Innovative Tools for Electrical System Security within Large Areas

Release of the Open Source code of the iTesla platform on Github

Download the validation handbook here. This handbook aims to facilitate the validation of the iTesla toolbox. It compiles the commands made available and describes the validation method. This document is meant to evolve regularly along with the evolutions of the platform.


The iTesla project aims at improving network operations with a new security assessment tool able to cope with increasingly uncertain operating conditions and take advantage of the growing flexibility of the grid.
The developed toolbox should support the decision making process for network operation from two-days ahead to real time, based on three main features:

  • provide a risk-based assessment taking into account the different sources of uncertainties (in particular intermittent power generation), the probabilities of contingencies and the possible failures of corrective actions;
  • perform accurate security assessment taking into account the dynamics of the system using time-domain simulations;
  • provide operators with relevant proposals of preventive and curative actions to keep the system in a secure state.

The toolbox will allow TSOs to address network simulations of their own system, of coordinated regional systems or of the whole Pan-European system.

iTesla is a collaborative R&D project co-funded by the EC 7th Framework Programme. Coordinated by RTE, it gathers 6 TSOs (Belgium, France, Greece, Norway, Portugal and Great Britain), a coordination center (CORESO) and a pool of 13 universities and R&D providers. The total budget is 19.4 M€ with 13.2 M€ financing by the EC. The project, started in 2012, will be completed in December 2015.
