An Active Anti-Islanding Method Based on Phase-PLL Perturbation [PDF]
IEEE Transactions on Power Electronics, 2011 This paper presents a new active anti-islanding detection method for distributed power generation systems. This method is based on introducing a disturbance at the inverter output and observing the behavior of the voltage at the point of common coupling (PCC), which depends on the impedance connected to the PCC in an islanding situation.
