Energy storage systems are one of the key technologies for the energy turnaround. With their help, the fluctuating supply of electricity based on photovoltaics and wind power can be stored until the time of consumption. At Karlsruhe Institute of Technology (KIT), several pilot plants of solar cells, small wind power plants, lithium-ion batteries and power electronics are under construction to demonstrate how load peaks in the grid can be balanced and what regenerative power supply by an isolated network may look like in the future.
KIT’s Competence E project is presently developing several pilot systems consisting of photovoltaics and wind power plants coupled to a lithium-ion battery. It will have a capacity of 50 kW.
After first functional tests, concrete application systems of variable power will be produced in cooperation with industry.
In spite of the high costs of lithium-ion batteries, this technology may be worthwhile today already, in particular in regions that do not have any stable grids. A photovoltaics system with a coupled lithium-ion battery can be applied profitably, if appropriate system design and load profile are chosen.
