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