Detecting Permanently Activated Bypass Diodes in Utility-Scale PV Plant Monitoring Data

Data-driven operation and maintenance (O&M) schemes are needed to secure efficient operation through the full lifetime of a photovoltaic (PV) power plant. In this study, we expand the capabilities of an analytics platform for data-driven O&M by proposing a method for the detection of permane...
