Energy Storage Systems

Photovoltaic systems, fuel cells, batteries and capacitors deliver DC current.
Enhanced energy efficiency
- Use of braking energy within the DC link
- Lower conversion losses in energy storage systems and renewable energies
Integration of various energy storage technologies (e. g. batteries, capacitors, flywheels).
Coupling and control of several distributed energy storage units and feeders based on droop control without additional communication devices.
Use of a common energy storage by distributed loads in a DC load sector.
Combined use cases of energy storage systems
- Reduced peak loads
- Increased renewable self-consumption
- Enhanced security of supply and reduced downtime (uninterruptible power supply)
- Islanding due to swift disconnection from the AC grid
