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.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
