AFTER project addresses the challenges posed by the need for vulnerability evaluation and contin-gency planning of the energy grids and energy plants considering also the relevant ICT systems used in protection and control. Project emphasis is on cascading events that can cause catastrophic outages of the electric power systems. The main addressed problems are related to high impact wide spread multiple contingencies, the most significant wide area criticality. This kind of contingencies and the following cascading effects can be caused by deliberate acts of terrorism, sabotage, criminal activity, malicious behaviour etc or they can simply be caused by a combination of accidents, natural disasters, negli-gence. Both risk analysis and risk mitigation will be pursued. In particular, two major objectives are addressed. The first is to develop a methodology and tool for the integrated, global vulnerability analysis and risk assessment of the interconnected Electrical Power Systems considering their interdependencies. This objective meets the TSO (Transmission System Operator) need to overcome current approaches based on separate evaluations of either power system or ICT system. Further, the adoption of risk concepts allows a more in-depth, quantitative evaluation of the security of the electrical power system. The second objective is to develop algorithms and tools supporting contingency planning in a two-fold approach: preventing or limiting system disruption, by means of physical security techniques and defence plans; and re-establishing the system after a major disruption, by means of restoration plans. To this aim, AFTER propose the use of the global risk assessment methodologies as a support to defence plan design. A language to model defence plans functionalities and ICT architecture is de-veloped. New defence plan concepts are also introduced to cope with emergency situations.

The significant rise in distributed renewable energy sources has placed an enormous burden on the secure operation of the electrical grid, impacting both the transmission system operators (TSOs) and distribution system operators (DSOs). The massive increase of the intermittent DRES in low (LV) and medium (MV) networks has led to a bidirectional power flow which raises the urgent need for new operational and control strategies in order to maintain the ability of the system to provide the consumers with reliable supply of electricity at an acceptable power quality level. Technically, INCREASE will focus on how to manage renewable energy sources in LV and MV networks, to provide ancillary services (towards DSO, but also TSOs), in particular voltage control and the provision of reserve. INCREASE will investigate the regulatory framework, grid code structure and ancillary market mechanisms, and propose adjustments to facilitate successful provisioning of ancillary services that are necessary for the operation of the electricity grid, including flexible market products. INCREASE will enable DRES and loads to go beyond just exchanging power with the grid which will enable the DSO to evolve from a congestion manager to capacity manager. This will result in a more efficient exploitation of the current grid capacity, thus facilitating higher DRES penetration at reduced cost. Because of the more efficient use of the existing infrastructure, grid tariffs could decrease, potentially resulting in a lower cost for the consumers. The INCREASE simulation platform will enable the validation of the proposed solutions and provides the DSOs with a tool they can use to investigate the influence of DRES on their distribution network. The INCREASE solutions will also be validated (i) by lab tests, as well as (ii) in three field trials in the real-life operational distribution network of Stromnetz Steiermark in Austria, of Elektro Gorenjska in Slovenia and of Liander in the Netherlands.

6 Transmission System Operators (Belgium, France, Greece, Norway, Portugal and United Kingdom) and CORESO, a TSO coordination centre, together with 13 RTD performers propose a 4 year R&D project to develop and to validate an open interoperable toolbox which will bring support, by 2015, to future operations of the pan-European electricity transmission network, thus favouring increased coordination/harmonisation of operating procedures among network operators. Under the coordination of RTE, new concepts, methods and tools are developed to define security limits of the pan European system and to quantify the distance between an operating point and its nearest security boundary: this requires building its most likely description and developing a risk based security assessment accounting for its dynamic behaviour. The chain of resulting tools meets 3 overarching functional goals: i) to provide a risk based security assessment accounting for uncertainties around the most likely state, for probabilities of contingencies and for corresponding preventive and corrective actions. ii) to construct more realistic states of any system (taking into account its dynamics) over different time frames (real-time, intraday, day ahead, etc.). iii) to assess system security using time domain simulations (with less approximation than when implementing current standard methods/tools). The prototype tool box is validated according to use cases of increasing complexity: static risk-based security approach at control zone level, dynamic security margins accounting for new power technologies (HVDC, PST, FACTS), use of data coming from off-line security screening rules into on-line security assessment, and finally security maps at pan European level. Dissemination is based on periodic workshops for a permanent user group of network operators invited to use modules to meet their own control zone needs and the ones of present or future coordination centres.

Power system reliability management means to take decisions under increasing uncertainty (for instance, related to renewable generation). It aims to maintain power system performance at a desired level, while minimizing 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 eleven RTD performers, propose the four year GARPUR research project. GARPUR designs, develops, assesses and evaluates new system reliability criteria and management while maximizing social welfare as they are progressively implemented over the next decades at a pan-European level. The new management methodologies encompass multiple business activities (system development, asset management, power system operation) that, in turn, ensure coherent decision-making at the respective time horizons. These methodologies also involve mathematical and computational models to predict the location, duration and amount of power supply interruptions. Five alternatives to improve reliability management of the pan-European power system are studied. After practical validation by the TSOs, these alternatives are analysed with the help of a quantification platform. Pilot tests of the new proposed reliability criteria are performed by individual TSOs or (when appropriate) a group of TSOs using this quantification platform, either in a given control zone or (where appropriate) throughout the pan-European system. Reliability criteria are compared and presented to the TSO community and regulatory authorities who establish the robustness of the results. Dissemination activities of the new reliability criteria are supported by a Reference Group of TSOs and address all the key electricity market stakeholders. An implementation roadmap is delivered for the deployment of the resulting technical and regulatory solutions to keep the pan-European system reliability at optimal socio-economic levels.

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.

The key objective of the EcoGrid EU project is to demonstrate efficient operation of a distribution power system with high penetration of many and variable renewable energy resources. The demonstration will take place on the Danish island Bornholm with more than 50 % of electricity consumption from renewable energy production. A real-time market concept will be developed to give small end-users of electricity and distributed renewable energy sources new options (and potential economic benefits) for offering TSOs additional balancing and ancillary services. Strong industrial participation and innovative experiences from related European and US Smart Grids RD&D project will contribute to the development and implementation of robust ICT platforms and information architectures. This is the key to allow all distributed energy resources to participate actively in the real-time power market. Of a total of 28 000 customers on Bornholm, at least 2600 residential consumers will participate with flexible demand response to real-time price signals. The participants will be equipped with residential demand response devices/appliances using gateways and smart controllers. Installation of the smart solutions will allow real-time prices to be presented to consumers and allow users to pre-program their automatic demand-response preferences, e.g. through different types of electricity price contracts. Automation and customer choice is one of the key elements in the EcoGrid EU concept. To make the EcoGrid EU solutions more widely applicable, the market concept will be designed for existing power exchange(s) and power regulation market(s). Because of the test site location on Bornholm, the real-time market concept will first be operational in the Nordic power market system. EcoGrid EU replication activities will ensure that the concept (or part of the solutions) can be adjusted and prepared for implementation in other power systems and regulatory conditions across Europe.

A group of 6 Transmission System Operators (Belgium, Denmark, France, Germany The Netherlands and Spain) with 2 generator companies, 5 manufacturers and research organisations, propose 6 demonstration projects to remove, in 3 years, several barriers which prevent the electric system from welcoming more wind electricity, and wind electricity from contributing more to the electric system. The full scale demonstrations aim at proving the benefits of novel technologies (most of them available from manufacturers) coupled with innovative system management approaches. The contribution of wind energy to the system will show how aggregated wind farms can provide system services (voltage and frequency control) in Spain. The aggregation of wind farms with flexible generation and loads will be demonstrated in Denmark using a scalable IT platform developed by a generator. Increasing the flexibility of transmission networks will be tested in Belgium (existing sensors and coordinated power flow control devices avoiding possible large scale instabilities induced by wind farms in the CWE region) and in Spain (dynamic wind power evacuation capacity using real-time computations based on short-term generation forecasts and use of a mobile Overload Line Controller). Off-shore wind farms are addressed from a security viewpoint. Secure HVDC meshed networks will be validated in France using simulations and full scale experiments of two different HVDC circuit breaker technologies. Off-shore wind farm shut downs under stormy conditions will be demonstrated in Denmark using the world largest off-shore wind farm with balancing power provided by the Norwegian hydro capacities through a HVDC link. The experimental results will be integrated into European impact analyses to show the scalability of the solutions: routes for replication will be provided with benefits for the pan European transmission network and the European electricity market as soon as 2014, in line with the SET plan objectives.

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. In this proposal, DC power flow, DC relaying protection, steady state operation, dynamic stability, fault-ride through capability, and impacts of DC grids on the operation of AC grids and power market will be studied. Systematic comparison of DC grid topologies and stability control strategies will be carried out. DC grids for offshore wind power transmission and onshore AC grid interconnection will be investigated. Operation and control will be evaluated using various simulation platforms and experimental test rigs. The achievements from the project will greatly contribute to integrating offshore wind power into the onshore AC grids in European countries and for the European Super Grid. The MEDOW consortium involves 11 partners (5 universities and 6 industrial organisations). Each institution in the consortium contributes various expertise on the manufacturing, design, operation, and control of multi-terminal DC grids. Three visiting scientists of outstanding international stature will be appointed to further strengthen the training capacity and quality of MEDOW. This project will recruit 12 early-stage researchers (ESRs) and 5 experienced researchers (ERs). These researchers will receive interdisciplinary and intersectoral trainings in different countries to improve career opportunities. Research results will be disseminated through publications, intellectual properties, and direct application in the industries. 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 objective of eStorage is to develop cost-effective solutions for the widespread deployment of flexible, reliable, GWh-scale storage across EU, and to enhance grid management systems to allow the integration of large share of renewable. The key issue we plan to address is the need for power regulation during low demand periods, when only inflexible baseload generation and intermittent renewable generation are operating. In contrast to conventional generation, a storage plant able to regulate its consumption could help to avoid curtailing wind. Conventional Pumped Storage Hydro Plants (PSP) can only regulate their power in generation mode; variable speed technology for PSP can bring the additional flexibility in pumping mode as well. Developing technically and economically feasible solutions in eStorage will allow upgrading a significant part of European PSP capacity to variable speed, providing up to 10 GW of additional regulation capability with no environmental impact and little administrative burden, all at a much lower cost than developing new plants. We will also develop and demonstrate solutions for coupling the dispatch of storage plants with renewable generation using advances Energy Management Systems. This will enable storage plants to maximise their value in the balancing markets.. From simulation studies, demonstration results and storage potential analysis we will evaluate the system-level benefits of storage and identify development barriers in order to draw recommendations for efficient market and regulatory framework to maximise the impact of project outcomes. eStorage gathers major stakeholders from the entire value chain across EU (Elia TSO, EDF Generation Company, Imperial College Academic Institution, Kema Engineering Consultancy and Alstom Equipment Manufacturer).

Five Transmission System Operators (Belgium, France, Germany and Spain) together with seven RTD performers propose a 3 year research and demonstration project to compare pros and cons of new market designs aiming at the integration of massive intermittent energy sources dispersed in several regional power markets. Under the technical coordination of RTE, they will implement a novel network/system/market modelling approach to provide the consortium with an open simulation platform able to exhibit the comparative benefits of several market design options. Such options may originate either from anyone of the four studied markets or from partners that have already worked for the UK or Danish electric systems. Market participants and TSO are players of such a simulation: each area is represented by aggregated realistic data over one year and system security rules are fulfilled at any time. The demonstration tasks require data with appropriate non disclosure agreements, in order to address first the market behaviour of fully rational players, and next the impact of non optimal behaviours, using agent modelling. Results will be compared (possibly ranked) before being packaged and presented to the TSO community and regulatory authorities for analysis of the platform potential and trustworthiness of the simulation results. This demonstration will be complemented by intensive dissemination activities towards the TSO community within EU27 and beyond, with dedicated trainings to accompany the take-up of the simulation platform. An exploitation agreement is proposed to further improve and expand the platform within the pan European TSO community, beyond the end of this project. Such a platform will help developing technical and regulatory solutions compatible with a virtual single European Grid and regional network management processes by assessing, through combined network and market modelling, the expected outputs of new market designs in support of the 2020 EU27 targets.
