The framework begins with the calculation of PV costs using the Levelized Cost of Electricity (LCOE) method, continues with predicting PV cost trends through learning curves, and is completed by benchmarking PV costs against electricity prices. Our findings reveal that most current PV cost calculations for grid parity primarily rely on the LCOE method, which can be enhanced by incorporating modifications for integration costs, revenues, PV performance metrics, regional-specific characteristics, and uncertainties. Moreover, learning curve models used to predict PV cost trends can be refined by tailoring learning rates and model formulations to reflect specific stages of technological development and regional differences.

In this study, the proposed VMD-MI-LSTM neural network is employed to forecast mooring line tension under typhoon conditions over short periods. The platform model utilized in this research is the 5-MW Braceless semisubmersible platform, with the transient wind fields of Typhoon Hagibis serving as the research scenarios. Through fully coupled simulations, the tension of mooring lines under typhoon conditions is computed. Using wave height time series and typhoon wind speed as input data and mooring line tension data as output, a dataset is constructed. The optimal model parameters are determined through exploration of the hyperparameter space to develop the multi-input long short-term memory (MI-LSTM) mooring line tension prediction model. An analysis of the prediction results for mooring line #1 is conducted. Given the similarity of environmental conditions across different platform mooring lines, the model's universality is evaluated by predicting mooring line #1 and comparing it with the VMD-MI-LSTM model. This comparison highlights the optimization effect of the VMD variational mode decomposition method. This study provides short-term predictions of mooring line tension under typhoon conditions.

Hence, this work provides an overview of the most used thermal models for installation solutions (free-standing, roof-mounted, floating, etc.) utilizing both mono and bifacial module technology. The provided analysis is focused on evaluating the different responses of the thermal models that can be used for the same configuration and technology. A sensitive comparative analysis of the various thermal models is provided to assess their response to the climatic parameters as an input to the thermal model. The analysis revealed that for monofacial thermal models, Ross models underestimate the cell temperature at any radiation intensity, while the Faiman model using PVsyst coefficients generates the highest overestimated cell temperature among the examined models. It can be seen that the effect of wind speed reduces for a velocity higher than 10 m/s. As for the bifacial PV module, it can be noticed that the Sandia model using Bifacial optimized coefficients is very sensitive to the back surface radiation as it tends to overestimate relative to the Faiman model.
