Adapter Overview

The Weather Data adapter is responsible for pulling real-time and future forecast weather data for use by the DMS power flow analysis. This adapter is written in Python and needs Python3 to run. It only imports the data with a timestamp in the future. Any data with a timestamp prior to the current time is ignored by the adapter. The weather data is used within the DMS applications for multiple purposes.

1. To drive the load forecast used by the power flow analysis. The weather data will be used to set which load profile is used by the real-time and forecast power flow solutions. Note: This assumes that temperature based load profiles have been configured.

2. To drive the DER forecast used by the power flow analysis. The weather data will be used to set which profile is used for weather affected DERs (for example, Solar, Wind, and so on).

3. The weather data will be archived in the NMS PF_DERMS_FORECAST_HISTORY database table such that it can be used by the NMS Profile Adapter to determine historical weather conditions for a particular weather zone. The Profile Adapter uses historical weather to categorize load profiles into their associated temperature bands. The historical information is also used to remove DER contributions from Net Metered load profiles such that the true load profile can be extracted and stored within the NMS database, the Profile Adapter chapter will describe this processing in more detail.
