Weather Information Webinar

While this is not a PowerWorld seminar, it is by PowerWorld co-Founder Tom Overbye and he will be previewing some of the new PowerWorld version 23 functionality for direct inclusion of weather information in the power flow.

Title: An Approach for the Direct Inclusion of Weather Information in the Power Flow

Date and Time: July 13, 2022, 3-4 pm Central Time

Abstract:  While it is widely recognized that weather impacts the power flow, historically weather information has only been implicitly included in this analysis. This presentation provides an approach for the direct inclusion of weather information in the power flow.  Key issues addressed include the availability of weather information sufficient for power flow analysis, the mapping of weather information to electric grid components, a flexible and extensible modeling approach for relating weather values to the power flow models, and the visualization of the weather impacts on the results. The approach is demonstrated on several different electric grids ranging in size from 7000 to 82,000 buses covering geographic footprints up the contiguous US.  Results are shown using weather data from several thousand stations ranging between the 1940’s and present day including comparing the cold weather that impacted Texas in 2021 with what occurred in January of 1949.
