The authors present the development of a consistent modeling and simulation approaches to correctly describe the realistic behavior of wind turbines. The Hybrid Engineering allows simulation and optimization of the performance of mechanical systems for structural integrity, noise and vibration, acoustics, system dynamics and durability, from the initial concept to the complete modeling and simulation of components and the full wind turbine.

The paper proposes a solution of UPQC (Unified Power Quality Conditioner) type to compensate the voltage variations and to provide an actually constant voltage at the terminals of the users with sensitive receivers. The experimental study performed for the developed installation emphasized good response characteristics both in normal and disturbed operating conditions.

Der Umstieg auf Erneuerbare Energien sowie der grosse Erneuerungs- und Ausbaubedarf bei der Produktion und Übertragung lassen einen grundlegenden Umbau des Elektrizitätssystems erwarten. Die Akademien der Wissenschaften Schweiz begrüssen, dass der Bund einen klaren Rahmen für die Energiepolitik der nächsten Jahre schaffen will. Sie unterstützen grundsätzlich die in der neuen Energiepolitik enthaltene Ausrichtung, Energie effizienter zu nutzen und die erneuerbare Stromproduktion auszubauen. Ein weiteres wichtiges Ziel ist die Integration der schweizerischen Stromversorgung in den europäischen Markt.

In der Schrift erörtern die Autoren die prinzipiellen Möglichkeiten zur Förderung des erneuerbaren Stroms und analysieren diese in knapper Darstellung. Alle vier untersuchten Förderinstrumente (Einspeisevergütung, Bonusmodell, Quotenregelung und Ausschreibungen) zeigen dabei Stärken, aber auch Schwächen und es gibt keine einfache Regel für die Wahl eines solchen Instrumentes. Es zeigt sich aber doch, dass – eine weitsichtig planende Politik vorausgesetzt – bei längerfristig stabilen Fördermassnahmen die grossen Ziele für 2030 erreichbar sein sollte
