Physical Approach to Short-Term Wind Power Prediction

Produktbeschreibung

Triggered by a discussion on the nature of future electricity supplies, wind - ergy utilisation has boomed dramatically, ?rst in the United States of America and Denmark and later in Germany and Spain. Thanks to state subsidies, it has within 15 years overtaken the volume of the classic renewable hydro-power, and today it accountsforabout5%ofelectricitygeneration. Twofactorssetoffthisdevelopment:anawarenessofthelimitedavailabilityof fossilfuelsandtherecognitionthatinthe19thand20thcenturiesthemassiverelease of fossil CO had kicked off a gigantic climate experiment whose results remain 2 unpredictable. The discussion on the side effects of the wind energy boom, such asoccupationoflandandthechallengespresentedbyintegrationintoconventional electricity generation systems, frequently distract attention from the real goals and bene?ts of this technology. These are establishing an energy sector that will, in the shortterm,reduceCO emissionsandtheexploitationof?niteresourcesand,inthe 2 longterm,createanunlimitedsustainableenergysupply. Because fossil reserves are relatively easy to exploit, a system developed that could hardly be more convenient.

Rezensionen

From the reviews: "The book was triggered by the dramatically boomed wind energy utilisation. ... It is a text book for boundary-layer meteorology, flow simulation, time series analyses and modelling of the behaviour of wind farms also. So the models are well described and their application for wind power prediction is demonstrated. ... The book is provided for scientists and engineers mainly. The text is written very clear. It is completed by 89 figures and 13 tables." (K. Schäfer, Meteorologische Zeitschrift, Vol. 16 (3), 2007)
