Comparison of Energy Supply Architectures
Conventional AC Grid Architecture
- Unidirectional flow of energy from power plant to consumer (producer-consumer architecture).
- Nearly every electrical device needs a rectifier or a provided rectified voltage.
- Recuperative energy mostly not used and is lost in local braking resistors.
Industrial Smart DC Grid Architecture
- Open energy flow between all devices (prosumer architecture).
- No losses in additional rectifiers of devices.
- Almost complete reuse of recuperative energy within the DC grid.
- Easy integration of energy storage and decentralised renewable energy sources.
