Introduction: The pan European transmission grid will have to be reengineered progressively in order to accompany the electric system decarbonisation, shaped by a first set of intermediate targets in 2020. This long term transition will make transmission networks more and more complex with impacts on normal and emergency operations.

1. Much larger power transfers over longer distance

2. Predicting accurately the scheduling of power plants across Europe will become more difficult, which, inturn, will require conventional generators to balance the whole system.

3. With the rapidly increasing penetration of renewable electricity generation and the difficulty to build new overhead power lines, each TSO in Europe will no longer be able to comply with the classical preventive N-1 security standard year round.

4. When operating a power system close to its stability limits, unstable dynamic phenomena may appear after contingency. The standard static security assessment based on power flow calculations is no longer sufficient.

Objectives:

The overarching goal of the iTESLA project is to develop and validate an open interoperable toolbox able to support the future operation of the Pan-European grid.

Expected Benefits: This project will bring forward a major innovation: carry out operational dynamic simulations in the frame of a full probabilistic approach, thus going further that the current “N-1” approach and optimizing the transit capacities of the grid at different spatial (national, regional, Pan-European) and time (two-days ahead, day-ahead, intra-day, real-time) scales.
