 Obiettivo del progetto (Objective)

'Eight Transmission System Operators (BE, CZ, FR, DE, IT, PT, CH, PL) and ENTSO-E, together with 4 associations of technology manufacturers, and 16 RTD performers propose a 3-year R&D project to develop and to apply a methodology for the long-term development of the Pan-European transmission network. The project aims at delivering a top-down methodology to support the planning from 2020 to 2050. First, it implements a set of future power scenarios, including generation units, the possible use of electricity storage and demand-side management solutions: scenarios for power localization are proposed with assumptions on the energy mix in each of the connected clusters covering the ENTSO-E area. Network studies are performed to detect the weak points when implementing the scenarios for 2050. Grid architectures options and a modular development plan are then proposed, including electricity highways, on the basis of power flow calculations, network stability analysis, socio-economic, network governance considerations, and with remarks from the consultation of European stakeholders. In parallel, an advanced planning methodology is designed, developed and tested with academic laboratories to address a few critical aspects of the above planning methodology, which may impact the robustness of the resulting architectures. This enhanced approach takes into account the correlated uncertainties in renewable generation and consumption, potential voltage and stability issues, and black-out risks including the feasibility of defence plans to avoid uncontrolled cascading failures of the candidate architectures. It includes the use of non-linear detailed models of power grids and stochastic optimization techniques. The dissemination is coordinated by ENTSO-E to reach the widest audience and to prepare the exploitation of the results. Standardization and complementary research efforts are pointed out for the future investment optimization with the support of the manufacturing industry.'

Introduzione (Teaser)

An EU-funded project is planning the development of the pan-European power transmission network, including possible highways, to meet European energy needs between 2020 and 2050.

Descrizione progetto (Article)

The rapid expansion of renewable electricity sources and demand-side management technologies in Europe is going to change the way transmission systems are designed and operated. Electricity should be transported over longer distances, across national borders, in order to connect renewable electricity production located far from the main European consumption areas. Active demand response services might also be controlled over large geographical areas, therefore involving many stakeholders under different regulatory regimes.

A pan-European infrastructure is thus required to enable more power and data exchanges between the different stakeholders of the power system, in order to comply with these new constraints including the progressive construction of a single European electricity market. This requirement for the development of a pan-European transmission network is addressed by the http://www.e-highway2050.eu/ (E-HIGHWAY2050) (Modular development plan of the pan-European transmission system 2050) project supported by the European Commission (DG Research).

The main objective of the project is the development of a methodology to support the planning of the pan-European transmission network up to 2050. This planning approach is in line with the European energy policy objectives to ensure the reliable delivery of renewable electricity and the pan-European electricity market integration. For this foresight exercise, five European power system scenarios have been developed.

The resulting modular development plan (to be delivered by the end of 2015) will depict the route towards different pan-European grid architectures, addressing each of the five scenarios which impact the pan-European transmission network most. The construction of the modular development plan involves a consortium of transmission system operators, research institutes, universities, industry associations and a non-governmental organisation.

The newly developed top-down methodology is built around six interrelated technical Work Packages (WPs) according to the following steps: scenario definition, scenario development/European grid model, system simulations, grid development, roadmap. In parallel with this step-by-step approach, the possibility to mathematically formalise such long-term planning methods is investigated using enhanced optimisation and advanced simulation tools.

Communication and dissemination work includes a website, a description of the project outputs in a dedicated report and a knowledge corpus of results which will be available on the on-line EEGI http://www.gridinnovation-on-line.eu (database), consultation workshops (with external stakeholders), exploitation workshops, as well as a final conference (November 2015). A constant flow of articles has been submitted to journals and conferences and several presentations of e-Highway2050 have been made during key events.
