Based on the results of the work, the requirements for the circuit-technical solution of the TCC were formed, a specific TCC scheme was selected to solve the task. An analytical study of the regulating characteristics of this TCC was carried out, which confirmed its ability to function in the required mode. Compiled computer models of electrical networks with a powerful nodal load and a developed monitoring and control system for its modes based on the selected TCC scheme. On the basis of scientific research, a prototype of an autonomous electrical system with a nodal load has been created, containing asynchronous motors with a power comparable to the grid. Experimental studies carried out with the help of a prototype confirmed the effectiveness of the proposed solution and the means for its implementation. Based on the results of the studies performed, an analytical report was prepared and a positive conclusion was received based on the results of its consideration on the practical significance of the results obtained by DTEK Seti LLC. The main results of the work were published in 1 article in a scientific publication, which is included in the international scientometric base SCOPUS and 1 article in a professional journal.
