The paper study the issue of designing power supply systems using innovative approaches based on Smart Grid technologies. The main attention is paid to creating a model of a hybrid power supply system that integrates renewable energy sources (solar panels, wind turbines) and batteries. The main components of smart systems are analyzed, in particular aspects of energy flow management and resource optimization. The development of models and simulations was carried out using modern environments for technical calculations and modeling. The study focuses on environmental sustainability, reducing energy costs and increasing the reliability of power supply. An important place is given to the use of statistical methods for analyzing climate data and predicting the characteristics of renewable energy sources. The proposed model demonstrates the possibilities of integrating traditional and renewable sources into a single intelligent system. The results obtained create the basis for further improvement of smart technologies in the field of power supply.
