Electrisim’s pandapower engine is continuously tested against DIgSILENT PowerFactory and PSS Sincal. We also publish dual-solver and independent university validation work.
pandapower power flow and short-circuit results are validated against PowerFactory with strict tolerances on voltage, angles, and loading — continuous CI on every change.
pandapower validation →Our benchmark article walks through how open-source power flow tools compare with PowerFactory on real cases.
Read the benchmark →Master’s thesis work at the University of Palermo compared Electrisim with Neplan across load flow and short circuit.
