A control system 400 for a power plant 100, 101 is provided, wherein the power plant includes a medium voltage (MV) power line 30. The control system is configured to influence actual high voltage (HV) characteristics of an HV power line 20 at a point-of-interconnection to a grid. The control system includes an MV-compliant measurement system configured for connection with the MV power line 30 of the power plant. The MV-compliant measurement system 410 includes at least one of a voltage measurement device configured for measuring the voltage on the MV power line and a current measurement device configured for measuring the current on the MV power line. The control system 400 further includes an evaluation unit 420. The evaluation unit 420 is connected to the MV-compliant measurement system 410 and is configured to calculate HV characteristics of the HV power line based on measurement values received from the MV-compliant measurement system at the MV power line 30 and based on a model of a transformer 40. The transformer 40 transforms from medium voltage on the MV power line 30 to high voltage on the HV power line 20. The evaluation unit 420 is configured to generate a control signal based on the calculated HV characteristics in order to control the power plant for influencing the actual HV characteristics of the HV power line 20. |
