Power control (without Hybrid EMS)

Last modified: 28 Feb 2025

The power control Overview page displays the values for active power, reactive power, and measured values at the grid connection point (= point of common coupling). A blue'Log XC is required to carry out power control functions.

Power control: basic approach

To use the blue'Log for power control, the following is one possible setup workflow. If you do not carry out the steps in this order, power control may not function properly. 

1. Configure operating data

   • See Operating data (without Hybrid EMS).

2. Plan your master-slave setup.

   • See Controller operation modes: standalone, master, slave

3. Configure active power and reactive power (if applicable).

   • See Active power (without Hybrid EMS) and Reactive power (without Hybrid EMS).

4. Activate power control.

   • See Active power (without Hybrid EMS) and Reactive power (without Hybrid EMS).

5. Create a report.

   • See Report (without Hybrid EMS)

6. Confirm that power control is working properly on the power control overview page.
