| Abstract |
Power flow controllers (PFC) or current flow controllers (CFC) are expected to be required in futureHVDC grids to control the current flows and avoid congestions. This work proposes a methodology toobtain the specifications, select the most suitable converter structure and perform the sizing of aninterline PFC. Then, the methodology is applied to a real HVDC grid case study, obtaining thespecifications, the selected converter structure and the sizing of the power electronic elements and the passive components. The results show that the PFC is a medium voltage converter with high current rating requiring some switches in series and interleaved branches. With such a series/parallelassociation, the main elements of the converter are available on the market except for the inductances which can be manufactured on-demand without major technical locks. |
