The paper investigates steady state and transient impact of Distributed Synchronous Generators (DSG) on a real Italian distribution network. Before connecting or allowing the connection of DSG, the worst operating scenarios have to be analyzed to guarantee that the network voltages remain within allowed ranges. A voltage profile variation and steady state voltage regulation are analyzed, therefore following connection of DSG. Transient analysis is also performed in order to analyze the impact of DSG on stability and protection system. Further, the islanding operating mode of the network is considered having in mind that the DSG could provide additional to the load in the absence of the main power supply. In particular, in the event of a supply outage, the temporary islanding operation of DSG might improve the continuity of service and such contribute to the overall quality of electricity supply to the customers.

Abstract
The paper investigates steady state and transient impact of Distributed Synchronous Generators (DSG) on a real Italian distribution network. Before connecting or allowing the connection of DSG, the worst operating scenarios have to be analyzed to guarantee that the network voltages remain within allowed ranges. A voltage profile variation and steady state voltage regulation are analyzed, therefore following connection of DSG. Transient analysis is also performed in order to analyze the impact of DSG on stability and protection system. Further, the islanding operating mode of the network is considered having in mind that the DSG could provide additional to the load in the absence of the main power supply. In particular, in the event of a supply outage, the temporary islanding operation of DSG might improve the continuity of service and such contribute to the overall quality of electricity supply to the customers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
