Endesa now has 52 digitised transformation centres in the Cartuja Science and Technology Park (PCT Cartuja) for the #eCitySevilla project, thanks to the incorporation of control and metering elements, which has enabled it to reach 85% of the target for the deployment of elements to form a smart grid by 2022.

For the development of this technology in the digitalisation networks, the LARS (Localisation of Malfunctions and Supply Restoration) system is used. This is an automatic system that works as a virtual operator in the event of a fault, carrying out the necessary grid manoeuvres from the same Control Centre system – just as human operators would do – to isolate incidents and restore supply in less than three minutes. This system is also responsible for managing the remote controls at the transformer substations, which enable remote control of the networks.

Endesa is also working to integrate historical incident data, error rates, street work maps and weather forecasts, among other information, so that the LARS system can determine more precisely where on the line the incident has occurred. By using big data and artificial intelligence techniques to process all this information – for example, where lightning has struck, where street works are being carried out that may affect a cable – the chances of determining the source of the incident more quickly increase significantly.

This advance forms part of the milestones of the Energy working group, led by Endesa, whose most basic objective is to achieve a decarbonised island, with a 100% renewable energy supply and distributed generation. Since the start-up of the project, the work of this group has focused on managing the renewable generation projects to be installed in the PCT Cartuja, the constitution of an energy community made up of the main buildings in the Park and the deployment of the elements that will form part of the smart grid on which this new city model will be based.
