AI4PV – Artificial Intelligence for the Operation and Maintenance of PV parks

Solar energy is considered as one of the main carriers leading the energy transition. In a scenario of high penetration of PV, where plants sizes are expected to grow exponentially, it is fundamental to increase plant reliability and performance, while reducing O&M costs. A typical utility-scale PV plant has thousands of PV panels and auxiliary systems, thus early detection of faults is pivotal to avoid production losses over time. Energy production is affected by several factors such as soiling, panel degradation, inverter shutdown. However, most of these faults have the same impact on the power output, making fault detection and classification challenging. The main goal of the AI4PV project is to increase the performance of PV plants by integrating Digital Twins (DT) and Data Analytics of plant signals. This combination is key to perform an automatized Root Cause Analysis (RCA) of faults, providing accurate insights on the status of the different components. AI4PV’s monitoring and fault detection mechanisms articulate over three different layers:

- DT of PV plants’ components for fault detection and diagnosis.

- AI algorithms for RCA and identification of faults and underperformance.

- Decision-aid tool for preventive maintenance and prioritization of actions based on return-on-investment considering O&M costs and policies.


The framework of a digital twin of a PV inverter and their integration with ML algorithm

Digital twins (DT) are a powerful tool that can be applied to several areas of science and industry. Ranging from medicine to engineering, the DT allow one to explore multiple scenarios of a given asset in current or future configurations. Within the AI4PV project, a DT of a PVPP was developed, tackling the operation of the PV modules, inverter, transformer, and other electrical equipment connected to those components. The synthetic data generated by the DT combined with the real data retrieved from the SCADA system can be fed to ML algorithms for pattern recognition to develop fault and failure classification and diagnosis. In this webinar, a brief definition of DTs followed by a discussion about the PV inverter is carried out, finishing with the integration of the synthetic dataset with the classification ML algorithms and the whole DT framework.
