Just about everything you need

GridCal started in 2015 with a clear objective: create a solid programming library and a user-friendly interface. This straightforward approach sparked many innovations — some driven by the necessity for commercial use, and others fueled by curiosity and research.

Whether you're a pro needing free tools, a researcher wanting a real-world tested platform, a teacher sharing commercial-grade software insights, or a student diving into practical algorithms, GridCal's got your back. It's a high quality product made for all of us now and for the future generations.

Power Flow

State of the art power flow algorithms tested on real life grids. GridCal power flow has the guarantee of convergence if there is a solution.

Optimal Power Flow

Linear optimal dispatch in DC and AC approximation modes. It can be split by months, weeks, days and hours to speed up the simulation. The results can be seamlessly feed back into the AC time series with one click.

Continuation Power Flow

Newton-Raphson corrector-predictor algorithm with reactive power control.

Soon, with AC/DC and more controls.

User interface

GridCal's intuitive interface is something unusual for a guild where the norm are overcrowded interfaces with zillions of buttons and configuration files. Better if we keep-it-simple right?

Effortless maps

Your results in a map for a presentation?
Easy peasy. GridCal features web-based maps for any result that you can represent on the schematic. It also features a special import interface for node coordinates.

Grid generator

When you're doing research, sometimes you need new grids. The random grid generator got you covered!

Stochastic power flow

Monte Carlo and Latin Hypercube sampling from the distributions set by the time series profiles. No need to assume distributions or data rules!


Short circuit

Three phase and unbalanced sequence short circuits.

Sigma analysis

Don't you know what this is? that's because it's bleeding edge tech.

Sigma analysis is a one-step proxy for voltage distance to the collapse.

Linear analysis

PTDF and LODF for blazingly fast screening.


Contingency analysis

Usage of the LODF based linear analysis for full blown contingency analysis leveraging all the power of multi-core machines.


Input data analysis

How many times have you failed to see a silly input data mistake? GridCal's input data analysis helps you out with expert rules.
