    As the electric power demand increases, power systems become larger and more complex. To keep the reliability, preventive control is desired in power system operations. It is necessary to shift a system to a stable side beforehand using the preventive control, so that the system may be stable even for some disturbances. In this paper, we use RIDGE theory to judge the transient stability for the preventive control. We use the characteristics of RIDGE theory to judge transient stability, and the proposed method can judge the transient stability fast. Simulations are carried out using 3 machine 9 bus and 10 machine 47 bus systems to confirm the validity of the proposed method.
