روشی تطبیقی هوشمند برای تشخیص جزیره سازی در سیستم شبکه PV

Photovoltaic (PV) systems can be tied to a utility grid to work more effectively as an alternative energy sources. One of the major issues about grid-tied PV systems is to avoid non-intentional operation in islanding mode. Many methods have been proposed to detect islanding operation of grid-tied PV systems. They have different non-detection zones for different kinds of load. This paper presents an intelligent adaptive method for islanding detection in grid-tied PV system. The simulation and test results prove its effectiveness and superiority.
