The energy sector has entered a period of major change which will continue for many years to come. The increasing proportion of electricity from renewable sources means that the architecture of the energy grid will have to support the distributed, in addition to the centralised, generation of energy and to adapt to a highly volatile supply e.g. from wind and solar generators. From the consumption perspective, electric vehicles will demand new load management patterns in the grids. At the same time, private and commercial consumers are being encouraged to reduce their energy use and electronics manufacturers are striving to reduce the energy use of their products. The energy supply will need to evolve into a dynamic system to provide the smart energy infrastructure needed to support society in 2020 and beyond.\n\nFuture Internet technologies will play a critical role in the development of Smart Energy infrastructures, enabling new functionality while reducing costs. In the FINSENY project, key actors from the ICT and energy sectors will team-up to identify the ICT requirements of Smart Energy Systems. This will lead to the definition of new solutions and standards, verified in a large scale pan-European Smart Energy trial. Project results will contribute to the emergence of a sustainable Smart Energy infrastructure, based on new products and services, to the benefit of all European citizens and the environment.\n\nAs part of the FI-PPP programme, FINSENY will intensively analyse energy-specific requirements together with the other FI-PPP projects, develop solutions to address these requirements, and prepare for a Smart Energy trial in phase two of the programme. The growing FINSENY Smart Grid Stakeholder Group will provide broad visibility of the on-going project work in the energy community, enhancing the acceptability of the project results and facilitating the development of the smart energy market.

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.

SEGRIDs main objective is to enhance the protection of smart grids against cyber-attacks. We do this by applying a risk management analysis approach to a number of smart grid use cases (the SEGRID use cases), which will define security requirements and determine gaps in current security technologies, standards and regulations. The identified gaps and the analysis itself will give input to the enhancement of risk assessment methodologies and the development of novel security measures for smart grids. We are convinced that SEGRID will deliver a major contribution to the protection of smart grids of 2020 against cyber-attacks by: Identifying threats and potential future cyber-attack pathways, for the SEGRID use cases; Determining the gap between currently available security standards, methods and measures for smart grids in order to derive which additional security methods and measures are required for the SEGRID use cases; Developing the necessary new security methods and measures for privacy, communication and system security in smart grids, to mitigate the threats found in the SEGRID use cases, evaluate and test them; Building up a realistic test environment (Security Integration Test Environment, SITE) to test and verify new security methods and measures; Evaluating and improving current risk management methodologies in order to make them optimally suited to identify and address the key risk factors of smart grids of 2020; Feeding the established results from the SEGRID project into European and global standardisation bodies, industry groups and smart grid suppliers and make sure that the project results fit the needs of those communities and raise awareness among stakeholders.

Energy efficiency becomes crucial for rational consumption of the available resources and reduction of the CO2 production. But the reduction of energy consumption as the only remedy is only a partial solution. Similar, applying more environment-neutral or renewable energy sources without smart management systems may even cause failures in the energy grid or at least cause the energy to be wasted. Introducing intelligent solutions that combine the control of energy production and consumption helps to achieve the best efficiency.However a successful application of such solutions faces problems due to human factors. The problem space is multidimensional, but can be abstracted as a combination of social, economic and technical aspects. The e-balance project will investigate their interdependencies and propose a solution that satisfies the defined requirements.The social, economic and technical aspects will be investigated in order to achieve a mature and holistic solution.The social aspects include:- Socio-technical development (user requirements and concerns),- Different levels of user participation (involvement) and means to increase it,- Barriers to conduct an effective solution,From the economic perspective the following aspects will be considered:- Development of new business opportunities,- Economic means to increase involvement,- Legislation reinforcements and corrective measures,And the technical solution will provide the following features respecting the socio-economic aspects:- Support for all kinds of energy source and storage,- Scalable, fine grained and decentralized energy balancing and demand prediction,- Security and privacy mechanisms,- Flexible accounting,- Increased reliability.The technical solution will be based on available state of the art results and will combine them according to the socio-economical requirements with necessary adaptation.The proposed energy management platform will be evaluated in realistic scenarios using real world set-ups in Alliander microgrid in Bronsbergen and EDP Smart Grid in Portugal, as well as in emulation.In order to stimulate the exploitation of the results we will provide a guide book and tools for parties interested in using our solution, to help them to estimate the improvements they can achieve for a given deployment as well as the costs they can expect.

This project is about the demonstration of very low energy buildings. In all demonstrations, the ambition is net zero carbon/energy or better (active or plus-energy house). The project paves the way for large scale implementation of energy neutral buildings/neighbourhoods as foreseen in the Energy Performance of Buildings directive and the pilots are running more than five years ahead of the goal of the EU, to have energy-neutral new build dwellings by the start of 2019. Common approach is: 1- Reduce demand, 2-Sustainable heat, 3- Local renewables for residual demand. In Amsterdam, an old harbour area close to the city center will be developed as a climate neutral, water-rich neighbourhood. SPLA Lyon-Confluence consider setting very ambitious energy targets for their P-Plot building : this building should have a balanced energy consumption calculated in primary energy. The Grnkullan & Hlan area will be registered and evaluated on multiple parameters within 10 eco topics before, during design and in the evaluation. The houses will be built as passive houses and supplemented with renewable energy supply making the houses ACTIVE. The three pilots have a total gross floor area of about 50000 m2. All set the standard for future developments. Within all demonstrations there is a strong emphasis on demonstration of competitive techniques like waste water heat recovery. Demonstrations of ICT-based inhabitant energy feedback systems are included. Existing systems are improved and new ones are developed. A system for neighbourhood load control will be developed and demonstrated. The project includes innovative building element development. Topics are building-integrated PV-panels, important for all the demonstration sites, and transmission controllable windows that have significant potential to reduce the building energy demand. Monitoring, an extensive dissemination program and a special effort on mutual learning and experience exchange are paer of the project.

Since the 1970s, CIGRE has conducted three worldwide surveys on high-voltage circuit-breaker (CB) reliability. The results of the last inquiry, published last year, are presented and compared with those of the former inquiries. With a focus on the CB's fundamental functions for the system, figures show the growth in reliability during the past decades. The reliability is expressed in failure per 100 CB years (CBY) or per 10\thinspace000 operating cycles for the relevant failure modes. The overall major failure rate improved largely from the first (1.58 per 100 CBY) to the second (0.67 per 100 CBY) to the third enquiry (0.30 per 100 CBY). The failure rate increases with higher voltage classes; GIS CBs have been shown to be twice as reliable and live tank CBs twice as bad as the average failure rate. Although improved, the mechanical operating mechanism is still the subassembly responsible for most failures; besides, CBs applied for frequent switching purposes show a higher failure rate than average. © 1986-2012 IEEE.

The CRISALIS project aims at providing new means to secure critical infrastructure environments from targeted attacks, carried out by resourceful and motivated individuals. The recent discovery of a malware called Stuxnet, show that these threats are already a reality. Their success in infiltrating Critical Infrastructure environments is calling attention on the ineffectiveness of standard security mechanisms at detecting them. Stuxnet is believed to have been operating undetected for almost one year leveraging multiple vulnerabilities that were previously unknown, and has been discovered only as a consequence to an operational anomaly that triggered the attention of the field operators. This fact clearly shows that our methods to find vulnerabilities and detect ongoing or successful attacks in critical infrastructure environments are not sufficient. CRISALIS focuses on these two aspects: detection of vulnerabilities and attacks in critical infrastructure environments. We focus on two different, yet interlinked, use cases that are typical for the power grid infrastructure: control systems based on SCADA protocols and the Advanced Metering Infrastructure. CRISALIS leverages the unique characteristics of critical infrastructure environments to produce novel practical mechanisms and techniques for their security assessment and protection. This is achieved by pursuing three main research objectives: (i) providing new methodologies and techniques to secure critical infrastructure systems; (ii) providing new tools to detect intrusions; (iii) developing new, more effective, techniques to analyze infected systems. Particular attention is paid to ensure the practical implementation of these techniques in real-world environments, and to minimize the impact on operations, goals which are attainable thanks to the direct involvement in the process of end users and device manufacturers who provide expertise and realistic test environments to validate the proposed methodologies.

This paper identifies the risks for the functionality and reliability of the grid that arise from the integration of the transport and supply chain. The electrification of transport is a promising option for the transition to a low carbon energy and transport system. But on the short term, the electrification of transport also creates risks. More specifically, when promising technological such as vehicle-to-grid and smart-grids are not yet available on a large scale, the rapid diffusion of electric vehicles and the recharging behaviour of consumers can create risks for grid functioning. In order to assess these risks, this paper present a GIS-based simulation method that assesses electricity demand and supply on the neighbourhood level. The paper combines local level electric vehicle diffusion forecasts, with neighbourhood level data about the grid additional capacity. Application of the model to the Netherlands shows that risks for grid functioning already appear as early as 2015. More specifically, the diffusion of electric vehicles is found to compromise the functioning of the grid on the short term in densely populated areas such as Amsterdam. In these neighbourhoods early and fast adoption of electric vehicles coincides with the presence of an older grid with less additional capacity. The model provides insights for grid operators as well as for policy makers that seek to stimulate the transition to sustainable energy and transport systems, and can be used as a strategic tool to plan (smart) grid investments. © 2014 The Authors.
