Status Points
The following field mappings apply to the status and read only inputs that are to be mapped to the Microgrid
controller > CHP Asset configuration page
• Net Electric Meter Power: This field indicates the electric power generation values in kW read from
different co-generators in the system.
• Net Heat Meter Power: This field indicates the heat power generation values in kW read from different
co-generators in the system.
•
Electric Online: This field indicates if the co-generator is online or offline for electricity production. It is
not necessarily the same as being available for use in the MGC optimization calculations.
• Heat Online: This field indicates if the co-generator is online or offline for heat production. It is not
necessarily the same as being available for use in the MGC optimization calculations.
•
Electric Isoch Mode: This field indicates if the electricity-generating function of the co-generator is in
isochronous or droop mode.
• Electric Availability: Availability is declared by the co-generator. This field indicates if the co-generator
can be controlled by the MGC for electricity production and included in the optimization problem
solved by the MGC. An online co-generator is not necessarily an available co-generator. The availability
signal is built into the co-generator's local controller based on some parameters and is read by the
MGC.
The following field mappings apply to the AO/DO control points that are to be mapped to the Microgrid
controller > CHP Asset configuration page:
•
Electric Power Ref: This field refers to the electric power reference points of co-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 described 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.

Point Settings
Setting Description
Asset ID Unique asset ID assigned by the DMC490 MGC.
Name Specify the name of the asset.
Specify if the asset is to be included in the microgrid optimization
Enabled
calculations.
Rated Power (kW) Specify the maximum heat generation capacity of the boiler in kW.
Some manufacturers provide the rating in kW and otherwise use
the related handbooks or Internet to find an appropriate
conversion procedure.
Minimum Power Specify the preferred minimum heat power in kW that the boiler is
(kW) to generate.
