Smart Grid Technologies in Europe: An Overview

The old electricity network infrastructure has proven to be inadequate, with respect to modern challenges such as alternative energy sources, electricity demand and energy saving policies. Moreover, Information and Communication Technologies (ICT) seem to have reached an adequate level of reliability and flexibility in order to support a new concept of electricity network—the smart grid. In this work, we will analyse the state-of-the-art of smart grids, in their technical, management, security, and optimization aspects. We will also provide a brief overview of the regulatory aspects involved in the development of a smart grid, mainly from the viewpoint of the European Unio

The future of Cybersecurity in Italy: Strategic focus area

This volume has been created as a continuation of the previous one, with the aim of outlining a set of focus areas and actions that the Italian Nation research community considers essential. The book touches many aspects of cyber security, ranging from the definition of the infrastructure and controls needed to organize cyberdefence to the actions and technologies to be developed to be better protected, from the identification of the main technologies to be defended to the proposal of a set of horizontal actions for training, awareness raising, and risk management

What Ukraine Taught NATO about Hybrid Warfare

Russia’s invasion of Ukraine in 2022 forced the United States and its NATO partners to be confronted with the impact of hybrid warfare far beyond the battlefield. Targeting Europe’s energy security, Russia’s malign influence campaigns and malicious cyber intrusions are affecting global gas prices, driving up food costs, disrupting supply chains and grids, and testing US and Allied military mobility. This study examines how hybrid warfare is being used by NATO’s adversaries, what vulnerabilities in energy security exist across the Alliance, and what mitigation strategies are available to the member states. Cyberattacks targeting the renewable energy landscape during Europe’s green transition are increasing, making it urgent that new tools are developed to protect these emerging technologies. No less significant are the cyber and information operations targeting energy security in Eastern Europe as it seeks to become independent from Russia. Economic coercion is being used against Western and Central Europe to stop gas from flowing. China’s malign investments in Southern and Mediterranean Europe are enabling Beijing to control several NATO member states’ critical energy infrastructure at a critical moment in the global balance of power. What Ukraine Taught NATO about Hybrid Warfare will be an important reference for NATO officials and US installations operating in the European theater.https://press.armywarcollege.edu/monographs/1952/thumbnail.jp

Akıllı şehirlerdeki kritik altyapıların siber güvenliği

Smart city is a trending topic that many researchers from different disciplines are interested in. Even though it is supposed to be a study field of public administration, it has also technical dimensions which are focused on by researchers from engineering sciences. On the other hand, there is a security dimension of smart cities which has a boundary that includes multidisciplinary contributions. The security of cities has been an essential issue throughout the ages, but with the emergence of smart cities, the development of internet and communication technologies, and as a consequence of interconnection of critical infra structures in the smart cities, a new dimension of security has been emerged as the headline of security studies. This headline is cyber security. This study aims to investigate cyber security issues in smart cities particularly focusing on critical infrastructures and presents a recommendatory model for providing cyber security of critical infrastructures in smart cities.Akıllı şehir birçok farklı alandan araştırmacıların ilgisini çeken popüler bir konudur. Kamu yönetimi alanında bir çalışma alanı olmasına rağmen, mühendislik bilimlerindeki araştırmacılar tarafından odaklanılan teknik boyutlara da sahiptir. Öte yandan, çok disiplinli katkıları içeren bir sınırı olan akıllı şehirlerin bir de güvenlik boyutu vardır. Şehirlerin güvenliği, çağlar boyunca önemli bir mesele olmuştur, ancak akıllı şehirlerin ortaya çıkması, internet ve iletişim teknolojilerinin gelişimi ve akıllı şehirlerdeki kritik alt yapıların sanal ağlarla birbirlerine bağlanması sonucunda, güvenliğin yeni bir boyutu güvenlik çalışmalarının ana başlığı haline gelmiştir. Bu başlık siber güvenliktir. Bu çalışma, akıllı şehirlerde özellikle kritik altyapılara odaklanan siber güvenlik meselelerini sorgulamayı amaçlamakta ve akıllı şehirlerdeki kritikaltyapıların siber güvenliğini sağlamak için öneri niteliğinde bir model ortaya koymaktadır

Power quality and electromagnetic compatibility: special report, session 2

The scope of Session 2 (S2) has been defined as follows by the Session Advisory Group and the Technical Committee: Power Quality (PQ), with the more general concept of electromagnetic compatibility (EMC) and with some related safety problems in electricity distribution systems. Special focus is put on voltage continuity (supply reliability, problem of outages) and voltage quality (voltage level, flicker, unbalance, harmonics). This session will also look at electromagnetic compatibility (mains frequency to 150 kHz), electromagnetic interferences and electric and magnetic fields issues. Also addressed in this session are electrical safety and immunity concerns (lightning issues, step, touch and transferred voltages). The aim of this special report is to present a synthesis of the present concerns in PQ&EMC, based on all selected papers of session 2 and related papers from other sessions, (152 papers in total). The report is divided in the following 4 blocks: Block 1: Electric and Magnetic Fields, EMC, Earthing systems Block 2: Harmonics Block 3: Voltage Variation Block 4: Power Quality Monitoring Two Round Tables will be organised: - Power quality and EMC in the Future Grid (CIGRE/CIRED WG C4.24, RT 13) - Reliability Benchmarking - why we should do it? What should be done in future? (RT 15

The role of communication systems in smart grids: Architectures, technical solutions and research challenges

The purpose of this survey is to present a critical overview of smart grid concepts, with a special focus on the role that communication, networking and middleware technologies will have in the transformation of existing electric power systems into smart grids. First of all we elaborate on the key technological, economical and societal drivers for the development of smart grids. By adopting a data-centric perspective we present a conceptual model of communication systems for smart grids, and we identify functional components, technologies, network topologies and communication services that are needed to support smart grid communications. Then, we introduce the fundamental research challenges in this field including communication reliability and timeliness, QoS support, data management services, and autonomic behaviors. Finally, we discuss the main solutions proposed in the literature for each of them, and we identify possible future research directions

A Taxonomy-based Analysis of Attacks on Industrial Control Systems

Most critical infrastructure depends on industrial control and automation systems to manage their processes. However, industrial control and automation systems were found to have many vulnerabilities owing to their design. They were initially designed to operate as air-gapped systems. However, with the evolution and the expansion of the industry, they are increasingly being targeted by attackers. Thus, preventative methods must be implemented to minimize/ prevent ICSs from being compromised by patching the vulnerabilities and addressing possible attack vectors. In order to prepare to defend against forthcoming attacks on critical infrastructure, it is vital to understand how past attacks have been carried out. This study analyzed and cataloged cases of attacks against ICSs to form a taxonomy that can be used as a tool to analyze the nature of ICS attacks. The taxonomy developed by this study can aide interested parties to determine potential attack vectors an attacker may choose, based on the attributes discussed in the study. Moreover, this paper also serves as a resource for the interested parties to understand ICSs
