摘要：
Islanding of grid-connected photovoltaic (PV) systems can cause a variety of problems and must be prevented. If the real and reactive powers of the load and PV systems are closely matched, islanding detection by passive methods becomes difficult. The active frequency drift method (AFD) enables islanding detection by forcing the frequency of the current in the island to drift up and down. In this paper, proposed islanding detection method which has period of zero current. Simulation results verified that method using PSIM.
