ABSTRACT: Studying the dynamic behavior of electric power systems is important part of a power engineer’s work. Transient phenomena in electric power systems can be naturally and conveniently modelled as hybrid or event-continuous systems, which are a generalization of classical dynamical systems. The approach is illustrated by a model of a large electric power system with controllers and protective devices. An original event detection algorithm for explicit numerical methods with error and stability control is presented and used to simulate the model. The simulation results show that the approach can be successfully applied to modeling and simulation of electric power systems. The model was composed and simulated in the modeling and simulation environment ISMA.
