Grid control / Monitoring
The amount of electricity from renewable energy sources from decentralised generators has been continuously growing for years. This presents network operators with significant challenges because the power being fed in is not continuously supplied as is the case for large-scale power plants. Sun and wind conditions become critical factors for network utilisation. In addition, the low-voltage level is not designed for these kinds of massive fluctuations, which can cause voltage range violations, power flow reversals, and overloads.
Adapting transformer stations and lines to the new load situation is not economical because the peaks in the energy network occur only briefly. Smart grid control is preferred for this reason. It relies on continuous monitoring of the low-voltage level for efficient generation and consumption management. Networking of state-of-the-art measuring and control technology prevents overload situations and enables the integration of future network components such as energy accumulators and e-mobility.
The core advantage of using IP-based G3-PLC is that the existing line network interconnects all relevant points of the smart grid at the low-voltage level. Consequently, G3-PLC technology enables direct communication between all sensors and actuators.
Successful field tests and deployments by major energy providers confirm the performance and efficiency of G3-PLC technology. Direct compatibility is ensured by extensive co-operation with the developers and manufacturers of monitoring software for energy suppliers.
