Given increases in electricity consumptions, coupled with finite resources and technological advances, ICT-enabled electrical networks such as smart grids are increasingly being deployed by energy companies. One part of smart grids is smart meters, which are digital electrical meters, having the potential to increase energy efficiency in both residential and industrial sectors. However, a chall...

Cloud computing is a new computing paradigm and it is gaining wide popularity due to its benefits including reduced cost, ease of management, and increased reliability. In a cloud computing environment, companies or individuals offload their computing (hardware/software/data) to the cloud, which is supported by the computing infrastructure called datacenters. Datacenters consume large amounts o...

The topic of the presentation is about a work package of our on-going Finnish national research program SGEM (Smart Grids and Energy Markets), where smart grid concept – a low-voltage direct current (LVDC) distribution network is researched. The research is mainly carried out in Lappeenranta University of Technology (LUT). In the LVDC concept, smart grid functionalities, such as smart metering,...

Smart grid is a modern electrical grid technology that improves the efficiency and reliability. The main challenges of smart grids are how to manage different types of front-end intelligent devices such as smart meters and how to process a huge amount of data received from these devices. Cloud computing, a technology that provides computational resources on demands to address these challenges. ...

Future smart grids will consist of legacy systems and new ICT components, which are used to support increased monitoring and control capabilities in the lowand medium-voltage grids. In this article, we present a cybersecurity risk assessment method, which involves two interrelated streams of analyses that can be used to determine the risks associated with an architectural concept of a smart gri...

Worldwide, electrical grids are developing into smart grids. To ensure reliability, robustness and optimized resource usage, these grids will need to rely heavily on modern information and communication technologies. To support the achievement of these goals in communication networks, we evaluated the possibility of using software-defined networking (SDN) infrastructure based on OpenFlow, to pr...

A key element to realize smart grids is an efficient and reliable communication network. Now smart grids could benefit from a multitude of heterogeneous radio access networks for communications independently of positions. The synergic operation of wireless network is a promising technology, which can improve the efficiency of smart grids significantly. In this paper, a new adaptive network sele...

Intelligent electricity grids, or ‘Smart Grids’, are being introduced at a rapid pace. Smart grids allow the management of new distributed power generators such as solar panels and wind turbines, and innovative power consumers such as plug-in hybrid vehicles. One challenge in Smart Grids is to fulfill consumer demands while avoiding infrastructure overloads. Another challenge is to reduce imbal...

Integrating smart solutions into the existing power infrastructure promises to offer attractive capabilities of dynamic monitoring, measuring and even controlling power flows in real time that can help identify losses and trigger appropriate technical and managerial actions to minimize the damage. With the vision of building a Smart India, Government of India’s National Smart Grid Mission (NSGM...

Smart grids play an important role in the modernization and optimization of the existing electrical grid, to accomplish the current European Union Energy and Climate targets. Smart grids require distributed applications to manage the grid more efficiently. The performance of the distributed applications impacts on the communications delay time and on the timely interaction with the devices loca...
