Within OpenDSS, our distribution system combined our PV design outputs from Aurora with the existing loadshapes and lines from the given Nebraska files. Due to the sizing of our design, we had no issues with overloads or voltage violations. Our OpenDSS scripts began with definitions of the UNL Circuit and pulled existing loadshapes from the existing power source. We downloaded the corresponding irradiance and weather profiles for our Nebraska use case from NREL’s resources to aid in the distribution system analysis.

 

Next, new load shapes were added based on the simulated output .csv files generated within Aurora, which provided an annual dataset that did not, at any time, exceed the respective building’s electrical usage. With these loadshapes, PV systems were modelled for each design and placed on the associated building bus. For the Agricultural Field design, the nearby Law College bus was utilized.
