Energie-Frage der Woche: Was macht ein Stromnetz intelligent?

Vom Kraftwerk bis zur Steckdose gewährleistet ein engmaschiges und komplexes Leitungsnetz von etwa 1,7 Millionen Kilometern Länge die Stromversorgung in Deutschland. Über Jahrzehnte gewachsen, gewartet und zaghaft ausgebaut, hat sich lange kaum jemand über das Zusammenspiel von Generator und Verbraucher, Stromfrequenz und Hochspannungen, Umspannstation und Transformator Gedanken gemacht. Nun, mit dem steigenden Anteil an regenerativ erzeugtem Strom, steht immer wieder der Begriff des "Smart Grid", des intelligenten Stromnetzes, im Raum. War (und ist) denn unser bestehendes Stromnetz so "dumm"? read more

Energy question of the week: What makes a power grid intelligent?

A closely-interconnected grid of power lines and wires 1.7 million kilometres in length and running from power stations to wall sockets delivers a reliable power supply throughout Germany. It has evolved and been maintained over decades, extended in leaps and bounds, and virtually no-one gives any real thought to the interplay between generator and consumer, power frequency and high voltages, sub-stations and transformers. Now, in response to the rising proportion of electricity generated from renewable sources, the term Smart Grid (the 'intelligent' power grid) is now coming into common parlance. Was, and is, our existing power grid really so 'dumb'? read more
