Abstract
A method for providing frequency balancing in a power network grid by an RBS of a radio communication network. The RBS includes one or more power supply units, PSUs, connected to the power network grid. The method includes detecting a deviation of a power network grid frequency measured in a PSU of the one or more PSUs, the power network grid frequency is measured upstream of a power factor correction, PFC, unit of the PSU, deactivating the one or more PSU in response to the detected deviation, determining one or more further PSU to be deactivated based on the detected deviation, the RBS is in a first frequency containment reserve, FCR, zone and the one or more further PSU are in a second FCR zone, other than the first FCR zone, and sending a deactivation indication to the determined one or more further PSU.
