Effects of intentional threats to power substation control systems
Power station control and management systems represent key elements for guaranteeing the security of the power grid infrastructure. Intrinsically conceived to support the continuous provision of power in secure conditions, those systems today make intensive use of information and communication systems and are therefore exposed to related accidental and intentional cyber threats. This paper ...

Spectral analysis of a real power network
We present a spectral analysis of a significant part of the Italian bulk power system. Spectral analysis applied to graphs is not a new tool, but analyses of the real world, especially of technological networks, currently are lacking. We show the spectral pattern of a high voltage power network, calculate the ratio between the smallest and largest non–zero Laplacian eigenvalue to check its ...

Knowing power grids and understanding complexity science
Complex networks theory has been well established as a useful framework for studying and analysing structure, dynamics and evolution of many complex systems. Infrastructural and man–made systems like power grids, gas and water networks and the internet, have been also included in this network framework, albeit sometimes ignoring the huge historical body of knowledge surrounding them. Although ...

The evolution of the topology of high-voltage electricity networks
The electricity network represents an example of an evolving complex system. The first local networks contained only a few nodes, but within several decades, they have evolved into a highly connected continental system. The growth of these networks was influenced by various factors such as economic, demographic, political and technological developments. In this paper, we analyse the growth of the ...

Stability of a model of power microgeneration network using the Kuramoto model
Most of critical infrastructures (CIs) depend on the power system. The predictable onset of a microgeneration paradigm (many dispersed small generators of medium-low power) will considerably decrease network stability and thus increase risk of failures and other's infrastructures dependence. In order to study the stability of synchronisation in a power microgeneration scenario, we derive the ...

Demonstration site at Runde, Norway - Case study
In early 2016 a full size Waves4Power system was launched approximately half a Nautical mile south west of the Runde Island. The system is comprised of an eight meter in diameter buoy connected via a dynamic low voltage cable to the collection hub. Here, a transformer increases the voltage to 22 kV before the power is transmitted via a subsea cable to the shore-based power grid. The plan is to ...

Garden Island Microgrid (WA) Project
The Garden Island Microgrid is an integrated renewable microgrid project including a connection to Carnegie’s wave energy site directly offshore from the island. The 2 MW of solar and associated battery system provide clean, reliable energy to Australia’s largest naval base. Customer : Department of Defence Project Partners: Department of Defence, Western Power and the Australian ...

Security, trust, and QoS in next-generation control and communication for large power systems
The present communication architecture supporting control of the electric power grid makes it difficult to use the wealth of data collected at high rates in substations, retarding their use in new applications for controlling the grid. A flexible, real-time data network would make it possible to use these data for many more control and protection applications, potentially increasing the grid's ...

A perspective overview of topological approaches for vulnerability analysis of power transmission grids
Vulnerability analysis is a key issue in power systems since power transmission grids play a crucial role as a critical infrastructure. The power grid structure (number of nodes and lines, their connections, and their physical properties and operational constraints) is one of the main factors to assure power system security. Complex network theory as a promising topological approach for the ...
