The development of alternative energy and the latest principles of forming power supply systems based on dispersed microgeneration has given rise to the improvement of mobile power plants with several redundant different energy sources. Hybrid mobile power complexes with intelligent control of their operating modes are highly efficient power plants for the construction of microgrids, which can supply both industrial and domestic consumers in the city infrastructure. The paper proposes a modern design of a hybrid mobile power complex developed by the authors to solve the problems of reliable and high-quality power supply to consumers. In addition, the mobile power plant is multifunctional in terms of operating modes and purpose and can be used as a backup power source and a consumer regulator. To improve the energy efficiency of the hybrid mobile power complex, algorithms for intelligent control of the processes of electricity generation and distribution based on logical elements have been developed. The modelling of the operating modes of the hybrid mobile power complex was carried out, the results of which prove the effectiveness of the design and the possibility of implementing an energy-efficient power supply system both autonomously and in parallel with the grid with separate and joint generation of energy sources and storage systems.
