The expansion of renewable energies has led to many small decentralised energy producers, such as wind power plants and photovoltaic installations, being set up. This led to a complex system with new challenges such as the varying availability of solar energy and wind energy.

Basic knowledge energy systems

Conversion in energy systems

The efficient conversion of available energy into the respectively most suitable form of energy is an essential prerequisite for modern networked energy system.

Storage in energy systems

Renewable energy systems produce different amounts of energy depending on the available wind power or changing solar radiation. Coverage of the energy demand from evening to morning therefore requires suitable intermediate storage of the surplus energy from the day, if no constant supply of energy is possible, for example from a biogas plant.
