> (Phys.org) —Today when an electric vehicle is plugged into the grid, it's > almost always in charge mode, meaning it consumes power.

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. Large disturbances are caused by > a wide range of problems, such as abrupt load changes and line tripping. > Among their negative effects, they can damage sensitive appliances and, if > not cleared within a specific time, the system may be unable to resume stable > operation. When the time comes, I'm going to be asking questions here about how to do that on a small scale, with a charger / inverter / whatever combination to provide backup power for the home. But I've got plenty more to worry about before then.... b& _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
