Kozlov S. Improving the efficiency of electrical network facilities through the use of Smart Grid

The thesis on Candidate Degree in Technical Sciences: Specialty 05.14.02 – power plants, networks and systems. – National Technical University «Kharkov Polytechnic Institute», Kharkov, 2021. The thesis is devoted to the development and improvement of methods of high power objects with high duty cycle in power supply systems as a part of Smart Grid control system. The analysis of the efficiency of the power supply system of the radio engineering research complex of the Institute of the Ionosphere, which made it possible to determine the possible factors and modes of operation, contributing to the deterioration of the quality of electrical energy from the consumer. The results of energy consumption modes analysis of Institute of Ionosphere incoherent scattering complex are presented. The work of the Institute of the Ionosphere executive devices is modeled. Simulation results showed that experimentally obtained current-voltage characteristics coincided with the current-voltage characteristics of the constructed model. The simulation results allowed to formulate tasks of voltage converters and PWM controller proper usage.
