Abstract
An electrical chain-link converter system includes a converter phase leg for converting a plurality of DC electrical currents from a plurality of DC power sources to an AC current of an electrical power distribution network. The phase leg includes a plurality of serially connected converter cells each of which is connected to a respective power source of the plurality of DC power sources. The system also includes a control unit associated with the phase leg, the control unit including a processor; and a storage unit storing instructions that, when executed by the processor, cause the control unit to, for each of the converter cells: obtain a dedicated voltage reference for the converter cell; and transmit the voltage reference to the converter cell.
