OpenDSS (Open Distribution System Simulator) is an open-source software maintained and distributed by EPRI (Electric Power Research Institute). Completely open source and free.
It's made with distributed generation in mind and performs power flow studies, fault analysis, and harmonic...
Project consists of a 3-phase 95kW solar PV plant connected to a 12.47kV distribution line. The 480V inverter's isolation transformer is connected delta-wye with high-resistance grounding.

Thanks for your input and experiences tlrols...very helpful! I downloaded the trial and fired up PowerWorld for the first time in years. Forgot how much more intuitive it this than the other platforms.
I think for my purposes, this may suit me best. It looks like we will be contracting out the...
Thanks for the analysis tlrols. It's good to get some perspective outside of what I normally use (PSLF and PSS/E). I overlooked PowerWorld as an option as I haven't used that since university; I'll definitely be looking into that..
I'm working in the United States, everywhere from Hawaii to New...
GE has a quick study on modeling inverter DG on their PSLF site.
Of course, the study is mostly geared towards performing steady-state and dynamic studies in PSLF but it has some info on low voltage ride through and a quick bit on fault analysis.

Most of my experience is with GE's PSLF software as a transmission operations engineer. I have some exposure to Siemen's PSS/E and wanted to get some opinions of pros/cons of differing software from those wiser than I.
The company I work for now is looking to select a power system software for...
