Abstract

The increasing diffusion of embedded generators on distribution systems leads to the idea of managing portions of the network operating in islanded mode for overcoming emergency conditions. To this aim, it becomes essential to have reliable control strategies for the different types of generator and loads. In this paper some issues regarding the dynamic control of frequency and voltage in MV islanded networks supplied by inverter interfaced DGs are investigated. The aim is to identify opportunities and constraints in light of national regulatory provisions on active power reduction and reactive power compensation. Appropriate models for the inverters control have been developed and systematic simulations of a realistic network switching to islanding operation have been performed.
