Given the rapid growth and development of solar energy in recent years, accurate forecasting output has become one most critical formidable challenges modern power system. This paper introduces an approach for short-term global irradiance forecasting, combining Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN) Artificial Neural Network (ANN) Multiple Linear Regression (MLR) models. The CEEMDAN decomposition is employed to decompose original data series, extracting crucial features forecasting. model's performance evaluated on two distinct sites Algeria, characterized by Mediterranean desert climates. Statistical tests reveal a significant enhancement nRMSE values, approximately 14.09% 7.86% improvements ANN_CEEMDAN model about 17.52% 8.97% enhancements MLR_CEEMDAN model, specifically first hour forecast.

With the rapid development of solar energy plants in recent years, accurate prediction power generation has become an important and challenging problem modern intelligent grid systems. To improve forecasting accuracy generation, effective robust decomposition-integration method for two-channel irradiance is proposed this study, which uses complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN), a Wasserstein generative adversarial network (WGAN), long short-term memory (LSTM). The consists three essential stages. First, output signal divided into several relatively simple subsequences using CEEMDAN method, noticeable frequency differences. Second, high low-frequency are predicted WGAN LSTM models, respectively. Last, values each component integrated to obtain final results. developed model data technology, together advanced machine learning (ML) deep (DL) models identify appropriate dependencies topology. experiments show that compared many traditional methods can produce results under different evaluation criteria. Compared suboptimal model, MAEs, MAPEs, RMSEs four seasons decreased by 3.51%, 6.11%, 2.25%,

Introduction: Smart grid (SG) technologies have a wide range of applications to improve the reliability, economics, and sustainability power systems. Optimizing large-scale energy storage for smart grids is an important topic in optimization. By predicting historical load electricity price system, reasonable optimization scheme can be proposed. Methods: Based on this, this paper proposes prediction model combining convolutional neural network (CNN) gated recurrent unit (GRU) based attention mechanism explore grid. The CNN extract spatial features, GRU effectively solve gradient explosion problem long-term forecasting. Its structure simpler faster than LSTM models with similar accuracy. After CNN-GRU extracts data, features are finally weighted by module performance further. Then, we also compared different forecasting models. Results Discussion: results show that our has better predictive computational power, making contribution developing schemes grids.
