A Hybrid Prediction Model of Photovoltaic Power System Based on AP, Issa-Based Vmd, Clkan and Error Correction

Published: Jan. 1, 2025

The accurate prediction of photovoltaic (PV) power output is crucial for optimal energy management. However, PV generation systems are influenced by various meteorological factors, resulting in the fluctuation and intermittency issues their power. To enhance accuracy power, this study proposes a novel hybrid model, Convolutional Neural Network-Long Short-Term Memory-Kolmogorov-Arnold networks (CLKAN), integrated with Improved Sparrow Search Algorithm (ISSA), Variational Mode Decomposition (VMD), Error Correction (EC). key contributions research as follows: (i) Iterative Chaotic Map Infinite Collapses (ICMIC) method Quantum Rotation Gate (QRG) applied first time to SSA optimization algorithm. This approach improves issue redundant information dispersion sequences due suboptimal VMD hyperparameters. (ii) By leveraging CNN-LSTM input sequence feature extraction, KAN network B-spline basis function innovatively utilized connect CNN-LSTM-KAN model. Experimental analysis conducted on four typical days across different seasons at station Yunnan Province, China, shows that proposed model achieves higher reduced training time. For instance summer, achieved best performance MAE, SMAPE, RMSE, R2 values 0.22 MW, 0.88%, 0.28 99.91%, respectively, demonstrating its superior performance. Furthermore, application CLKAN based AP ISVMD, stations Gansu, highlights model's robustness spatial temporal scales.

An adaptive ensemble framework using multi-source data for day-ahead photovoltaic power forecasting

Journal of Renewable and Sustainable Energy, Journal Year: 2024, Volume and Issue: 16(1)

Published: Jan. 1, 2024

Day-ahead photovoltaic (PV) power forecasting plays a crucial role in market trading and grid dispatching. It has been empirically demonstrated various fields that combining forecasts yields better results than using individual models. In this work, novel adaptive ensemble framework is proposed based on multi-source data. First, incorporating prior information from physical models, three types of high-performance component models are constructed different Second, multi-label classification method utilized to select performing allowing for switching between model combinations depending the weather conditions. Finally, dynamic used update weights its cumulative errors observed recent past. The was evaluated four-year PV dataset 2019 2022. skill (FS) test year (2022) reaches 50.61%. show FS improved by 4.75% compared optimal model. Compared with other state-of-the-art methods, our achieved best performance improving at least 3.94%. study can be widely applied energy fields, such as wind/load forecasting.
