The Ordinances of Electrical Security Accident Emergency Disposal and Investigation published by State Council has made it clear that load shedding in the stability control system equals to load loss in the system fault. The excessively high ratio of area load shedding may result in severe accidents of high level in the power grid and responsibility should be taken after the accident. Hence the study of solving the problem of some emergencies which have low demand of time control by adjusting the divisional structure of the grid dynamically to decrease the load shedding amount is very necessary. When there are more than one dynamic divisional proposal to deal with the emergency, optimal one with multi-objective optimization should be taken. When the emergency cannot be solved only by dynamic divisional technology, to reduce the loss of the grid and consider the electric safety accidents, the coordination between dynamic division and the measurement of emergency load shedding should be taken into account. According to the simulations of actual cases, under the guarantee of safety system, the decrease of load loss and lower level of electrical accident can be true by adopting the coordination between dynamic division of the grid and load shedding.
