In response to the limitations of traditional meteorological weather typing and considering the scenario-matching degree of optimization algorithms
RIME algorithm convolutional neural network long short term memory attention(RIME-CNN-LSTM-Attention)photovoltaic output combination prediction model based on generalized scene segmentation(GSS) is proposed. Firstly
guided by scientific and typical principles
a generalized scenario segmentation method based on a generalized scenario segmentation indicator is introduced
providing solution ideas for solving the daily weather similarity and coupling problems existing in traditional classification and aggregation methods
effectively supporting the construction of high-precision prediction models. Secondly
a foundational photovoltaic power output prediction model is constructed by combining the temporal feature extraction capabilities of long short-term memory (LSTM) networks with the spatial feature extraction advantages of convolutional neural networks (CNN) and introducing an attention mechanism. This approach enhances the model’s ability to capture critical information and effectively improves the overall accuracy of the predictions. Additionally
considering the nonlinear characteristics of photovoltaic output under conditions of strong uncertainty
an optimization algorithm based on the physical phenomenon of frost ice is introduced
significantly enhancing the optimization algorithm’s adaptability to complex scenarios. Simulation results show that the GSS-based RIME-CNN-LSTM-Attention combination prediction model can effectively improve the accuracy of photovoltaic output predictions
demonstrating high predictive accuracy and practicality in scenarios where photovoltaic output is highly volatile.
