The LVDC source (input voltage) of each converter is 4.04 kV, while the voltage drops across cables are responsible for different voltages at the output terminal of the wind turbines.
According to discrete time-domain modelling approach, the procedure is only valid when the variations in MVDC grid voltage [v.sub.o] (t) (output terminal voltage) and LVDC voltage [v.sub.g] (t) (input terminal voltage) in the event (switching) are relatively small than their initial and final values .
The procedure is only valid when the variation in output voltage [v.sub.o](i) (MVDC grid voltage) or input voltage [v.sub.g](i) (LVDC
voltage) in the event (switching) is relatively smaller than its initial and final values .

Most recently, Phoenix-based Jordan Spencer opened an 18,000-square-foot, multiline showroom in the LVDC
. The company carries brands including Lorts Manufacturing, Artitalia and Pearson Company,
