The document discusses the BNL Dew Model Server program which is a community modeling effort led by Brookhaven National Laboratory. The model server maintains integrated system models in memory 24/7 and allows for shared models and experimental measurements from multiple organizations around the world. It currently includes modified IEEE standard transmission and distribution models as well as models of long transmission lines and interconnected distribution feeders that are under construction.
