  Wireless dynamic charging technologies are becoming a promising alternative
solution to plug-in ones as they allow on-the-move charging for electric
vehicles. From a power network point of view, this type of charging makes
electric vehicles a new type of loads--the moving loads. Such moving loads are
different from the traditional loads as they may change their locations
constantly in the grids. To study the effect of these moving loads on power
distribution grids, this work focuses on the steady-state analysis of
electrified roads equipped with wireless dynamic charging. In particular, the
voltage profile and the long-term voltage stability of the electrified roads
are considered. Unusual shapes of the voltage profile are observed such as the
half-leaf veins for a one-way road and the harp-like shape for a two-way road.
Voltage swings are also detected while the vehicles move in the two-way road
configuration. As for the long-term voltage stability, continuation power flow
is used to characterize the maximum length of a road as well as the maximum
number of vehicles that the road can accommodate.
