Abstract
A control system for a power plant is provided, configured to influence actual HV characteristics of an HV power line at a point-of-interconnection to a grid. The control system includes an MV-compliant measurement system configured for connection with an MV power line of the power plant, and an evaluation unit. The evaluation unit is connected to the MV-compliant measurement system and is configured to determine calculated HV characteristics of the HV power line based on measurement values received from the MV-compliant measurement system at the MV power line and based on a model of a transformer. The transformer transforms from medium voltage on the MV power line to high voltage on the HV power line. The evaluation unit 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.
