Recent Advancements

Recent research focuses on improving detection accuracy and speed:

• AI and Machine Learning: Techniques like deep convolutional generative adversarial networks (DCGAN) enhance detection reliability across different system conditions (IEEE Xplore).
• Spectral Analysis: Low-frequency spectral analysis and mathematical morphology filters improve fault detection in complex PV systems (ScienceDirect).
• IEC Standard 63027: This complements UL 1699B by addressing weaknesses in earlier standards, ensuring more realistic testing conditions (Fraunhofer ISE).
