Home energy management system in electrical systems of distributed generation

The global energy transition and the growing demand for energy resources determine the urgency of the problem of household energy consumption management. With the help of general scientific and general logical research methods, as well as the method of description, it is proved that the traditional approach to energy consumption management of households provides for the management of guaranteed energy supply, but in a changing energy system with its inherent dependence of supply on suitable conditions, the problem of energy storage and demand management comes to the fore. It has been established that demand management for electric energy and the integration of households into the energy system are impossible without the implementation of an automated energy management system at home, which is the basic element of building an energy system with integrated distributed energy sources. The main standards of wireless communication of devices are considered, on the basis of which a home energy management system and various configurations with a description of information flows can be implemented. An overview of the main open source systems and ready-made hardware and software solutions has been made. Based on the results of the study, the need to find such a comfortable solution for integrating the energy management system of a house into electric networks is justified, in which optimal control of the energy consumption of a house using solar energy, integrated energy meters, controlled devices, electric vehicles, batteries, a demand management mechanism, capacity redundancy will be achieved, which will help households optimize spending for electricity, and the wider use of distributed energy sources will reduce power outages caused by accidents and ensure the rapid restoration of the power system in critical operating conditions.
