This study presents a comprehensive comparative analysis of Machine Learning (ML) and Deep Learning (DL) models for predicting Wind Turbine (WT) power output based on environmental variables such as temperature, humidity, wind speed, and wind direction. Along with Artificial Neural Network (ANN), Long Short-Term Memory (LSTM), Recurrent Neural Network (RNN), and Convolutional Neural Network (CNN), the following ML models were looked at: Linear Regression (LR), Support Vector Regressor (SVR), Random Forest (RF), Extra Trees (ET), Adaptive Boosting (AdaBoost), Categorical Boosting (CatBoost), Extreme Gradient Boosting (XGBoost), and Light Gradient Boosting Machine (LightGBM). Using a dataset of 40,000 observations, the models were assessed based on R-squared, Mean Absolute Error (MAE), and Root Mean Square Error (RMSE). ET achieved the highest performance among ML models, with an R-squared value of 0.7231 and a RMSE of 0.1512. Among DL models, ANN demonstrated the best performance, achieving an R-squared value of 0.7248 and a RMSE of 0.1516. The results show that DL models, especially ANN, did slightly better than the best ML models. This means that they are better at modeling non-linear dependencies in multivariate data. Preprocessing techniques, including feature scaling and parameter tuning, improved model performance by enhancing data consistency and optimizing hyperparameters. When compared to previous benchmarks, the performance of both ANN and ET demonstrates significant predictive accuracy gains in WT power output forecasting. This study’s novelty lies in directly comparing a diverse range of ML and DL algorithms while highlighting the potential of advanced computational approaches for renewable energy optimization.

Precise forecasting of solar power output is crucial for integrating renewable energy into power networks, improving efficiency and dependability. This study assesses the efficacy of several Machine Learning (ML) algorithms in predicting solar power generation through a detailed performance comparison. This paper analyzes six algorithms: CatBoost, Gradient Boosting Machines (GBMs), Multilayer Perceptron (MLP) regressor, Support Vector Machines (SVMs), XGBoost, and Random Forest (RF). Using a dataset of 4213 sets of solar power generation data, each model was trained and tested, with performance evaluated based on R-squared (R²) scores for the whole dataset, training set, and test set. Also, this study examined the mean and standard deviation of test set predictions to gauge how consistent each model was. The results showed that RF had the highest overall R² score of 0.940 and a training set score of 0.971. XGBoost demonstrated exceptional performance on the test set, attaining a high R² score of 0.822. CatBoost and GBMs exhibited strong performance, albeit with slightly lower R² values of 0.786 and 0.829, respectively. Although the MLP regressor and SVMs exhibited high training scores, they encountered difficulties in generalizing to unfamiliar data. This paper highlights the effectiveness of combining XGBoost and RF techniques in improving the accuracy of solar power forecasts. The investigation focuses on enhancing the precision and reliability of renewable energy projections through a comprehensive comparison of various contemporary ML techniques.

Optimal planning of integration the Photovoltage Distributed Generation (PV-DG) and DSTATCOM is a crucial task due to the stochastic variations of PV output power and the load demand which are related to solar irradiance variations and the activities of the customers, respectively. In this article, the optimal planning problem of the PV-DG and DSTATCOM system is solved. The proposed model considers the uncertainties of the solar irradiance and the load demand for a multi-objective function, including the cost reduction, the voltage profile, and stability index improvement. Modified Ant Lion Optimizer (MALO) is proposed to enhance the basic ALO searching ability using two strategies. The first strategy is based on Levy Flight Distribution (LFD) to strengthen the exploration of the algorithm and avoid the premature of the basic ALO. In contrast, the second strategy is based on updating the solutions in a spiral orientation to improve the exploitation of the algorithm. The IEEE 69-bus and 118-bus radial distribution systems are used to demonstrate the effectiveness of the proposed method, and the yielded simulations are compared with the basic ALO and other well-known optimization techniques for power loss minimization under deterministic conditions. The simulation results demonstrate that the techno-economic benefits can be increased considerably by optimal inclusion of two PV-DGs and DSTATCOMs compared with a single system.

This study investigated the application of advanced Machine Learning techniques to predict power generation and detect abnormalities in solar Photovoltaic systems. The study conducted a comprehensive assessment of various sophisticated models, including Random Trees, Random Forest, eXtreme Gradient Boosting, Linear Regression, Gradient Boosting (GB), and Categorical Boosting (CatBoost), utilizing a substantial dataset of 97,333 sets. The analysis focused on two fundamental objectives: power prediction and fault identification, both of which are crucial for enhancing the effectiveness and dependability of PV systems. CatBoost and GB models exhibited exceptional performance in power prediction, with the maximum R-squared value of 0.994. Demonstrating a strong correlation with the data and the ability to account for a substantial amount of the variation in power generation. These models outperformed others by providing more accurate and reliable projections, which are crucial for effective solar energy management and planning. CatBoost demonstrated superior performance compared to other approaches in the flaw detection test, attaining the highest performance metrics. The model achieved an accuracy of 0.999743, precision of 0.997171, recall of 0.999291, and an F1 score of 0.998230. The measures illustrated CatBoost’s exceptional ability to precisely identify problems with little errors, confirming it as the most successful model among those evaluated. The exceptional precision and dependability of the CatBoost model in identifying faults highlighted its capacity for continuously monitoring and maintaining solar systems in real-time, consequently augmenting operational efficiency. The study emphasized the significance of choosing suitable models to achieve the highest level of accuracy in predicting and detecting faults, thereby enabling the development of more sustainable and efficient solar energy systems. Subsequent research should prioritize the validation of these models using varied datasets, integration of up-to-date meteorological data, and creation of defect detection methods in real-time to enhance system efficiency.

The results suggest that the inclusion of these models might significantly enhance quality control systems, offering a reliable and efficient method for detecting flaws in solar cells.

This paper examines the perspective of developing a model for a microgrid to optimize the utilization of local clean energy sources for a grid-connected. The suggested model for a microgrid includes clean energy sources employing wind turbines and photovoltaic (PV) systems and diesel generators, the grid. This model is examined with HOMER software. The capacity of the suggested micro-grid model is simulated according to the load profiles and the accessibility of the resources. The basic objectives of energy management are to reduce costs and reduce harmful emissions. The microgrid model with the greatest capacity produced the lowest energy costs, depending on the simulation results, the most significant reduction in CO ₂ emissions, and the greatest percentage of renewable energy.
