The analysis of the development and implementation of environmentally friendly electrical technologies in the transport industry and the analysis of existing projects for the conversion of conventional diesel buses into trolley buses and electric buses. The technological solutions that contribute to the spread of electric transport in large cities and megalopolises are given. Researching the model of electric propulsion system for buses with the Matlab Simulink programming environment was carried out to obtain the main characteristics of the flow of electrical and electromechanical processes in the equipment. The paper presents modeling the work proposed electric propulsion system of an electric bus for urban use. During the simulation, the principle of vector control of asynchronous motors (AM) as part of the electric propulsion system of the electric bus was implemented. The results of such a simulation allow us to eliminate errors and inaccuracies in the design of the control system of the AM and to debug the control algorithms in different operation modes of the control system. The mechanical characteristics of the AM traction, while operating in the electric power drive of the electric propulsion system for buses were built.

There are a lot of possibilities to control devices remotely nowadays. Doing this with brain waves is not a science fiction anymore. The first steps for device control by brain are already made. The main challenge is identification and classification of the human waves corresponding to the movement, emotions and so on. Brain-Computer Interfaces (BCI) devices provide a connection between the user's brain and the computer. These can be observed in our daily life, such as Medical Applications, Neuroergonomics and Smart Environment, Neuromarketing and Advertising, Education and Self-Regulation, Games and Entertainment, Security and Authentication, etc. To reach the best result a reliable classification of BCI signals is needed. Controlling machines and making science fiction with the power of our mind is a reality today. This study deals with increasing accuracy of the processing and classification of the Brain Wave Signals. This approach is based on pre-determination of the channels with useful information and consequently precise classification of the signals. In this experiment, the BCI device Emotiv 14-Epoc is used for collecting brain signals. They are received from BCI devices. The signals classified are based on the Mixed Linear Programming (MLP). This is an approximation to reach the goal- precise identification of brain signals. The results indicate the necessity of approaches that enhance the characteristics: capabilities and quality. The main results of the presented work show the accuracy of signals identification is improved from 60% to 90% when preliminary determination of the channels is done.

Nearly Zero Energy Buildings (NZEBs) in the building sector, one of the most energy intensive fields in the modern world, are facing new challenges. These extremely energy efficient buildings can produce their own energy whereas local storage and sources are needed. To meet those goals, new technologies and control principles must be developed and implemented. Energy usage could be best optimized by a central energy management system (EMS). This paper proposes an energy router-based EMS for NZEBs. The concept and its features will be explained and analyzed. The energy router has many tasks, e.g. energy routing, system protection and reliability, voltage regulation. However, the focus of this paper will be on the power quality at the point of common coupling (PCC). Modern households are overwhelmed by the nonlinear electrical loads, which are lowering the power quality in the grid. The power quality is a serious issue also in NZEB. This paper will demonstrate how an energy router can be used to control reactive and active power and compensate current harmonics at the PCC. The system behavior will be simulated and verified by the experimental prototype.

The main objective of the transport operations is a safe transportation process. There are various methods for gaining this task. This paper is a part of a big research, aimed at the developed of autonomous electric drive, and discusses one of the aims of the research - collision probability calculation of transport vehicles team moving in the one area. The goal of the current research is to develop a computer model, which would help to detect the possible crossing point of transport vehicles team parties, moving in one area, and calculate the collision probability. This information can be used further for the collision probability minimization by use of the appropriate actions. Previously authors have developed and described algorithms for collision probability minimization tasks. Proposed algorithm was implemented in the computer model. Computer simulations prove the workability and advantages of the developed model.

Today, dedicated metal 3D printing platforms can produce industrial grade homo-material metal components, promoting the fabrication of soft magnetic components for electrical machines with three-dimensionally optimized topologies. The printed components have been shown to exhibit excellent DC magnetic properties, indicating the maturity of the technology for applications incorporating quasi-static magnetic fields, such as magnetic couplings or rotors of synchronous machines. In the paper, finite element modeling of a synchronous reluctance magnetic coupling is investigated. Previously 3D printed and researched material of electrical steel with 6.5% added silicon content with selective laser melting is adopted in the model, alongside the printing limitations of the printing system. Commercial finite element modeling software COMSOL Multiphysics is employed for modeling. Printing of the modeled coupling was currently unsuccessful due to unoptimized printing parameters.

The results of the study of the influence of active power produced by solar power plants (SPP) on voltage 0.4 kV tires of consumers are presented. It is proved that in local electrical systems: there are possible modes when the voltage on the 0.4 kV bus of consumers can be outside the normalized values; almost without limiting the generation of active power SEP and regulating reactive power SPP is the ability to regulate the voltage on 0.4 kV tires consumers, to prevent excess normalized voltage deviations. This will reduce the use of voltage transformers and switching devices for static capacitors.

Due to new requirements in the market relations for regulation of power in the energy system, the issue of balancing is becoming more and more important. In European countries, the regulation of the power system is made by the system operator, but it is carried out by private companies who have own generation units to provide certain reserve capacity for each hour. There is certain disagreement over which particular methods should be used in terms of optimal generating equipment maintenance planning and how to do that without financial losses. The purpose of the research is to analyse the effectiveness of the directed search method and its possible modifications, and to estimate the behaviour of the power system relative power reserve within a maintenance period which could be of paramount importance for closely related generation adequacy investigations.

This paper presents the stages of developing a power supply system for a probe placed in the stomach of a cow. The power supply system is based on Triboelectric affect. To evaluate the operation, a triboelectric nano generator was built. The triboelectric nano generator has been tested in three different ways. Work at low frequency, work at high frequency and work at high frequency with a connected energy storage. At the next stage, it was necessary to conduct motion tests to obtain information about the mechanical energy produced by a cow or other individual. To do this, a measuring device was built and tested, tests included measuring the duration of work in a wide temperature range and under strong mechanical stresses, were carried out for six weeks. To obtain vibration data, the device was mounted on the human body. Data was taken during the day. The measured data were used for the average energy produced by a person's movement during the day. As a result, it was stated that in order to obtain the necessary power for supplying the probe, it is necessary to produce a triboelectric nano generator with a total surface area of 2.5 [sq. m.]. Which is realistic using nanostructures.
