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.
No fees for using the application when run locally. Developed by enthusiastic power system engineers, software developers and supported by our great community.
The calculation algorithm is based on the Pandapower application, 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.
Just click the start button and model, simulate and analyse electrical network using our cloud application.
We are listening to the needs of people, who use the application in order to make it better each day. Please give us your feedback.
We invite you to collaborate to the development of the Electrisim application. If you’d like to run the software locally, you’ll need to deploy it on your computer.

The vision of the Electrisim Team is to provide a tool for electrical engineers to analyze electrical systems without the need to buy expensive commercial license and with no need to install dedicated software.
"Power flow solver is based on the Newton-Raphson method. The implementation was originally based on PYPOWER, but has been improved with respect to robustness, runtime and usability.' The backward/forward sweep, Iwamoto, fast decoupled and Gauss-Seidel methods are also available.
"The application includes a short-circuit calculation that allows to calculate fault currents for three-phase, two-phase and single phase short-circuits according to the IEC 60909 standard. The implementation also allows modeling power converter elements, such as PV plants or wind parks, according to the 2016 revision of the standard."
"Optimal power flow can be constrained by either AC or DC loadflow equations. The branch constraints represent the maximum apparent power loading of transformers and the maximum line current loadings. The bus constraints can contain maximum and minimum voltage magnitude and angle. ."
"You can define N-1 cases to be analysed as contingencies. This means that line and transformers can be selected for contingencies and switched off one at a time. The power system is analyzed with power flow calculations, and the min/max values among all the N-1 cases are obtained for relevant variables."
"The control module allows to simulate elements that are controlled based on power flows in power systems. Prominent examples are tap changer controllers that adapt the tap changer of a transformer depending on a measured bus voltage, or droop controllers in PV plants that adapt the reactive power depending on the bus voltage."
"The time series module is designed for the simulation of time based operations and is linked to the control module. Within a time series simulation controllers are used to update values of different elements in each time step in a loop."
