Abstract
Plug-in electrical vehicles (PEV) are capable of both grid-to-vehicle (G2V)
and vehicle-to-grid (V2G) power transfer. The advantages of developing
V2G include an additional revenue stream for cleaner vehicles, increased
stability and reliability of the electric grid, lower electric system costs, and
eventually, inexpensive storage and backup for renewable electricity. Here
we show how smart control of PEVs can improve the stability of power grids
using only local frequency measurements. We evaluate the proposed control
strategy on the IEEE Case 3 and the IEEE New England power systems. The
results show that V2G leads to improved steady-state stability, larger region
of stability, reduced frequency and voltage fluctuations during transients and
longer critical clearing times.
