Because of these drawbacks in HVAC transmission, application of high voltage direct current (HVDC) has increased significantly [1,2,3] and HVDC transmission has become an economical choice for the transfer of high power over longer distances. In the early stage, the current source converter (CSC...
In HVAC systems, power flows along the path of least resistance, sometimes resulting in unequal power distribution across the transmission system. HVDC systems allow the operator to precisely control the flow across the circuit, alleviating issues on the wider power system. In 2023, global ...

The HVDC and HVAC transmission lines running on the same tower is a promising technology to improve the transmission capacity of an existing corridor. The ions generated by corona discharge of HVDC transmission lines will strengthen the ground-level electric field, which may endanger human exposure....
