DMC490 Microgrid Controller Software Configuration Guide
24
Assuming that the dispatchable resource follows the advice of the optimizer, the modes are usually
the same.
•
Availability
: Availability is declared by the generator. This field indicates if the generator can be
controlled by the MGC and included in the optimization problem solved by the MGC. An online
generator is not necessarily an available generator. The availability signal is built by the generator’s
local controller based on some parameters and is read by the MGC.
•
Net Meter Power
: This field indicates the power generation values in kW read from different
dispatchable generators in the system.
The following field mappings apply to the AO/DO control points that are to be mapped to the Microgrid
controller >

•
Start:
Start/stop is a command. When the MGC sends the start command, the generator comes online
after some time.
•
Output Isoch Mode
: This field indicates if the resource is in droop or isochronous mode.
For isochronous mode, there is an input and output isoch mode:
o
The input isoch mode is advice produced by the optimizer and issued to the dispatchable
asset.
o
The output isoch mode is the actual operating mode of the dispatchable asset.
Assuming that the dispatchable resource follows the advice of the optimizer, the modes are usually
the same.
•
Power Ref
: This field refers to the power reference points of dispatchable generators, in kW. Their
values are computed by the MGC dispatch algorithm.
•
Operation mode:
This is an Analog output which refers to the current microgrid operation mode of the
asset (as explained in section System Settings on page 19, see the Active Mode setting).
•
Watchdog:
This is a Digital Output command used to inform the asset that the MGC controller is
active. A Digital Output command is sent on this point with the value toggling between 0 and 1 every
10 seconds.
Storage Asset
Configure each electrical storage installation with settings such as capacity and cost.
Storage devices of the same type that are co-located are considered one storage device.

Input Enabled
This setting indicates if the storage input/charging is set to be
included in the microgrid optimization calculations by the
DMC490. When storage input is offline and the optimal
dispatch result indicates storage input usage above the
minimum storage input for equal to or longer than the
Charging Minimum Up Time
, then the storage input is started.
For hydrogen storage, which is interpreted as the combination
of electrolyzer, high-pressure storage cylinders, and fuel cell,
enabling the input translates to enabling the electrolyzer.
