DIE STADT ALS<br />
SPEICHER<br />
(CITY AS STORAGE)<br />
Virtual energy storage has been<br />
successfully demonstrated across<br />
two German cities, Herten and<br />
Wunsiedel. As part of a project,<br />
several small and medium-size<br />
prosumers and producers were<br />
bundled and participated in the<br />
energy markets. Both private<br />
and municipal plants formed<br />
part of the model, connecting<br />
households, electric vehicles and<br />
a public swimming pool, as great<br />
untapped storage capability lies<br />
in existing infrastructure.<br />
The virtual storage was<br />
adapted to market demand and<br />
participated in the spot market.<br />
This system could have a role<br />
to play in the rapidly changing<br />
energy supply sector with owners<br />
of CHP plants, heat pumps, night<br />
storage heating or PV-batteries<br />
motivated to promote clean<br />
energy systems.<br />

ESTABLISHMENT<br />
OF PILOT PROJECT<br />
ON GRID SCALE<br />
BATTERY ENERGY<br />
STORAGE SYSTEMS<br />
(BESS) OF DIFFERENT<br />
TECHNOLOGIES<br />
Recognising the increasing<br />
importance of Battery Energy<br />
Storage Systems in India,<br />
POWERGRID has established<br />
a pioneering pilot project<br />
demonstrating two battery<br />
storage system technologies<br />
(Advanced Lead Acid & Lithium<br />
Iron Phosphate) with battery<br />
management at Puducherry.<br />
The systems, of 250 kWh and<br />
500 kW in size, are installed in<br />
one location and connected<br />
with the same feeder to provide<br />
identical grid conditions. They<br />
can therefore be compared on<br />
various parameters like overall<br />
sizing, efficiency, auxiliary<br />
power consumption, operational<br />
difficulties and maintenance<br />
requirements. While the units<br />
are relatively small for large grid<br />
storage management, this could<br />
be advantageous in the future as<br />
grids become less centralised, as<br />
well as for off-grid locations.<br />
The inclusion of multiple storage<br />
technologies along with grid<br />
management software will<br />
provide valuable data to enable<br />
grid balancing and facilitate wider<br />
deployment of renewables.<br />
