Dedicated spotlights on technical results of the GRID4EU Demo 3 are available via the following downloadable articles:
Iberdrola completed long ago the roll-out of smart meters in Castellón, a city of 200,000 inhabitants in the Mediterranean coast (around 100,000 points of supply). This roll-out offers a unique opportunity to enhance the deployment with other Smart Grids functionalities, and will work as a large experiment lab for the subsequent deployment in all the Spanish territory of Iberdrola.
The new functionalities cover telecommunication, automation, supervision, and in-home consumer equipment for 200 houses. More than 20 Secondary Substations have been the scenario to test improvements such as high availability for MV-BPL, enhanced coupling systems, new protocols, prototypes for LV and MV supervision, smart meters line detection and others. Central control systems have also been improved with new features.
The main objective is to enhance observability and control of the low and medium voltage networks, in connection with a multi-layer solution for smart metering, in order to:
