Model an electrical system, perform simulation and analyse results in a secure cloud application. You can also run the software locally - check the open-source code. Currently, the power flow, short circuit analysis, optimal power flow, contingency analysis, controller simulation and time series simulation are available. More to come soon.
Working only in a desktop web browser. Not working on mobile phones.
Completely free to use when deployed locally. Built by passionate power engineers and developers, Electrisim democratizes access to professional-grade power system analysis tools for everyone.
The calculation algorithms are based on Pandapower and OpenDSS (beta), which proved to give the same results as other renowned power system analysis software. The Electrisim application is tested by numerous scenarios to verify the proper results.
Security provided by the top-tier Google Cloud solution. The security mechanisms are based on the highest standards: ISO 27001, ISO 22301, ISO 27017, ISO 27018 oraz CSA STAR
User-friendly graphical user interface (owing to Diagrams.net), based on drag-and-drop functionality for creating electrical diagrams.
Use instantly in your browser with our cloud application, or deploy locally on your computer for complete data privacy and offline capabilities.

Power flow solver based on the Newton-Raphson method. The implementation was originally based on PYPOWER, but has been improved with respect to robustness, runtime and usability. Backward/forward sweep, Iwamoto, fast decoupled and Gauss-Seidel methods are also available.
Short-circuit calculation with two engine options: Pandapower (IEC 60909) for three-phase, two-phase and single-phase fault currents with power converter modeling (PV, wind); and OpenDSS fault study for conventional fault analysis on all buses.
Optimal power flow constrained by AC or DC loadflow equations. Branch constraints represent maximum apparent power loading of transformers and line current loadings. Bus constraints cover voltage magnitude and angle limits.
Define N-1 cases as contingencies. Lines and transformers can be switched off one at a time. Power flow calculations determine min/max values among all N-1 cases for relevant variables.
The control module simulates elements controlled by power flows. Examples: tap changer controllers adapting transformer tap based on bus voltage, or droop controllers in PV plants adapting reactive power based on bus voltage.
Time-based simulation linked to the control module. Controllers update element values in each time step in a loop, ideal for daily or seasonal analysis.
Comprehensive electrical system simulation for utility distribution systems. Supports RMS steady-state analyses including snapshot, daily, yearly power flow, harmonics, dynamics, fault study, and Monte Carlo analysis.
Fault study computes fault currents and short-circuit impedances at every bus. Use Solve Mode=FaultStudy for initial symmetrical short-circuit current (I″k), peak current (ip), thermal current (Ith), and Rk, Xk. Select the OpenDSS tab in the Short Circuit dialog.
Computes voltage and current harmonic distortion. Use Solve Mode=Harmonic in the Power Flow dialog. Specify harmonic orders (e.g. 3, 5, 7, 11, 13) and view magnitude spectra. Supports harmonic loads (TCR, HVDC spectra), single-tuned filters, and THD results.
