Instantaneous voltage dip hazard map on power system

In this paper, the authors propose a concept of the voltage dip hazard map. It visualizes the magnitude and occurrence probability of instantaneous voltage dips caused by lightning in consideration of the frequency distribution of lightning and all inter-connected networks on a system. This map clarifies the characteristics of voltage dips on a system from several aspects such as magnitude and occurrence probability of voltage dips at each consumer, the distribution of them on the system, and the relationship between regional lightning frequency and voltage dips. We show an example of the map using a ten generators model and verify the availability of the proposed concept.
