Massive InteGRATion   of power Electronic devices
By 2020, several areas of the HVAC pan-European transmission system will be operated with extremely high penetrations of Power Electronics(PE)- interfaced generators, thus becoming the only generating units for some periods of the day or of the year – due to renewable (wind, solar) electricity. This will result in

  1. growing dynamic stability issues for the power system (possibly a new major barrier against future renewable penetration),
  2. the necessity to upgrade existing protection schemes and
  3. measures to mitigate the resulting degradation of power quality due to harmonics propagation.

European TSOs from Estonia, Finland, France, Germany, Iceland, Ireland, Italy, Netherlands, Slovenia, Spain and UK have joined to address such challenges with manufacturers (GE, Schneider Electric) and universities/research centres. They propose innovative solutions to progressively adjust the HVAC system operations.

Firstly, a replicable methodology is developed for appraising the distance of any EU 28 control zone to instability due to PE proliferation and for monitoring it in real time, along with a portfolio of incremental improvements of existing technologies (the tuning of controllers, a pilot test of wide-area control techniques and the upgrading of protection devices with impacts on the present grid codes). Next, innovative power system control laws are designed to cope with the lack of synchronous machines. Numerical simulations and laboratory tests deliver promising control solutions together with recommendations for new PE grid connection rules and the development of a novel protection technology and mitigation of the foreseen power quality disturbances. Technology and economic impacts of such innovations are quantified together with barriers to be overcome in order to recommend future deployment scenarios. Dissemination activities support the deployment schemes of the project outputs based on knowledge sharing among targeted stakeholders at EC level.

The ‘Best Paths’ Project aims to overcome the challenges of integrating renewable energies into Europe’s energy mix. It aims to develop novel network technologies to increase the pan-European transmission network capacity and electricity system flexibility. The project unites expert partners around five large-scale demonstrations to validate the technical feasibility, costs, impacts and benefits of the tested grid technologies. The focus of the demonstrations is to deliver solutions to allow for transition from High Voltage Direct Current (HVDC) lines to HVDC grids, to upgrade and repower existing Alternating Current (AC) parts of the network, and to integrate superconducting high power DC links within AC meshed network.

Power system reliability management means to take decisions under increasing uncertainty (for instance, related to renewable generation). It aims at maintaining power system performance at a desired level, while minimising the socio-economic costs of keeping the power system at that performance level.

Seven TSOs (Belgium, Bulgaria, Czech Republic, Denmark, France, Iceland, Norway), together with twelve RTD performers and one innovation management expert work with the 4-year GARPUR research project in order to design, develop, assess and evaluate new system reliability criteria and management to be progressively implemented over the next decades at a pan-European level, while maximising social welfare.

The MEDOW consortium is made up of eleven partners (five universities and six industrial organisations). Each institution in the consortium contributes various expertise on the manufacturing, design, operation, and control of multi-terminal DC grids.

A DC grid based on multi-terminal voltage-source converter is a newly emerging technology, which is particularly suitable for the connection of offshore wind farms.  Multi-terminal DC grids will be the key technology for the European offshore ‘supergrid’.

This project will recruit twelve early-stage researchers (ESRs) and five experienced researchers (ERs).  In addition to their individual scientific projects, all fellows will benefit from further interdisciplinary and intersectoral education, which includes internships and secondments, a variety of training modules as well as transferable skills courses and active participation in workshops and conferences.

MEDOW offers a development path to researchers across Europe in the area of DC grids, in addition to fostering greater ties between industry and academia in this key development area.

The iTesla project aims at improving network operations with a new security assessment tool able to cope with increasingly uncertain operating conditions and take advantage of the growing flexibility of the grid. The developed toolbox should support the decision making process for network operation from two-days ahead to real time, based on three main features:

  • provide a risk-based assessment taking into account the different sources of uncertainties (in particular intermittent power generation), the probabilities of contingencies and the possible failures of corrective actions;
  • perform accurate security assessment taking into account the dynamics of the system using time-domain simulations;
  • provide operators with relevant proposals of preventive and curative actions to keep the system in a secure state.

The ‘e-Highway2050’ Project’s main objective was to develop a top-down planning methodology to provide a first version of a modular and robust expansion plan for the Pan-European Transmission Network from 2020 to 2050, in line with the pillars of European energy policy. The main findings of the project included:

  • New methodologies for the development of the European transmission grid have been developed, enabling to:
  • Address long term horizons,
  • Cover the whole Europe,
  • Cope with the European low carbon objectives, translated at national, and local levels, while building global grid architectures   
  • An invariant set of transmission requirements has been identified in consistency, and in continuity with the Ten-Year Network Development Plan conducted by ENTSO-E. Their benefits for the European system, resulting from the optimal use of energy sources, largely exceed their costs.
  • The proposed architectures integrate the present pan-European transmission grid, without needing a new separate ‘layer’ within this existing transmission network.

Within the frame of the ‘Twenties’ Project a group of transmission system operator from various European countries linked with generator companies, power technology manufactures and research & development found out that:

  • Europe’s energy structure can be used a lot more efficiently than it currently is. The most important findings include:
  • Wind  farms  can  provide  wide  area  voltage  control, and  secondary  frequency  control  services  to  the system
  • Virtual power plants enables reliable delivery of an-cillary services, like voltage control and reserves, by intelligent control of distributed generation including wind farms and industrial consumption
  • A DC circuit breaker prototype was tested successfully
  • By applying ‘high wind ride through control’, reserve requirements are cut in half
  • By using Real Time Thermal Rating (RTTR) or Dynamic Line Rating (DLR) for measuring and forecasting overhead  line  capacity,  10%  more  flow  in  average can go through equipped overhead lines;
  • By using the combined effect of DLR and power flow controlling  devices  to  control  the  flows  in  the  European grid, more wind in-feed can be integrated in the existing grid without jeopardizing the system security;
  • By controlling flows by means of PSTs, HVDCs and FACTS, local congestions can be alleviated in a flexible manner. A smart control of a set of such devices enable getting even more out of the existing grids

OffshoreGrid was a techno-economic study within the Intelligent Energy Europe programme. It has developed a scientific view on an offshore grid in northern Europe along with a suitable regulatory framework that takes technical, economic, policy and regulatory aspects into account. The following aspects were among the key findings:

  • Detailed offshore wind power scenarios with generation time series for Northern Europe and high-level renewable energy and grid scenarios for the Mediterranean region.
  • Interaction of different design drivers for an offshore grid and the associated costs and interaction of power prices, market design and energy economic parameters in a market comprising the regions around the Baltic and North Sea.
  • The interim report discusses the clustering of wind farms at hubs versus radial connections to the shore, the possibility of teeing in offshore wind farms to planned interconnectors, and the integration of wind farm hubs with interconnectors in meshed grids;

Offshore wind energy deployment can significantly contribute to increasing the share of renewable energy in Europe's energy mix. However, competing uses of the sea, costs, grid integration and other barriers are important challenges to the development of offshore wind. (Belgium, Denmark, Germany, the Netherlands, Norway and the UK). The  WINDSPEED  project  has  carried  out  an assessment  of  (ambitious  but  realistic)  deployment  potentials  under  different  scenarios  to  gain  better insight  into  how  key  uncertainties  can  impact  on  OWE  developments. The WINDSPEED project concludes that a capacity of 135 GW of OWE in the Central and Southern North Sea  is  feasible  by 2030. To  achieve  135 GW  OWE  in  the  Central  and  Southern  North  Sea  by  2030,  countries  must  be  willing  to both increase spatial prioritisation to OWE (closer to shore) and establish an offshore grid. In order to do so, greater coordination between countries is necessary.

ENTSO-E, the European Network of Transmission System Operators, represents 42 electricity transmission system operators (TSOs) from 35 countries across Europe. ENTSO-E was established and given legal mandates by the EU’s Third Legislative Package for the Internal Energy Market in 2009, which aims at further liberalising the gas and electricity markets in the EU.

The role of Transmission System Operators has considerably evolved with the Third Energy Package. Due to unbundling and the liberalisation of the energy market TSOs have become the meeting place for the various players to interact on the market place.

ENTSO-E objectives

ENTSO-E members share the objective of setting up the internal energy market and ensuring its optimal functioning, and of supporting the ambitious European energy and climate agenda. One of the important issues on today’s agenda is the integration of a high degree of Renewables in Europe’s energy system, the development of consecutive flexibility, and a much more customer centric approach than in the past.

ENTSO-E is committed to develop the most suitable responses to the challenge of a changing power system while maintaining security of supply. Innovation, a market based approach, customer focus, stakeholder focus, security of supply, flexibility, and regional cooperation are key to ENTSO-E’s agenda.
