Local performance of the smart rural grid through the local energy management system

This paper aims to detail and illustrate the operation of the LEMS during the grid-connected and grid-disconnected mode of the Smart Rural Grid (SRG) project. The SRG project is focused on DSO's capabilities to increase the interoperability, resilience, efficiency and robustness of the existing rural distribu­tion network by the utilization of new Smart Grid technologies. This project is founded by the European Union and it is constituted by an eight partners consortium mixing their know-how in a hybrid smart solution; therefore, power electronics, control theory, telecommunications, distribution system operator energy managing, supervisory systems and end-users coexist in a pilot network. This pilot network includes four rural secondary substations up to 200 kVA interconnected by means of medium voltage rural overhead lines in Vallfogona, Catalonia, Spain.
