Remote Fixed Value

This function controls the plant to output reactive power according to the target value remotely set by the third-party dispatch system.

  1. Choose Energy management > Grid-connected reactive power.
  2. Set Function enable/disable.

    • Enable: Enable the reactive power control function. Proceed to subsequent configurations.

    • Disable: Disable the reactive power control function.

  3. Select the Remote fixed value mode.
  4. Configure the following parameters:

    Parameter

    Description

    		 Value
    Dispatched object It defines the closed-loop point for the remotely set value.
    • Grid connection point (default): The remotely set value in reactive power control will be used to perform closed-loop control for the power at the grid connection point.
    • Energy storage system: The remotely set value in reactive power control will be used to perform closed-loop control for the ESS.
    Remotely set value (Mvar)

    Displays the reactive power value remotely set by the third-party dispatch system.

    		 Display only. No configuration is required.
    Control deadband (kvar)

    It defines the range within which the target reactive power value can fluctuate.

    For example, if the target reactive power at the grid connection point is set to 10 kvar, and the deadband is set to 5 kvar, then the actual reactive power may fluctuate between 5 kvar and 15 kvar during operation, which is within the acceptable range.

    		 Range: [0, max (10, 0.03 × ESS rated power)]. 3.000 by default.
  5. Click Apply settings. In the pop-up window, enter the Task name, then click Confirm.
