摘要
Abstract
In accordance with the stability of blackout events caused by cascading failures, a method of analyzing time-varying angle stability of power system considering cascading failure for multi-operation conditions was proposed based on cascading failures.Firstly, with protection/breaker uncertain movements, hardware failures and other random events considered, the possible states could be determined based on flow transferring relativity factor and transition probability matrix between states can be obtained.On this basis, the discrete Markov power system model of multi-operation condition considering cascading failure was established. And Lyapunov functional including discrete Markov power system model of multi-operation condition was constructed. Iterative method was used to deduce robust stochastic stability criterion, which meets interference decay rateγ Furthermore, the problem of feasibility of linear matrix inequalities (LMI) was used to solve the system stability problem.Time-domain simulation results of IEEE 16-machine 68-bus system show that the proposed method is effective in determining the stability of power system of multi-operation condition without the trajectory and reduces the calculation amount and is easy to be put into practice compared with traditional time-domain simulation method.关键词
