Artelys is proud to develop the operational power grid security analysis engine of the European CorNet program

17 February 2023

— Artelys has been selected to develop the computational engine at the heart of a pan-European operational power grid security analysis platform.

The CorNet program, launched jointly by Coreso and TSCNET, two Regional Coordination Centers (RCCs), aims to set up an operational security analysis platform for the European electricity network. One of the key tasks of RCCs is to coordinate exchanges between the different Transmission System Operators (TSOs) to ensure security of supply and facilitate cross border energy exchanges.

Artelys will develop and integrate the calculation engines necessary for the network security analysis within the Core, Italy North, SWE, and Hansa regions, as illustrated below, while its partner Unicorn will provide the platform supporting the processes.

To enable this operational coordination and ensure security of supply at the European level, TSOs continuously share information with the RCCs. Several times a day, each TSO publishes a representation of its network, called an Individual Grid Model (IGM), which represents the best-detailed forecast of its power grid for the next hours, up to one day ahead. These models are then merged by the RCCs to form Common Grid Models (CGM) representing the European power grid.

Once the common models are established, the security analysis developed by Artelys relying on the PowSyBl framework will be launched over a High-Performance Computing (HPC) cluster to simulate thousands of contingencies on the European grid (loss of a line, unavailability of a power plant, etc.) to determine if the grid is at risk if one of these events were to occur.

If the network would indeed be at risk, i.e. if operational constraints were to be violated (e.g. the power flow on a line after a given contingency would be larger than the maximum admissible flow), the RCCs would coordinate the TSOs response to identify and implement the necessary remedial actions to make sure that the grid will be operated within its safety limits.
