In modern power system, a single fault seldom leads to the catastrophe like blackout, but often causes other faults, which result in cascading failures and blackouts. Therefore simulate the cascading process of power system is more meaningful than a single device contingency analysis. Against such backgrounds, this paper proposes a method for cascading failure simulation with static security analysis...
A new islanding boundary searching approach based on slow coherency and graph theoretic is presented in this paper. During system Oscillation, generator groups are identified by slow coherency criterion firstly. Then after graph simplified, the multilevel k-way partition algorithm is adopted to compute the best islanding point. Finally, case analysis proves that this strategy is available for avoiding...
