| Popis: | The large increase of renewable distributed generation envisaged in the next future is yielding multiple concerns to the Transmission System Operators (TSOs). In particular, the connection requests to the EHV – HV network have to be appropriately included in planning studies, considering a rate of concretization of renewable generation initiatives and RES penetration targets in order to account for energy policies. Furthermore, the progressive decommissioning of thermal power plants in the medium/long term introduces additional complexities for both network planning and operation. In this paper, a real case study of the Italian power system is analyzed in the presence of HV operation islands (open loops at double-busbar substations) in static regime during critical contingencies, in a future energy scenario. The identified network reinforcements allow to alleviate the overloads and to improve the system performances. |
