Distribution network: PV and PMSG ancillary services

The paper presents the study performed to evaluate the interactions between Distributed Generation and the network during voltage dips. In particular, international grid codes that require Distributed Generation to stay connected during network faults have been considered. In the study a PhotoVoltaic power system (PV) and a typical wind power system based upon a Permanent Magnet Synchronous Generator (PMSG) connected together to a Medium Voltage (MV) distribution network have been simulated. Fault Ride Through (FRT) requirements that provide the inverter should supply a controlled current over q-axis during a balanced voltage dip have been considered.
