Novel deep supervised ML models with feature selection approach for large-scale utilities and buildings short and medium-term load requirement forecasts.

Accurate energy analyses and forecasts not only impact a nation's energy stability/security and environment but also provide policymakers with a reliable framework for decision-making. The load forecast of buildings and electricity companies for the arrangement of risk/low-cost demand and supply resources that fulfill future government commitments, plans consumer targets, and respond appropriately for stockholders. This study introduces two novels deep supervised machine learning models, including: (i) fit Gaussian Kernel regression model with random feature expansion (RFEM-GKR); and (ii) non-parametric based k-NN (NPK-NNM) models for buildings and the utility companies load demand forecasts with a higher predictive potential, speed, and accuracy. Five-fold cross-validation is used to reduce prediction errors and to improve network generalization. Real-load consumption data from two different locations (utility company and office building) are used to analyze and validate the proposed models. Each location data is further divided into six different feature selection (MFS) states. Each state is composed of various (16, 19, 17, 09, 16, and 13) types of real-time energy consumption and climatic feature variables. The energy consumption behaviors are then analyzed in terms of the feature significance applied with 5 min, 30 min, and 1-h of time-based on short-, and medium-term intervals. Eleven distance metrics used to measure the number of the neighboring object and the number of objective functions of the model network for accuracy. With less computational time, higher precision, and high penetration levels of multiple input feature variables, the method RFEM-GKR is proven superior. Therefore, because of its high accuracy and stability, the proposed model can be a successful tool to predict energy consumption. Image 1 • Two novel RFEM-GKR and NPK-NNM have been proposed for accurate short-and medium-term load forecasting. • Three different 5-min, 30-min and 1-h load forecast intervals were evaluated for two different locations. • The ML models have the ability to handle higher level of uncertainty in the building and load demand data for utilities. • RFEM-GKR shows higher accuracy in the forecasting of short and medium-term load demand. • Concluding results helps users manage energy load planning.
