Project Final Report, Deliverable D9.2 of the iTesla Project

Abstract

This document is the final report of the iTesla project co-financed by the Seventh Framework Programme (FP7) of the European Union (Grant Agreement 283012). The iTesla project has developed a toolbox able to support the operation of the pan-European electricity transmission system in the coming years and has validated the different functionalities of this toolbox with datasets of various complexity and size. This toolbox has been designed to support the decision-making process from two-days ahead to real time and to take up the three main following challenges: - to provide a risk-based assessment taking into account the different sources of uncertainties, in particular, those brought by intermittent power generation, - to perform accurate security assessment taking into account the dynamics of the system using time-domain simulations, - to provide operators with relevant proposals of curative actions to keep the system in a secure state (such as generation redispatching, change in transformer tap position, topology of substations, set point values of HVDC lines or phase shift transformers (PST), change in the maintenance scheduling). In addition, the iTesla project has developed: - Methodologies and tools for validation of dynamic models of components of the pan-European system, using off-line analysis; these tools have been designed to determine model parameters using measured dynamic responses of the grid. - New concepts to build more robust defence plans and optimal restoration plans with the help of automated tools e.g. the integration of renewable energy resources (RES) and distributed energy resources (DER) and the use of time-synchronized measurements from phasor measurement units (PMUs). This report provides a summary of the main outcomes of the iTesla project but it does not enter deeply into technical and scientific details. All public project deliverables, publications and workshop materials can be downloaded from the project website: www.itesla-project.eu. Most of the iTesla outcomes are accessible to all, in particular: 1. The iTesla platform is available at https://github.com/itesla/ipst (MPL Mozilla Public License 2.0). 2. The computation modules are distributed by the iTesla partners either as open source software or as commercial products. 3. The RaPId software for model validation is an open source software (under the GNU LGPL v3 license) and is available at https://github.com/SmarTS-Lab/iTesla_RaPId . 4. The iTesla Power System Library of power system component models in the MODELICA language has been released open source (under the MPL 2.0) so that it can be used and enriched by TSOs and the whole power systems community. It is available at https://github.com/itesla/ipsl .
