| Abstract: | Cascading failure research has great significance for blackout defense .Aiming at the difficulties and key technologies of system modeling , risk assessment , forewarning and vulnerability analysis about cascading failures , the research results at home and abroad are summarized .Firstly, the models of casca-ding failures are comparatively discussed in detail .Then risk assessment methods are categorized and il-lustrated .And the application situation related to gird security analysis of cascading failure is explained . Finally , by probing some challenges in need of urgent attention , the development tendency of cascading failure research is forecasted , with expectation to provide a scientific basis for grid security defense strate-gy under the new environment . |
