Abstract :
Depending upon the charging technique, fleets of PHEVs integrated within the power grid behave as constant power loads (CPL) or constant impedance loads (CIL). In this paper, a small-signal stability analysis of a power system with high PHEV penetration is performed. The results indicate that when the PHEVs are charged with a constant-current technique, the grid is more prone to instability. Consequently, operating PHEVs as CILs can increase their maximum penetration levels before the system becomes unstable.
