Title: Research on Improved Manchester Cascading Failure Model and Its Application
Abstract: Based on Manchester model and optimal power flow (OPF),an improved cascading failure model is established. This model describes cascading failure process by two different time scales,i.e.,the fast dynamics and the slow dynamics. In this paper the blackout risk of power system is evaluated by expected energy not supplied (EENS). The analysis on a certain regional power network in China,which is taken as a calculation example,is conducted; the impacts of system load factor and the fault rates of key-lines on blackout risk of power network as well as the power law process under critical load are researched. The results of this research is available for reference to the personnel engaging in system planning and operation to analyze the process of cascading failures and to adopt effective measures to reduce the blackout risk.
