A novel approach of real-time DSR rapid calculation

Although the precision of existing calculation methods of the dynamic security region can reach a high level, the heavy calculation and large time-consuming become the bottleneck of its online application. Based on the fact that fault location can affect the transfer of boundary hyper-plane, a method of real-time DSR rapid calculation - the angle uniform rotation method is proposed. By calculating angles of DSR hyper-planes in different fault locations, using the law that angles change in approximate linear, a new dynamic security region in another fault location is obtained. With the help of IEEE 4-generator 11-bus system, an acceptable error is obtained, which proves that the proposed method can improve the speed and accuracy of calculation of dynamic security region.
