From the activity of a group of German researchers comes an interesting novelty for the sector Aeolian: the project "wind on the grid“, Or a“ super wind farm"Formed by many wind farms scattered in the same region or, even, in the same country, interconnected in a single, large, power grid comes alive and begins to demonstrate its enormous potential.
It has been concretely demonstrated, in fact, how through the large-scale grid of the various wind farms, theelectricity can flow smoothly without problems of overloads and risk of interruptions, allowing the network can always be efficient and active, powered continuously, regardless of changes in wind direction and by the presence of the latter in some areas rather than in others. In practice, even if at a certain time and in a certain part of the country the gusts of wind will be unsuitable for turning the rotors, there will always be another connected area capable of guaranteeing the continuity of the electricity grid which will be like this, always active.
During the project also funded by the European Union and started in 2006, the German researchers of the Fraunhofer Institute for Wind Energy and Energy System Technology were able to connect a group of several large wind farms in the same network, present in two distinct countries of the Pensiola Iberica. In fact, five wind farms have been integrated into Portugal, with a total capacity of 204 megawatts and you are in Spain, with a total power of 107 megawatts. According to the researchers, the wind farms present in the Iberian Peninsula could be further integrated, on a large scale, also with the European electricity grid which would therefore be increasingly powered by wind energy. The aim of the project is in fact to cover at least 12% of European energy needs through these plants by the end of 2010. Kurt Roehrig, head of the department at the Kassel headquarters ofIWES, is proud of this integration project, one of the largest of the EU. “Individual wind farms” - said Roehrig- “are subject to large fluctuations in the production of many wind farms. To balance these fluctuations, caused by variations in wind intensity, they can be interconnected into a cluster. This system will reduce costs. In fact, the higher the number of systems installed, the lower the price of energy. The price of electricity produced from wind power is currently seven cents per kilowatt-hour, and by 2025 it should be around four cents. "In the long term - says Roehrig convinced -" wind farms will replace traditional power plants ". The project Wind on the grid it is the result of collaboration between research organizations and industrial groups. To help network operators in capturing, controlling and forecastingwind power, the IWES made available two powerful software created and implemented for the occasion, namely the Wind Farm Cluster Management System (WCMS) and the Wind Power Management System, which made it possible to better evaluate and study the data transmitted in real time in a variety of weather conditions: "We used WCMS - added Roehrig - to connect the wind farms scattered in a cluster, allowing them to be controlled by the command centers of the Portuguese and Spanish users. While the WCMS keeps the frequency and voltage of the power grid constant, thus ensuring safe operation, the Fraunhofer Wind Power Management System uses artificial neural network management software to calculate expected wind energy based on predicted climate models. " The German researchers are negotiating with the Portuguese grid operator, with the aim of integrating their software into the latter's control system. Andrea Marchetti
