Analysis of Dual-Infeed HVDC With LCC–HVDC and VSC–HVDC
IEEE Transactions on Power Delivery, 2012 Summary form only given. The impact of a Voltage Sourced Converter based HVDC (VSC-HVDC) infeed on a line- commutated converter based HVDC infeed (LCC-HVDC) at the same busbar is investigated. Steady state aspects such as the maximum available power (MAP) as well as transient aspects such as temporary overvoltage (TOV) and “Commutation Failure Immunity

The Area Comparison of LCC-HVDC and VSC-HVDC [PDF]
Science Discovery, 2017 With the mature of high power IGBT, VSC-HVDC technique is gradually adopted in principle power grid with higher voltage and capacity. At present, it is generally considered that compared with traditional HVDC technique, VSC-HVDC will save lots of land resources. However, it is not always the case.
