Renewable energies


Sensible integration of renewable energies


The use of renewable energies in the mix of electricity is one of the central challenges for energy providers. While renewable sources provide better ecological balance, the decentralised and irregular power supply jeopardises network stability.


Ideal integration of renewable energies requires real-time control over these generators. This ensures that the energy from sources such as wind power and photovoltaic systems can be optimally used by consumers. Monitoring in real time enables immediate responses to acute events in the network and regulation of the network load.


Monitoring and controlling renewable energy systems


By using the existing power line, devolo's Powerline communication makes it possible to efficiently set up a comprehensive monitoring system in the smart grid. In order to accomplish this, the current production and status data of the renewable energy plants are sent to the next transformer station via the mains supply using a Powerline modem. This makes it possible to monitor the production output of the renewable energy plants in real time and to regulate it as needed.



Smart grid communication for efficient e-mobility


E-mobility continues to gain speed in Europe. Many automotive manufacturers now offer an attractive portfolio of electric vehicles, allowing them to reach a new target group. At the same time, a more tightly knit network of charging stations is emerging. However, this can jeopardise network stability, especially due to the large amounts of energy drawn by electric cars and the strong fluctuations that result.


The smart energy network relies on comprehensive communication to integrate the charging stations in the best possible way. The IP-based data connection to the smart grid ensures continuous measurement and control. This also enables load compensation by interconnecting charging stations. Furthermore, in future the vehicles connected to the smart grid are expected to serve as batteries for storing extra energy as needed.


devolo offers a comprehensive communication solution


Data communication in real time is required to make the charging station units fit for the smart grid. For this purpose, devolo is utilising G3-PLC technology as well as broadband Powerline technology to provide an efficient communication solution that can be easily integrated into charging stations even after they are built. Powerline communication connects the charging stations to each other and enables an efficient connection to the grid control centre.


Additional services and billing models can be implemented using vehicle-to-grid communication. The Green PHY modules enable devolo to provide an innovative connection, which has now become a global standard in charging station communication. The data connection for this is established via Powerline with the charging connection between station and electric vehicle. This principle enables reliable authentication and comprehensive communication for the charging process. At the same time, billing models and even new services can be integrated.
