Abstract

These days, there has been a growing interest in the importance of electricity in the human daily life. Importance of providing steady electricity from a power grid infrastructure has been continuously increased. However, the power grid infrastructure can fail by several reasons. The breakdown of a small part of the network can affect the whole. The electrical failure can spread in sequence while causing blackouts, and this process is called Cascading failure. Although extensive research has been carried out on this with DC approximated model, little attention has been paid to AC models. In this paper, we propose an AC flow model to conduct a simulation for cascading failure of an electrical power grid. South Korea's peak amount of electricity demand data is used for simulation. In conclusion, the flow of a power grid is calculated by the AC model which gives more realistic results than the DC model.
