The participation of photovoltaic (PV) plants in supporting the transient voltage caused by commutation failure in the line-commutated-converter-based high voltage direct current (LCC-HVDC) system is of great significance. as it can enhance the DC transmission ability. However. it is found that the grid-following (GFL) PV converters face the problem of mismatch between reactive power ... https://www.ealisboa.com/
