The growing share of electricity generation from intermittent renewable energy sources as well as increasing market-based cross border flows and related physical flows are leading to rising uncertainties in transmission network operation. In the mainland central Europe synchronous area due to large installations of renewable energy generation such as wind and photovoltaic, the difference between actual physical flows and the market exchanges can be very substantial. Remedial actions were identified by previous smart grid studies within the 6th European framework program in operational risk assessment, flow control and operational flexibility measures for this area. At the same time an efficient and sustainable electricity system requires an efficient usage of existing and future transmission capacities to provide a maximum of transportation possibilities. New interconnections and devices for load flow control will be integrated in future transmission networks and will offer new operational options. Further developments of coordinated grid security tools are one of the major challenges TSOs will face in future. The methods to be applied have to take into account all technological measures to enhance flexibility of power system operations. The zonal structure of the European energy market along with the legal responsibilities of TSOs for different system areas will continue to pose increasingly complex requirements to the system operators concerning the quality and accuracy of cooperation. The proposed UMBRELLA research and demonstration project is designed for coping with these challenging issues and boundary conditions. The toolbox to be developed will enable TSOs to ensure secure grid operation also in future electricity networks with high penetration of intermittent renewables. It enables TSOs to act in a coordinated European target system where regional strategies converge to ensure the best possible use of the European electricity infrastructure.

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.
