Melnychuk H. Development of methods for analysis of stationary modes of operation of electrotechnical Smart-complexes.

In the dissertation work the actual scientific problem which consists in development of analytical methods of the analysis of stationary modes of electrotechnical Smart-complexes for the decentralized power supply is solved. In the dissertation work the modern tendencies of development of new technologies of local power supply, including electrotechnical Smart-complexes, the basic principles of their modeling are carried out, analytical expressions of images and originals of voltages and currents are received. The methodology of analysis of electromagnetic processes in systems with periodically (cyclically) changing parameters of generators and loads using the method of separate components is developed, analytical expressions for calculation of integral characteristics are received, the possibilities of application of the received analytical expressions in case of periodic conductive disturbances of various form are carried out. The algorithm of electrotechnical inspection (energy audit) of electrotechnical complexes by use of the offered methodology of the analysis of the established modes and the generalized algorithm of calculation of electromagnetic processes in electrotechnical Smart-complexes is offered, and also the concept of construction and modernization, including electro-complexes for Smart cities. The experience was used in the educational process at the Department of Power Supply of the Institute of Energy Conservation and Energy Management of the National Technical University of Ukraine «Kyiv Polytechnic Institute of Igor Sikorsky». Keywords: electrotechnical complexes, local power supply systems, intelligent power systems, operator method of analysis, method of separated components, Smart Grid, Microgrid, Smart City.
