The University of the Basque Country, IBERDROLA (an electricity utility supplying the Basque Country), the enterprises INGETEAM and INDAR and innovative energies company EHN have participated jointly in this research project. The project has put forward an innovative use of wind-sourced energy to control fluctuations on the grid. The research site where measurements were made was the Salajones wind park in Sanguesa (Navarre).
In recent years the electricity utilities have shown much greater interest in achieving uniform distribution of the grid supply system, given that the number of independent sources of power connecting to the grid are increasing all the time: wind parks, solar panels, and so on. Given all these new sources, the power supply level or power profile of the grid constantly rises and falls and, thus, gives rise to grid fluctuations and instability. As a result, the means whereby energy is consumed at source as well as how to confront problems of instability arising from changes in grid load or in its topology are both being investigated. If the solutions to these problems are found, it will be that much easier to stabilise the levels of the electric grid.
This stability provides an improvement in power profile and so in grid safety and security and reduces losses in costs of energy transfer. Moreover, the fact that equipment connected to the grid is using more and more energy has to be taken into account, giving rise to the need to implement complex algorithmic controls. Moreover, in recent decades, research involving regulations for power supply has targeted on-line strategies.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...

Graphene is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today’s silicon-based electronics. Scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) and the University of Duisburg-Essen (UDE), in cooperation with the Max Planck Institute for Polymer Research (MPI-P), have now shown for the first time that graphene can actually convert electronic signals with frequencies in the gigahertz range – which correspond to today’s clock rates – extremely efficiently into signals with several times higher frequency. The researchers present their results in the scientific journal “Nature”.
Graphene – an ultrathin material consisting of a single layer of interlinked carbon atoms – is considered a promising candidate for the nanoelectronics of the...
