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.

In this paper, we present a new Matlab-based toolbox for power system analysis, called MatDyn. It is open-source software, and available for everyone to download. Its design philosophy is based on the well-known open-source Matlab toolbox MATPOWER, but its focus is transient stability analysis and time-domain simulation of power systems, instead of steady-state calculations. calculations. MatDyn's philosophy, design criteria, program structure, and implementation are discussed in detail. A trade-off is achieved between the flexibility of the program and readability of the code. MatDyn retains overall flexibility by, for instance, allowing userdefined models, and custom integration methods. The software is validated by comparing its results with those obtained by the commercial grade power system analysis package, PSS/E. Despite the fact that MatDyn is fairly new, it has already been extensively used in research and education. This paper reports interesting results obtained with MatDyn in recent research that would be hard to obtain using commercial software. © 2011 IEEE. Source

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.

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).
