clamped2 Islanding Detection Methods Whether anti-islanding or utilizing islanding, islanding detection methods are always required for a PV integrated system. This section describes the current most popular international islanding detection standards, i.e. IEEE Std. 1547, and its main detection methods. 2.1 Islanding Detection Standards [29] The IEEE Std. 1547 is applicable to a DG-unit with a rated power of less than 10MVA and connected to the primary or secondary distribution system. As the world’s dominant standard for islanding detection, it is adopted by many of power utilities and inverter manufacturers. The IEEE Std. 1547-2003 states that an island shall be detected
