| Electricity power systems are critical to any country's economy and security. Blackout, the most severe form of power loss to a relatively wide area, posting tremendous societal consequences, could be resulted from different causes from failure fault at a power transmission line to an intentional attack. Therefore, it is of importance to study the behavior of power grid (a complex network) during power blackout with its failure pattern. Based on these findings, we can find the suitable plan for normal daily management/expansion, emergency response and restoration after blackout. However, there are many schools of scholars using different ways to model the Blackout phenomenon, with different conclusions. Since those researches are done over several decades, it is important to organize them in a systematic way so that it could help the future research. Also, several minmax optimization models are proposed with different scenarios to represent the impact of blackout. |
