Dynamic equivalent modelling of active distribution networks for TSO-DSO interactions

This paper focuses on the development of equivalent models able to represent the dynamical behavior of active distribution networks. The availability of these models is becoming of fundamental importance for allowing the interoperability between the transmission and distribution system operators. This is due to the large deployment of distributed generation, which is leading distribution networks from playing a passive to an active role into the modern power system. The present paper proposes an equivalent model identification technique for representing the dynamics of a given active distribution network. A detailed model of the Cigre Benchmark Medium Voltage (MV) Distribution Network is implemented in order to validate the proposed equivalent modelling technique.
