Project - RTE
Customer: RTE Context: RTE, the French electricity transmission system operator is in charge of the high voltage grid installation, connection and management onshore and offshore. This includes the connecting of all the marine renewable energy farms being developed in France. Challenge: With the growth of marine renewable energy developments in France with numerous offshore wind and floating ...

10 Facts you didn’t know about Wind Energy
The oldest rotary windmills are considered to have been used regularly in agriculture and other purposes since 2000 B.C. by peoples of what would today be China and the Middle East who already sensed what the German physicist Albert Betz, the father of physics governing modern wind turbines, called The Theory of Wind Energy, presented and published in his book “Wind-Energie” at the ...

Noor II and Noor III eye cost savings from site integration
With similar timeframes and a shared site, the Noor II and Noor III CSP projects in Morocco’s Noor Ouarzazate Solar Complex are expected to gain from multiple synergies during both construction and operations, Badis Derradji, ACWA Power’s managing director for Morocco, told CSP Today. Parallel construction on the two projects is bringing considerable cost benefits, even though they ...

Context–independent centrality measures underestimate the vulnerability of power grids
Power grids vulnerability is a key issue in society. A component failure may trigger cascades of failures across the grid and lead to a large blackout. Within complex network analysis, structural vulnerabilities of power grids have been studied mostly using purely topological approaches, which assumes that flow of power is dictated by shortest paths. However, this fails to capture the real flow ...

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 ...

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 ...
