The present invention is based on the Sandia Voltage Shift (SVS) technique, which includes a small Non-Detection Zone (NDZ) and by an acceptable solution to the tradeoff between the output power quality and the effectiveness of islanding detection. The present invention has the advantage to improve the NDZ and to reduce the anti-islanding detection times. This is due to the exponential-product modification made in the positive feedback to inject current, thereby making the response faster than SVS. Additionally, a self-adaptive gain is considered to achieve a low Total Harmonic Distortion (THD) at different power levels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Exponential active anti-islanding method and device","description":"A device and method based on an active anti-islanding technique for Distributed Power Generator Systems.
