DMC490 Configuration
43
Dispatch Time
(Minutes)
This setting is the optimization time resolution. It specifies the
frequency at which the DMC490 generates a data file based
on the collected information from the microgrid, solves the
optimization problem, and update commands for the
resources in the microgrid. Select a value that ensures no
more than 240 points are generated based on the Prediction
Horizon .
For example, for a 48-hour Prediction Horizon , the minimum
value that can be set for Dispatch Time is 12 minutes (that is,
48 hours / 12 min utes = 240).
The HMI panel reflects this setting as the Time to Next
Command Update .
The DMC490 MGC concludes the microgrid optimal solution
within two minutes. Depending on the number of assets in
the microgrid, inappropriate setting of Prediction Horizon
and Dispatch Time can lead to the violation of this two-
minute time limit, which initiates an alarm. For microgrids
with a relatively large number of assets, reduce the
Prediction Horizon and/or increase the Dispatch Time from
the default values. As an example, for a microgrid with eight
dispatchables, two renewables, and one hydrogen storage
(including electrolyzer, high-pressure storage cylinders, and
fuel cell), the optimal solution is found in less than 80 seconds
based on the default values for Prediction Horizon (24 hours)
and Dispatch Time (12 minutes).

Command Scheduler Settings
Configure the startup and shutdown time intervals for:
• Dispatchable resources and
• Storage resources
Command Scheduler settings are used to apply optimal dispatch advice with a sequence that does not
endanger the microgrid stability and which has low impact on the microgrid voltage and frequency profile.

This setting is the time that the DMC490 waits after
sending the isochronous command to check if the
command has been implemented or not.

This setting is the minimum delay between starting
dispatchable units. This action always starts from the
largest unit to the smallest unit.
