Idea of the network
The transformation of the German energy supply in the context of the energy turnaround can only be realized through considerable technological innovations. If the classic energy supply is characterized by central generation with a few generators and a large contribution to short-circuit capacity, a supply network with many decentralized, regenerative feed-in points is now being created.
As a result, the topology of the supply networks changes comprehensively. In most cases, regenerative energy generators feed into the supply network via inverters. Due to the increasing number of decentralized generation plants and the increasing reduction of the short-circuit power, the supply network is becoming more and more susceptible to instabilities.
In addition, the consumer side has also changed very much. Energy-efficient drives are coupled to the supply network by means of converters. As a result, the supply network is burdened with higher frequency components (harmonics) in the mains currents. This, in conjunction with the decentralized feed, further increases the risk of instability.
Based on this, the partners of the cooperation network "netAKTOR" found their way to contribute to the improvement of the quality of electrical energy with new approaches and innovative product ideas.
