Cyber security is becoming more and more relevant with the advent of large-scale systems made of independent and autonomous constituent systems that interoperate to achieve complex goals. To ensure security of cyberphysical systems, it is important to analyze identified threats and their possible consequences. In case of smart grids as an example of a complex system, threats can result in power...

In this paper, we present a distributed incremental data aggregation approach, in which data aggregation is performed at all smart metres involved in routing the data from the source metre to the collector unit. With a carefully constructed aggregation tree, the aggregation route covers the entire local neighbourhood or any arbitrary set of designated nodes with minimum overhead. To protect use...

As expectations have risen about the deployment of smart grids, it is important to investigate the diffusion process of smart equipment such as smart meters, photovoltaic generation, and electric/hybrid vehicles. However, since the revealed preference data have not been accumulated for smart equipment diffusion, this paper conducts a conjoint analysis to examine consumers’ stated preferences on...

The smart grid is the emerging energy system wherein the application of information technology, tools and techniques that make the grid run more efficiently. It possesses demand response capacity to help balance electrical consumption with supply. The challenges and opportunities of emerging and future smart grids can be addressed by cloud computing. To focus on these requirements, we provide a...

This paper present a short survey about recent trends on the arising field of big data. After a definition and explanation of ”Big Data” and a discussion why data sizes increase, appropriate methods to solve big data problems are introduced. In addition, recent applications and future potentials in smart buildings and smart grids are discussed.

This is a summary of the workshop that was held as part of the ICT4S conference with a focus on the topic of social practices and smart grids. Here we present an overview of the five invited paper contributions to the workshop, as well as a summary of the plenary discussion, and our final conclusions. Keywords—sustainability; ICT; social practice theory; smart grid; design

As much as possible, it is important that the smart grid is secure from cyber-attacks. A vital part of ensuring the security of smart grids is to perform a cybersecurity risk assessment that methodically examines the impact and likelihood of cyber-attacks. Based on the outcomes of a risk assessment, security requirements and controls can be determined that inform architectural choices and addre...

In a smart grid, the power service provider enables the expected power generation amount to be measured according to current power consumption, thus stabilizing the power system. However, the data transmitted over smart grids are not protected, and then suffer from several types of security threats and attacks. Thus, a robust and efficient authentication protocol should be provided to strength ...

This paper presents a solution to the Smart Grid case at the Transformation Tool Contest (TTC) 2017 using the .NET Modeling Framework (NMF). The goal of this case was to create incremental views of multiple models relevant in the area of smart grids. Our solution uses the incremental model transformation language NMF Synchronizations and the underlying incrementalization system NMF Expressions.
