DMC490 Configuration
25
Output Enabled This setting indicates if the storage output/discharge is set to
be included in the microgrid optimization calculations by the
DMC490. For hydrogen storage, which is interpreted as the
combination of electrolyzer, high-pressure storage cylinders,
and fuel cell, enabling the output translates to enabling the
fuel cell.

Storage Type
Specify if the storage is batteries or a hydrogen-based system,
such as the combination of electrolyzer, high-pressure storage
cylinders, and fuel cell.

Maximum
Discharging
Power (kW)
Specify the maximum electrical power in kW that the storage
unit can discharge to the microgrid. For hydrogen storage,
which is interpreted as the combination of electrolyzer, high-
pressure storage cylinders, and fuel cell, this setting refers to
the rated power of a fuel cell.

Discharging
Power (kW)
Specify the minimum electrical power in kW that the storage
unit is to discharge to the microgrid. For hydrogen storage,
which is interpreted as the combination of electrolyzer, high-
pressure storage cylinders, and fuel cell, this setting refers to
the minimum fuel cell output power.

Charging Power
(kW)
Specify the maximum input/charging power of the storage
unit in kW. For hydrogen storage, which is interpreted as the
combination of electrolyzer, high-pressure storage cylinders,
and fuel cell, this setting refers to the rated power of the
electrolyzer.

Charging Power
(kW)
Charging power for a storage device cannot be below a
certain level, so Specify the minimum input/charging power of
the storage unit. This power level is related to the technology
and specifications of the storage device itself and it does not
depend on other dispatchable or renewable devices in the
system. For hydrogen storage, which is interpreted as the
combination of electrolyzer, high-pressure storage cylinders,
and fuel cell, this setting refers to the minimum input power of
the electrolyzer.
For example, for a 300 kW alkaline electrolyzer, this setting
can be in the range of 120 to 130 kW.

Charging
Efficiency (%)
This setting describes how efficient the input or charging
power over time contributes in increasing the state of charge.
Charging efficiency depends on the input/charging power and
storage state of charge. However, it is assumed here to be a
fixed setting, which is acceptable in most applications. For
hydrogen storage, which is interpreted as the combination of
electrolyzer, high-pressure storage cylinders, and fuel cell, this
setting refers to the electrolyzer efficiency. (The charging
efficiency of the storage cylinders is close to unity.)

Discharging
Efficiency (%)
This setting describes how efficient the stored energy is
converted back to the microgrid. Discharging efficiency
depends on the output/discharging power and storage state
of charge. However, it is assumed here to be a fixed setting,
which is acceptable in most applications. For hydrogen
storage, which is interpreted as the combination of
electrolyzer, high-pressure storage cylinders, and fuel cell, this
setting refers to the fuel cell efficiency. (The discharging
efficiency of the storage cylinders is close to unity.)
