| Abstract: |
| Power supply ability and operation profit have been promoted by increasing power grid interconnection, which also leads to a higher level of cascading failures risk. Large-scale blackout caused by cascading failures happened several times in recent years. It is quite meaningful to comprehensively analyze power system cascading failures theories, mathematical features and application scenarios. In this area, a series of theories and modeling methods both with academic and practical values have been proposed in the last ten years. First of all, the intensive study is performed for essential features of cascading failure process, as well as the internal and external impact factors and required information. After listing the major difficulties of modeling approach, a comprehensive technical review of related algorithm is presented, which thus is expected to offer a clear scope for the future research. Last but not least, for the further discussion, some practical software and cascading failures algorithm used in the foreign power system industry are consequently introduced, which is expected to provide enlightenment for the advanced application in the power grid operation in China. |
