Grid applications for energy storage
Grid connection of renewable generation
When connecting large wind farms to the
power grid, they will typically be
connected to weak grids. Issues such as:

steep power changes

voltage control

grid stability during and after faults and

frequency regulations
are areas where the new DynaPeaQ
system supports the wind farm.

Grid applications for energy storage
Backup power
DynaPeaQ continuously supports the grid
with reactive power and in case of
generation loss DynaPeaQ will push
active power into the grid until new
generation is available.

Grid applications for energy storage
Intermittent loads of a railway
Accelerating a heavy train can expose the
grid to a peak load that traditionally gave
rise to extensive capacity build out
investments. With DynaPeaQ the required
acceleration power is literary taken from
the train’s latest deceleration.

Grid applications for energy storage
Emergency and short-time power
In a distribution grid a compensator for
reactive power would typically provide for
power quality improvement. The energy
storage adds a whole range of new
functions.


In cases where local loading exceeds
grid capacity DynaPeaQ provides load
support

After black-out restoration, the Energy
Storage might be the starting point

For sensitive loads, the Energy Storage
can provide overbridging power
between outage and backup power


The Battery Technology selected for DynaPeaQ is the Liion Battery.

The development of Li-ion batteries benefits from the
present development of batteries for electrical vehicles.

Calendar life time is acceptable, more than 15 years

Charge / Discharge cycle life time is acceptable.

Typical single line diagram
Scalability
Project depending number of battery
strings is included. At a later stage, more
battery strings can be added, for higher
power and energy. Typically, converters
have margins due to reactive power
requirements.
Flexibility
Charging and discharging are fully flexible
to the extent that, according to need, high
power can be charged/discharged for a
short time (power applications), or low(er)
power for a long(er) time (energy
applications)
