Teleport

Balancing services

FCR

FCR services can be activated using the deliverFCR property of the SetBatteryOperation command. At the moment FCR is only supported on battery brands for which this is explicitly mentioned.

aFRR

aFRR can be activated using the applyAfrrDeltaSetpoint command. It must be pre-configured by the withthegrid team and is available for batteries, solar and wind. The reference signal is available in setpoints.desired.activePower.afrr.reference of the forwarded data objects (or equivalent for non-JSON based forwarding destinations).

Some caveats:

  • The Teleport requires an accurate available active power estimate, which is not always available on Solar assets. In that case one or more irradiance sensors or pyranometers need to be installed and calibrated.
  • Solar assets are often controlled through a logger and/or are connected in a string by means of serial communication. This can worsen the response time significantly, up to the point that they cannot by themselves meet the aFRR the delivery tolerances specified by the TSO. Such solar assets are therefore only recommended in an aFRR pool that has enough independently distributed energy producing assets.
  • Wind turbines have long response times, active power is quite variable and the available active power estimate often has a significant error. It is therefore in most cases impossible to keep a single turbine within the aFRR delivery tolerances specified by the TSO. Turbines are therefore only recommended in an aFRR pool that has enough independently distributed energy producing assets (which can still consist of only wind turbines).

mFRR

The applyAfrrDeltaSetpoint command can also be used to activate mFRR.
