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.

"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."
"The Open-Source Distribution System Simulator (OpenDSS) is a comprehensive electrical system simulation tool for electric utility distribution systems. It supports nearly all RMS steady-state (frequency domain) analyses commonly performed for utility distribution systems planning and analysis. OpenDSS features multiple solution modes including snapshot power flow, daily power flow, yearly power flow, harmonics, dynamics, fault study, and Monte Carlo analysis."
