Electrisim vs PowerWorld Simulator

PowerWorld Simulator is a well-known Windows tool for transmission power flow, widely used in teaching. Electrisim covers the everyday studies in the browser, with distribution and safety studies included.

Feature Electrisim Typical desktop transmission tools (e.g. PowerWorld Simulator)
Monthly cost $10 per month Personal
$40 per user per month Company		 Commercial licences; several analysis tools are separate add-ons
Runs on Any modern browser: Windows, macOS, Linux Windows desktop
Load flow / power flow pandapower + OpenDSS
N-1 contingency analysis
Optimal power flow Included Add-on
Short circuit IEC 60909, ANSI/IEEE C37 (beta), OpenDSS
Transient stability & eigenvalues ANDES, included Add-on (transient stability)
Unbalanced distribution networks OpenDSS Focus on balanced transmission studies
Arc flash (IEEE 1584-2018) Not a focus
Harmonic analysis Not a focus
Academic use $40 per institution per month, many users Educational versions with bus limits
Open source Apache 2.0

Studies you can run instead of PowerWorld

Choose the engine per study — pandapower, OpenDSS, or ANDES. Full documentation →

Validated against commercial software

Results are driven by mature open engines and checked against commercial tools and independent academic work.

Commercial-tool validation

pandapower power flow and short-circuit results are validated against DIgSILENT PowerFactory and PSS Sincal with strict tolerances — continuous CI on every change.

Independent thesis study

Master’s thesis work at the University of Palermo compared Electrisim with Neplan across load flow and short circuit.

Dual-solver checks

Offshore wind load flow is cross-checked through pandapower and OpenDSS on the same model — consistent results across two major solvers.

When Electrisim is the right PowerWorld alternative

Best fit for

  • Students and lecturers who want a browser tool for power system courses, with one academic licence per institution
  • Consultants running load flow, contingency, OPF and short circuit on project networks
  • Engineers on macOS or Linux, or anyone who cannot install desktop software
  • Researchers who want open engines they can inspect and script (pandapower, OpenDSS, ANDES)

Still use PowerWorld when you need

  • Very large interconnection planning cases already built in PowerWorld or PSS/E formats
  • Specialist transmission tools such as transfer capability or geomagnetically induced current studies
  • Interactive contour and animated-flow displays your team relies on
  • Client or utility mandates that name PowerWorld

Many engineers run Electrisim for day-to-day studies and keep a commercial seat only where contracts require it.

PowerWorld alternative FAQ

  • For load flow, N-1 contingency, optimal power flow, short circuit and transient stability on project-sized networks, yes. Electrisim runs pandapower, OpenDSS and ANDES in the browser. It does not replace every specialist PowerWorld add-on, or very large interconnection planning cases.
  • Yes. The editor is free to explore in the browser, and the Academic licence costs $40 per institution per month for students, teaching and research, with several users working in the same account at the same time. The engines are open source, so students can see how the results are computed.
  • Yes. It runs in any modern browser on Windows, macOS or Linux. You can also self-host the free open-source Community Edition.
  • Not directly. Electrisim imports pandapower (.py) and OpenDSS (.dss) files and draws the single-line diagram for you. Cases from other tools have to be converted to one of those formats first; pandapower includes converters for formats such as MATPOWER.
  • Cloud Personal is $10 per month, Company $40 per user per month and Academic $40 per institution per month, and you can cancel anytime. The Community Edition is free. PowerWorld Simulator is sold as commercial licences, with several analysis tools as separate add-ons.
