Presented by the National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute".

A series of the works consists of 3 monographs, 49 scientific articlesand 4 patents, published within8 years.

The basis of highefficiency control of the urban electric transport power supply system as distributed system is created.

A number of fundamental results were obtained whilesolving the problems of improving the urban electric transport efficiency, namely: 1) the means for improving the maneuver characteristics of electric transport were proposed for the first time; 2) the methods of eliminating of energy overflows between sources are proposed; 3) the systems of dynamic reactive power compensation have been theoretically substantiated and implemented for the first time.

A series of the works contains the priority results in: providing theoretical substantiation of the phenomenon of instantaneous reactive power; influence of current pulsations on the selection of maximum power from the energy source; determination of stability areas for the joint operation of diesel generator and storage battery; distribution of the mechanical load on the moving transport axes, ensuring uninterruptable power supply of electric transport.

New control approaches for power supply systems consisting of a variety of different types of energy sources are offered.

The authors put forward new nonconventional tasks, namely: 1) for the first time in Ukraine,in the urbanelectric transport, a joint control system of three power sources(diesel generator, storage battery and central network)was used in the combined operation mode ensuring high efficiency of electric energy; 2) it is proposed to providedynamic compensation of electric energy in transition modes.

The results of a seriesare important for the design of distributed generation systems for the construction of electric transport systems and a centralized network, new methods for the formation and maintenance of trolleybuses with the possibility of their movement outside the power line at short and medium distances.
