| Abstract |
The purpose of this study is to reduce large-scale power systems to increase the efficiency of power-flow analysis calculation based on fault analysis, thereby improving the stability and reliability of the power system. Case studies demonstrate that it is possible to improve the calculation speed compared to existing power-flow analysis if the reduction of the system is optimized using the newly proposed power grid reduction technique. |
