Anti-islanding is a key component of solar inverters, ensuring that solar module manufacturers offer products that meet stringent safety requirements. Solar inverters equipped with anti-islanding technology fall into several categories: 1. Central Inverters: Central inverters are common in large-scale solar projects.
6.1. Frequency shift method The typical frequency shift method is active frequency drift (AFD) method, which is easily implemented in PV inverter with a microprocessor-based controller ( Ropp et al., 1999 ). This method makes the PV output current to be slightly distorted in order to detect islanding shown as Fig. 5.
1. Passive Detection: Passive detection is the simplest method of anti-islanding. The inverter constantly monitors voltage and frequency; any significant fluctuations indicate a grid failure, prompting the inverter to disconnect immediately. However, passive detection alone may not always be effective. 2.
As an example, there is an anti-islanding method for multiple PV inverter operation using the fixed inter-harmonic current injection ( Nishimura et al., 2001 ). This AIM uses different inter-harmonic currents for the multiple PV inverters, respectively, like 2.1th harmonic, 2.2th harmonic, etc.
