In China, with the development of projects such as ＂electricity transmission from the West to the East＂ and ＂power exchange between the South and the North＂, and with the UHV project being put into operation, a nation-wide interconnection system has been formed. For such big interconnection system, local faults or disturbances might lead to large-scale power blackouts and even system collapses, which will cause direct and indirect losses comparable to a big natural disaster. By taking proper and reasonable controlled partition measures, the risk of long-period and large-area power failure and even system collapse will be greatly reduced. However, with the system size increasing, the number of partition interface will grow geometrically, and therefore, it is a great challenge for a nation-wide interconnection system to achieve the optimal partition surface.
