Conference discusses electric fuses

The event will discuss the topic Future autonomous distribution grids - Fuses in a new environment, which is about the large scale integration of powerful and volatile energy sources but also applications into the distribution grid requests the transition from a static to a dynamic grid.

Local autonomous congestion management is the key for the implementation of such a smart grid. With limited information of voltage and current in the grid, a smart decental controller, installed in the ring main unit, is able to detect all voltage band infringements and overcurrents.

The controller uses suitable grid components, as well as specific demand and generation devices to bring the system back to a stable state. Compared to a conventional static grid the transport capacity is nearly doubled. In the last two years, this smart grid solution has been in operation in two low voltage grid areas in Frankfurt. The transformation of this principle into the medium voltage level is currently in preparation.

With more and more active grid components being integrated into the system, the standardisation process is ongoing. The interaction with the smart market is being analysed. Based on such an active system management scenario, the future roll out of traditional fuses is analysed and recommendations for the further development of fuses are given.
