIBUTED =
“ISLAND MODE”
Distributed energy elements are
mainly the same as for basic
energy system.
Trend. Add new distributed energy
elements which takes advantages
which may provide exact location
or consumers.
