| Abstract(in English) | This paper shows a numerical method for predicting voltage instability of a power system based on reachability analysis of hybrid systems. The analysis is performed by computing reachable sets of unsafe sets in nonlinear hybrid automata that represent both continuous voltage dynamics and discrete operations by relay devices. The unsafe sets here are subsets of state space in which a system voltage shows unacceptable levels such as very low or high values. Then transient voltage instability can be estimated by investigating whether a system state exists in the reachable sets or not. The estimation is possible at any time in operation, for examples, onset time of relay operations. This paper numerically demonstrates the proposed method via an analysis of single-machine load bus system. |
