Invention Description
Detecting faults in photovoltaic (PV) systems is essential for maintaining efficiency and reliability in large-scale solar energy installations. However, traditional methods often struggle to identify complex fault patterns due to the high interdependence between system variables. As PV systems grow in size and complexity, accurately detecting multiple types of faults becomes increasingly challenging. This creates a need for more advanced analytical approaches capable of capturing subtle relationships within PV data.
Researchers at Arizona State University have developed a quantum machine learning-based approach using advanced parameterized quantum circuits and variational quantum classifiers to improve PV fault detection. By leveraging quantum entanglement and multi-qubit interactions, along with higher-order gates such as Toffoli and CNOT, the system captures complex data correlations that classical methods may miss. The framework integrates flexible quantum feature maps with variational quantum classifiers to enable accurate multi-label fault classification. This approach achieves approximately a 10% improvement in detection accuracy compared to prior quantum models. It provides a powerful tool for monitoring and diagnosing faults in large-scale solar arrays.
This technology represents a novel quantum machine learning approach which leverages quantum entanglement and correlation to improve fault classification accuracy in PV arrays.
