Abstract

For pt.I see ibid., vol.4, no.3, p.436-45 (1989). The methods and models developed in pt.I to study the problem of islanding are extended to study systems containing multiple inverters. The key issues addressed are whether multiple power conditioning systems (PCSs) are more prone to islanding and whether the destabilized feedback used in PCSs such as the APCC and Teslaco can prevent islanding even in the presence of other PCSs in the island. It is shown that islanding can be virtually eliminated through the use of destabilized feedback controls such as the ones available on some commercial units
