Electric vehicles could stabilize large disturbances in power grid

(Phys.org) --Today when an electric vehicle is plugged into the grid, it's almost always in charge mode, meaning it consumes power. But it's also possible for an electric vehicle to operate in discharge mode, in which it acts as a giant battery and injects power into the grid when needed. Several recent studies have shown that plug-in electric vehicles (PEVs) operating as vehicle-to-grid (V2G) devices can offer advantages for the grid such as backup power for renewable energy sources, power regu...
