Loss of mains detection strategies based on voltage and frequency displacements, passive or active, have been widely applied and conventionally thought for current controlled voltage source inverters. Its effectiveness is questionable when those islanding detection methods are applied on AC voltage droop based inverters. This paper exposes the ineffectiveness of this kind of detection algorithms when are used on AC droop-based inverters type. A power control error based solution, combined with the monitoring of the point of common coupling is proposed as a solution to extend the detection capability. But also, making evident the islanding detection inclusively under the zero power flow concept. A set of simulations supports the analysis and explores the validation scope.
