Too much wind energy: electricity network operators are preparing for the storm. Spiegel online - 12 Dec 2014
http://www.spiegel.de/wirtschaft/service/windstrom-sturm-billie-laesst-produktion-steigen-a-1008101.html (slightly improved electronically generated rough translation) Generation of electricity in Germany will rise sharply due to the expected storm front "Billie". The transmission system operator Tennet expects a record 28,000 megawatts of wind energy feeding into the German electricity grid. This is equivalent to the capacity of 28 smaller nuclear power plants and is three times the average of power generation by wind turbines. This high feeding brings the power grids to their limits. Tennet, in whose service area the largest share of renewable energy is fed, has prepared extensive measures to ensure that the network does not collapse. Options include so-called redispatch measures: If a power line is already too busy due to devices connected to it, conventional power plants are regulated down for a while. At times, likely on Friday, about 20 conventional power plants are used simultaneously for such redispatch measures, Tennet says. The network operator also assumes that occasionally the capacity of wind turbines has to be restricted to prevent transportation bottlenecks. There are exact schematics to avoid that too many conventional power plants are restricted simultaneously and a sudden gap in coverage occurs. "The scale of the proposed measures shows that the network situation is very tense," said Tennet's CEO Keussen. The infrastructure needs to be urgently developed so that increasing amounts of electricity from renewable energy sources can be fed and transported without interference. _______________________________________________ pen-l mailing list [email protected] https://lists.csuchico.edu/mailman/listinfo/pen-l
