phys.org has an article on a study which investigates the improved stability that electric vehicles bring to the power grid.
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 regulation, and load balancing.
Now in a new study, researchers have found another potential advantage of using PEVs as sources of power for the grid: they can improve stability when the grid is subjected to large disturbances
This study appears to look at a two way communication mechanism between the grid and vehicles using low latency ethernet links to control power consumption - Vehicles can consume when there is surplus power, but can react to shortages by feeding return power back into the grid.
The results of the simulations show that PEVs can improve stability in two ways. First, they can reduce the speed and voltage fluctuations resulting from large disturbances by up to 80%. And second, they can extend the critical clearing times (after which the system will be unable to resume stable operation) by 20-40%. In general, the PEVs can begin to stabilize the grid within seconds of a large disturbance
The paper, published in the New Journal of Physics, is available for download.
