Online reliability calculations of power systems with forecasted and real time weather influence

Most reliability assessments use fault statistics that averages the number of fault contingencies over the year. This statistics makes double or triple fault contingencies highly improbable, and thus the impacts of such contingencies are often disregarded. But few faults in the power grid occur on an average day with average weather conditions. Extreme weather conditions can affect large areas and will significantly increase the probability of faults, and thus making double contingencies much more probable.

  • Online reliability calculations and the importance of including weather data in such calculations.
  • A presentation of the online risk tool Promaps Online, currently running simulation of the Norwegian power system.
  • The principles and background behind the reliability calculations
  • The strong correlation between faults on power lines and wind strengths.
