Utility networks are part of every nation's critical infrastructure, and their protection is now seen as a high priority objective. In this paper, we propose a threat awareness architecture for critical infrastructures, which we believe will raise security awareness and increase resilience in utility networks. We first describe an investigation of trends and threats that may impose security risks...
Recent developments under the term Smart Grid change how users consume electricity and interact with the power grid. Smart metering and energy management are developments that transform the yet passive energy consumer to a participant that is actively involved in the energy market by using variable energy tariffs or by demand-response services. But such functionality demands a platform that integrates...
Renewable energy sources and widespread small-scale power generators change the structure of the power grid, where actual power consumers also temporarily become suppliers. Smart grids require continuous management of complex operations through utility providers, which leads to increasing interconnections and usage of ICT-enabled industrial control systems. Yet, often insufficiently implemented security...
Within this contribution, a first approach of using the European Smart Grid Architecture Model (SGAM) in the context with the NISTIR 7628 is presented. Research in the current state of the art has shown that both models and methodologies have their particular impact, but have not yet been put into a mutual context. Another reason combining these models is the possibility for US smart grid experts...
In intelligent transport systems, connectivity of vehicle is the main feature for improving services to the driver and passengers. In Electric Vehicle domain, permanent connectivity is paramount in order to compensate both the limited range and to achieve an effective grid inclusion enabling the availability of electric energy everywhere anytime. The objective of this paper is to present the risk...
The planned increase of electric energy produced from renewable energy sources in Europe during the time-frame of 2020 to 2050 calls for significant changes in the electric transmission and distribution system. Low loss long distance transmission is needed to bridge the increased distance between generation and load. Demand side participation can be used to balance the increased share of intermittent...
For EC2ND 2011, a special emphasis was given to the protection against attacks in "special environments," such as the ICT component of the smart grid, or the protection against attacks that could cause a large societal impact. To complement the research papers, also a panel was organized to discuss security issues in the smart grid. The members of the panel represent several of the actors...
The practice and future plans of smart grids in Europe are discussed in this paper. Firstly, the features of current power grid in Europe are introduced. Then, the plan of future European power grid with high penetration of renewable energy is introduced. After that, the practice of smart operation of interstate power grid is given. Finally, the most concerned issues and plans for the smart operation...
