Das CBL2 bietet drei analoge Eing{\"a}nge, die immerhin mit 10 Bit Aufl{\"o}sung und bis zu einer Frequenz von 50 kHz arbeiten. Weiterhin besitzt das CBL2 eine Buchse f{\"u}r angeblich nur einen digitalen Ein- bzw. Ausgang. An diesem Eingang wird standardm{\"a}ßig haupts{\"a}chlich der Bewegungssensor CBR betrieben.

Contradictory to fossil fuel power plants, energy production of wind and photovoltaic (PV) energy is fluctuating. Although predictions have significantly improved, an outage of multi-MW offshore wind farms poses a challenging problem. One solution could be the integration of storage systems in the grid. After a short overview, this paper focuses on two exemplary battery storage systems, including the required power electronics. The grid integration, as well as the optimal usage of volatile energy reserves, is presented for a 5- kW PV system for home application, as well as for a 100- MW medium-voltage system, intended for wind farm usage. The efficiency and cost of topologies are investigated as a key parameter for large-scale integration of renewable power at medium- and low-voltage.}, language = {en} }
