Effectively managing and optimizing energy resources to accommodate population growth while minimizing carbon emissions has become increasingly intricate. A proficient approach this dilemma is accurately predicting usage across diverse sectors. This paper unveils a genetic algorithm (GA)-optimized support vector regression (SVR) model designed (i) predict electricity generation, (ii) consumption in four primary sectors—residential, industrial, commercial, agricultural, (iii) estimate sector-specific emissions. The proposed model's efficacy assessed by calculating the R2 value, mean absolute error (MAE), root squared (RMSE), residual plot. achieved high accuracy with an MAE of 1.18 %, yielded reliable sectoral predictions, reflected values 1.22 % (residential), 4.98 (industrial), 4.40 (commercial), 4.04 (agricultural). residuals exhibited homoscedasticity, value approached one. predicts that 2027, residential sector will consume 55748.66 GWh energy, commercial 14892.49 GWh, industrial 32642.35 agricultural 2288.37 GWh. It been predicted these sectors release 75437.96-billion-gram equivalents.

Insulators installed outdoors are vulnerable to the accumulation of contaminants on their surface, which raise conductivity and increase leakage current until a flashover occurs. To improve reliability electrical power system, it is possible evaluate development fault in relation thus predict whether shutdown may occur. This paper proposes use empirical wavelet transform (EWT) reduce influence non-representative variations combines attention mechanism with long short-term memory (LSTM) recurrent network for prediction. The Optuna framework has been applied hyperparameter optimization, resulting method called optimized EWT-Seq2Seq-LSTM attention. proposed model had 10.17% lower mean square error (MSE) than standard LSTM 5.36% MSE without showing that optimization promising strategy.

Distribution System Operators (DSOs) and Aggregators benefit from novel energy forecasting (EF) approaches. Improved accuracy may make it easier to deal with imbalances between generation consumption. It also helps operations such as Demand Response Management (DRM) in Smart Grid (SG) architectures. For utilities, companies, consumers manage resources effectively educated decisions about consumption, EF is essential. many applications, Energy Load Forecasting (ELF), Generation (EGF), grid stability, accurate crucial. The state of the art examined this literature review, emphasising cutting-edge techniques technologies their significance for industry. gives an overview statistical, Machine Learning (ML)-based, Deep (DL)-based methods ensembles that form basis EF. Various time-series are explored, including sequence-to-sequence, recursive, direct forecasting. Furthermore, evaluation criteria reported, namely, relative absolute metrics Mean Absolute Error (MAE), Root Square (RMSE), Percentage (MAPE), Coefficient Determination (R2), Variation (CVRMSE), well Execution Time (ET), which used gauge prediction accuracy. Finally, overall step-by-step standard methodology often utilised problems presented.

The foundation of natural gas intelligent scheduling is the accurate prediction consumption (NGC). However, because its volatility, this brings difficulties and challenges in accurately predicting NGC. To address problem, an improved model developed combining sparrow search algorithm (ISSA), long short-term memory (LSTM), wavelet transform (WT). First, performance ISSA tested. Second, NGC divided into several high- low-frequency components applying different layers Coilfets', Fejer-Korovkins', Symletss', Haars', Discretes' orders. In addition, LSTM applied to forecast decomposed view one- multi-step, hyper-parameters are optimized by ISSA. At last, final results reconstructed. research indicate that: (1) Comparing other machine algorithms (e.g. fuzzy neural network), convergence speed stability stronger standard deviation mean; (2) better than that forecasting models; (3) single-step superior two-, three-, four- step; (4) computational load proposed highest compared models, accuracy still excellent on extended time series.
