Within the global challenge to increase the energy production from Renewable Energy Sources (RES), a key role is and will be played by those plants connected to the Distribution Network (DN). However, a higher and higher penetration of RES connected at the Low and Medium Voltage grid requires redesigning the procurement of the Ancillary Services (AS) needed by the Transmission System Operator (TSO). In this Thesis a set of Realtime Remote co-simulation is executed with the Politecnico di Bari university, within the Living Grid research project. Firstly, the quality of the comunication between the two research facilities is investigated. A series of Realtime co-simulations with Remote Power Hardware In the Loop (PHIL) is implemented with the following aims: verify the feasability of a LV exible resource dispatchment and verify the stability of the proposed Remote co-simulation.
