Smart grids will be regarded as a dual compound network composed of power network and cyber network, called Cyber-power System (CPS). Studying the cyberpower relationship, especially the effects of cyber on the whole system, is of theoretical and engineering importance. In this paper, CPS studies were reviewed first, and then a method based on Inclusion-exclusion theory was proposed, which made...

The concept of the smart grid has been gaining more and more attention worldwide since it was proposed by the U.S. Electric Power Research Institute in 2001. Recently, it has been propelled again by the promotion of low carbon economies in developing countries. To satisfy the exponential increase in electricity demand and alleviate environmental degradation caused by fossil fuel-based power gen...

Electricity grids are evolving to “smart grids”. Smart grids employ communication of supply and demand between participants of the grid to achieve better efficiency, availability, resilience, etc. than traditional grids. Consumer households are connected to the smart grid using smart metering and demand response. Smart metering communicates the household’s electricity consumption at high resolu...

Growing energy demands and the increased use of renewal energies have changed the landscape of power networks leading to new challenges. Smart Grids have emerged to cope with these challenges by facilitating the integration of traditional and renewable energy resources in distributed, open, and self-managed ways. Innovative models are needed to design energy infrastructures that can enable self...

The project “Reference Architecture for Secure Smart Grids Austria” (RASSA) is developing a foundation for secure, interoperable architecture components dedicated for future smart grids in Austria. A key feature of this blueprint is its tool supported model driven design approach, enabling users to estimate the risk of components introduced into the models as a decision base for a deeper threat...

Smart grids leverage modern information and communication technology to offer new perspectives to electricity consumers, producers, and distributors. However, these new possibilities also increase the complexity of the grid and make it more prone to failures. Moreover, new advanced features like remotely disconnecting meters create new vulnerabilities and make smart grids an attractive target f...

The idea of Smart Grid has started to evolve more rapidly with the enhancement in Communication Technologies. Two way communication is a key aspect in realizing Smart Grids and is easily possible with the help of modern day advancements in both wired and wireless communication technologies. This paper discusses some of the major communication technologies which include IEEE specified ZigBee, Wi...

Smart grids consist of millions of automated electronic meters that will be installed in electricity distribution networks and connected to servers that will manage grid supervision, billing and customer services. World sustainability regarding energy management will definitely rely on such grids, so smart grids need also to be sustainable themselves. This sustainability depends on several rese...

Energy management is, nowadays, a subject of uttermost importance. Indeed, we are facing several problems like petroleum reserve depletion or earth global warming. Smart Grids, a new type of electrical grid which try to intelligently manage its components, are a possible answer to these issues. Multi-Agent Systems (MAS) are a good candidate for modelling and managing Smart Grids. In this contex...

The development of future electricity Smart Grids requires experts from different areas (such as, electrical engineering, ICT, or industrial automation) and organisations to share knowledge with each other. This work addresses such a complex task by developing a structured approach and tool support that facilitate exchange of Smart Grid requirements and architectures within and among organisati...
