The concept of designing energy-efficient hybrid power plants using Russian components

Justification. Modern research on hybrid power plants is mainly focused on foreign components and solutions, while the issues of creating energy-efficient systems based on a domestic element base remain insufficiently developed, especially taking into account the requirements of import substitution and operation in Russian conditions.The purpose of the study. Development of a design concept for an energy-efficient hybrid power plant based on domestic components with an assessment of their compatibility, efficiency and applicability as part of a parallel hybrid architecture.Methods. A systematic analysis of modern serial and high-performance hybrid power plants of the global market has been carried out in order to identify trends in the development of architectures and energy management systems. The results of virtual and bench tests of the prototype hybrid power plant of the FDR12 racing car were used as an experimental base. Based on them, a digital twin of the system has been developed and verified. Traction electric drive control strategies, thermal modes, energy recovery processes, and the efficiency of power components are investigated. An analysis of domestic components, including an internal combustion engine, a synchronous traction electric motor, power electronics, and a lithium-titanate battery, has been performed in terms of their integration into a single system.Results. The targets for the development of a hybrid power plant have been formed based on an analysis of the global market. A digital twin of the hybrid system has been developed and verified, which makes it possible to evaluate the effectiveness of various control strategies and operating modes. The fundamental compatibility of domestic components in the parallel hybrid circuit, including electrical, mechanical and algorithmic integration, has been established. The effective operating modes of the traction electric drive, energy recovery and thermal control of the system are determined.Conclusion. A design concept for a hybrid power plant has been formed that integrates domestic components into a single energy-efficient architecture adapted to operational conditions. The results obtained form the basis for the subsequent design and serial implementation of hybrid power plants. The limitation of the study is the use of a prototype racing car as an experimental base, as well as the need for further validation of solutions in mass production.
