How does the saying go... “Those who do not learn history are doomed to repeat it.” Thomas Overbye, professor and director of the Texas A&M Engineering Experiment Station’s Smart Grid Center, is studying historical weather patterns to benefit the grid today. Weather information has been used in electric grid planning and operations since the 1880s but Overbye is looking to incorporate this information into the power or load flow of the grid. What will past weather events and patterns tell us about how to prepare the grid today?
