GridBox Smart Grid

"GridBox" is a comprehensive Smart Grid concept for the distribution grid. It is based on distributed
devices for measurement and control, communicating data in real-time, constituting a comprehensive
and flexible platform for applications in the distribution grid.
The GridBox concept was developed during two studies, which were supported by the Federal Office
of Energy, as well as partners ewz and BKW. The "GridBox pilot grid" project is a real-world
implementation of the GridBox concept in terms of a "proof of concept" in two field trial regions in the
canton of Bern and in Zurich (voltage level N5 and N7).
Within the project "GridBox pilot network" the technological platform was developed and rolled out by
the two grid operators and operated for one year. Algorithms for grid state estimation, grid stability and
voltage control have been developed and demonstrated in campaigns. In addition, extensive analyzes
of the measurement data were made and profund practical experience in installation and prosumer
interfaces have been made.
