Relationship between Weather Parameters and Transmission System Resilience

This paper provides results of assessment of the Bulk Power System (BPS) resilience against diverse types of extreme weather observed in Florida. For four Florida locations with high population density we analyze detailed weather data and their relationship to frequency of forced transmission outages and transmission unavailability, quantify adverse impacts of different weather parameters to the grid and rank the parameters by these impacts. Finally, we derive functional relationships that characterize the resilience of transmission system against high winds, wind gusts, excessive hourly and accumulated precipitation.
