A Combined Approach for Model-Based PV Power Plant Failure Detection and Diagnostic

Abstract: Photovoltaic (PV) technology allows large-scale investments in a renewable power-generating system at a competitive levelized cost of electricity (LCOE) and with a low environmental impact. Large-scale PV installations operate in a highly competitive market environment where even small performance losses have a high impact on profit margins. Therefore, operation at maximum performance is the key for long-term profitability. This can be achieved by advanced performance monitoring and instant or gradual failure … Show more

“…Additionally, it is essential to the predictive maintenance model to consider the failure probabilities of PV system elements. Gradwohl et al [13] presented a method that combines physical and statistical models for optimal PV plant maintenance. Its prediction of failure through diagnosis has high accuracy, but diagnosis is not a suitable practice for small-scale PV systems.…”
