Choose the engine per study — pandapower, OpenDSS, or ANDES. Full documentation →
Results are driven by mature open engines and checked against commercial tools and independent academic work.
pandapower power flow and short-circuit results are validated against DIgSILENT PowerFactory and PSS Sincal with strict tolerances — continuous CI on every change.
pandapower validation →Master’s thesis work at the University of Palermo compared Electrisim with Neplan across load flow and short circuit.
Read the study →Offshore wind load flow is cross-checked through pandapower and OpenDSS on the same model — consistent results across two major solvers.
Read dual-solver article →Results driven by pandapower, OpenDSS, and ANDES — continuously validated against commercial tools, including independent university studies.
Read validation →Draw networks in the browser, run simulations, export engineering report PDFs. No IT tickets for license servers or USB dongles.
Need air-gapped or offline? Deploy the free Community Edition from GitHub under Apache 2.0.
Get the code →Many engineers run Electrisim for day-to-day studies and keep a commercial seat only where contracts require it.
