Abstract
In the method for closed-loop control of at least two converters in an energy transmission and/or distribution system, each rectifier regulator and each inverter regulator provides a differential DC voltage from the difference between a given set DC voltage and the relevant received measured DC voltage, and also provides a differential DC current from a differential DC current from the difference between a set DC current and the corresponding received measured DC current. Each converter is a self-commutated converter with power semiconductors. The rectifier regulation of the provided converter is regulated such that the sum of the product of the differential voltages and the value of given set DC current at the corresponding rectifier and the differential current is a minimum. The inverter regulation regulates the corresponding inverter such that the sum between the differential voltage and the differential current is a minimum.
