The article describes possible heterogeneities of electrical networks that may be caused by the integration of renewable energy sources into the power system. An assessment of new challenges and problems associated with this process is made. It is noted that solving problems in the process of integrating renewable energy sources into the power system is associated with overcoming the heterogeneity of electrical networks, which significantly affects the operating parameters. To ensure the stability of the power system, it is necessary to perform a multifactor analysis and assess the impact of the introduction of renewable generation from both technical and technological, innovative and political sides. It has been established that the main heterogeneities of electrical networks with renewable sources include geographical, operational, structural, functional and temporal heterogeneity. Each of the heterogeneities has an impact on the efficiency and reliability of power supply. Ways and tools for overcoming various types of heterogeneity in electrical networks are proposed. It is emphasized that a significant contribution to leveling heterogeneity should be provided by smart grid technologies, which, based on the use of real-time data and advanced analytics, will ensure optimal energy dispatching at all nominal voltage levels, especially at the medium and low voltage levels of distributed energy resources and microgrids.
