The increasing use of distributed energy resources (DER) presents an opportunity for IEC 61850's SCL capabilities to excel. The topology's configuration for information exchange between low and medium-voltage data has been challenging for grid operators. However, a recent research paper highlights the use of IEC 61850's SCL to improve the effectiveness of a topology identification strategy for low-voltage power lines.

Historically, grid operators struggled to monitor the topology of low-voltage distribution networks due to factors such as unclear asset location, variable load usage by multiple users, and monitoring from user devices. In response, the authors of a recent publication developed smart gateways to identify the topology in a power station. Their method enhances the ability to monitor data and network information distribution.

The smart gateway sends a command to the LTU, and if a specific current is detected from the end user, the LTU sends the information to the smart gateway. An algorithm is then used to determine how the LTUs are connected, generating a map of the station's connections.

The proposed strategy leverages a medium-voltage distribution network configuration scheme and clustering analysis to identify unknown regions. This approach enhances accuracy and avoids the wastage of resources. This strategy's application can improve the monitoring of low-voltage distribution networks, ensuring safe electricity consumption.

By participating in our IEC 61850 training programme, engineers will learn the theory behind SCL files and the standard's topology. This is an opportunity to invest in professional development and keep up with the sector's current pressing challenges.
