In order to reduce or avoid the bad effects which contain scant data

fuzzy message

improper control measures produced by multilevel control

a new control mode based on multi-agent system

which has two management levels

is proposed.A new control mode is not only has a unique structure that is different from the accepted one which has three-level for voltage control

but also considers the characteristic of present power network management condition.Its control is mainly found on regional area control.Meanwhile

three typical abnormal situations which often happen in power grid are proposed and analyzed

and are solved well by regional cooperating control.At last

the result of simulation test shows the validity of the new control mode.
