Random forest based intelligent fault diagnosis for PV arrays using array voltage and string currents

TL;DR: The comparison results indicate that the generalization performance of the proposed RF based model is better than the one of the decision tree based model, therefore, the proposed optimal RF based method is an effective and efficient alternative to detect and classify the faults of PV arrays.

Differential evolution random forecast classifier-based photovoltaic array fault diagnosis method

TL;DR: In this paper, a differential evolution random forecast classifier-based photovoltaic array fault diagnosis method was proposed, which comprises the steps of first collecting the voltages under various working conditions, and performing identification on different working conditions by different identifiers; secondly, determining a quantity range of decision trees in a random forest model by adopting an out-of-bag data-based classification misjudgment rate mean value; thirdly, performing global optimization on the quantity ranges of the decision trees by utilizing a differential evolutionary algorithm to obtain an optimal decision tree quantity value; fourthly,
