Opis:
Purpose. To develop the fuzzy model of distribution of excess regenerative energy in traction and external power supply systems allowing to exercise effective operation of the power equipment. Relevance. For effective distribution of excess regenerative energy in systems of electric transport, as well as for systems equipped with stationary stores of energy and inverting traction substations with regulators of output voltage it is necessary to solve a number of the problems with high degree of uncertainty demanding taking into account a set of random factors such as the modes of power lines and traction loadings. These factors have to be considered in operation for choosing the rational modes of energy stores, inverters and regulators of voltage on buses of substations to provide the rational conditions for energy regeneration on electric transport. Scientific novelty. The control system of energy storage devices, inverters and traction substation output voltage regulators, designed on the basis of fuzzy logic, can provide the necessary conditions for the regeneration on electric transport on sections with a shortage of traction power consumption and allows to optimize the distribution of excess braking energy of transport vehicles. It is achieved by determining the rational relationship between the components of the excess current of regeneration in real time, which can ensure a minimum of power losses of regenerative energy in traction and external power supply systems. Practical importance. The use of the developed approach is effective under the conditions of incomplete information received by measurement systems and on the basis of additional studies it can allow to minimize rated capacity of stores, inverters and traction substation output voltage regulators that could reduce the costs of modernization of existing sections and electrification of new electric transport systems.

Opis:
Electrical vehicles have the ability to partially recover some kinetic energy during braking. Kinetic energy is transformed into electric energy, which is fed to the battery by the control system and stored there for further use. The aim of this paper was to analyse the levels of energy recovered by an electric vehicle during braking at various speeds and with different braking intensities. The first phase of testing consisted of vehicle braking tests in real-life conditions. The registered speed profiles were then used as input data for the simulation software. The authors have also analysed the effect of the state of charge of the battery and of the vehicle’s load on the amount of energy recovered during braking. The performed simulation tests demonstrated that the level of recovered energy is significantly affected by the initial braking speed and by the force of pressure applied to the brake pedal. The amount of recovered energy is less affected by the state of charge (SOC) of the battery and by the vehicle’s load. Energy regeneration during braking is currently an important research topic. The efficiency of an electric vehicle depends on the range, which can be extended thanks to the additional energy recovered during braking maneuvers. The presented preliminary simulation results are intended to assess the level of energy recovery in electric vehicles. The authors are aware that a full, comprehensive analysis requires additional research using electric vehicles that will verify the results presented in the paper.

Opis:
A well-known fact is that the world supplies of traditional fuel are decreasing and the world energy production from the alternative sources is constantly increasing. Each year the number of countries displaying a keen interest in development and application of regenerative energy is rising. Biomass is a considerable and perspective kind of fuel for Ukraine. Nowadays obtaining energy from biomass (wood, straw, plant remainders of agricultural production, manure, organic particle of hard domestic offcuts) is the field developing quickly and dynamically in many countries of the world. In favour of biomass speaks the fact that it has large power potential and refurbishable character. In our research we considered the use of straw for the receipt of energy and its practical value for a particular enterprise. As well as any type of power resource from biomass, burning of straw has a number of advantages. The advantage is that straw is indeed a regenerative source and is reproduced every year with the new harvest of grain crops. It is accessible for users, especially in rural locality that will allow saving part of facilities on traditional power carriers.

Opis:
Regenerative braking in electric or hybrid driven vehicles is now commonly used feature. Development of technologies of electrical machines, secondary energy sources, power electronics and control systems allows for more efficient using of this attribute. Regenerative braking system converts the kinetic energy of moving vehicles on this form of energy that you can store in a secondary source of energy. The most common form of energy after conversion is electricity, easy to store in batteries or supercapacitors. There also are known systems with storage of mechanical energy (high-speed flywheels with composite rotors). Drive systems with optional regenerative braking should take into account a number of aspects influencing the process. It is very important to maintain the stability of the vehicle movement during braking. Another important aspect is the cooperation of regenerative braking system with conventional, mechanical brake system of the vehicle driven by a single axis. Sizing of the electrical machine (or machines) is associated with the needs of the propulsion of the vehicle, which limits the amount of absorbed energy in the initial stage of braking. Individual elements of the system energy conversion efficiency chain complexity affect the energetic results of this process. On the energy, efficiency of the process of braking energy recovery affects string conversion efficiency in the individual components of the system. Regenerative braking is the important factor, which could improve electric vehicle market chances, particularly in the city or neighbourhood personal transport. The article contains a description of the technical and legal circumstances of the process of regenerative braking and energy aspects of this process.

Opis:
For city and neighbourhood people transport, electric driven vehicle with advanced energy storage and electronic control system could be competitive for conventional transportation means. Advanced energy storage and full utilization of regenerative braking system leads to significant energy saving. Regenerative braking is particularly important in city traffic, where a lot of acceleration/braking cycles occur. Replacement of internal combustion engines driven cars with electric vehicles give various benefits: decrease of transport sector impact on climate warming by CO2 emission reduction and general human health condition increase by elimination of toxic exhaust gases components emission by passenger cars. Particular interest of EV research is focused on lithium based batteries and supercapacitors. Nano-Lithium-Titanate battery could be fully recharged in a very short time and current peaks have no damage impact on the battery. Such batteries have high Cycle Life value (25000) and long life calendar (20 years).Fast charging systems should be equipped with energy converter built inside charging station. The converter has to be based on intelligent control system, for charging parameters setting (stable voltage, charging current, charging time) for different electric vehicles. To estimating charge/discharge characteristic and regenerative braking effectiveness, a simulation in MATLAB environment has been performed based on factory parameters. Graphical simulations results are presented in the paper.

W artykule przedstawiony został przegląd metod wykorzystania energii pochodzącej z hamowania odzyskowego. Wśród znanych i stosowanych w praktyce metod wymieniono wykorzystanie odzyskanej energii na nietrakcyjne potrzeby własne pojazdu, magazynowanie odzyskanej energii w zasobnikach (pokładowych lub stacjonarnych) i wykorzystywanie jej w razie potrzeby, transformację i zwrot odzyskanej energii do krajowej sieci zasilania, a także moż-liwość przesyłu odzyskiwanej energii z powrotem do sieci jezdnej i wykorzystanie jej przez inne pojazdy mające zapotrzebowanie na taką energię (np. w fazie rozruchu). Pokrótce omówiono zasady działania wymienionych metod, wskazano ich wady i zalety oraz podano przykłady zastosowania w praktyce. W podsumowaniu stwierdzono, że wskazane byłoby połączenie tych metod w zintegrowany system odzysku energii i zaproponowano ogólny schemat takiego systemu.
This article presents a review of methods for management of energy gained from regenerative braking. Among known and applied methods, the following are specified: using the recovered energy for non-traction own needs of the vehicle, storing the recovered energy in energy storage system (on-board or stationary) and its later use when needed, transformation and return of the recovered energy to the domestic power grid, and also the possibility of transferring the recovered energy to the traction network and its use by other vehicles (e.g., in during their acceleration phase). The principles of these methods are shortly described, their advantages and shortcomings are pointed out, and the practical applications are given. In summary, it is concluded that it would be advantageous to combine these methods into an integrated system of energy regeneration and a general scheme of such a system is proposed.

Opis:
The article refers to the previous work of the authors, in which the model of traffic organization of cooperating trains including the optimization of the use of energy returned to the catenary was presented. In the presented article, the model was modified by changing the main control variable, which affects the efficient use of energy. Departure time was changed for the arrival time of the train to the stop or station. The optimization is done by controlling the arrival time to the station in the acceptable (scheduled) range while maintaining the scheduled departure time. This model assumed optimization using the interval halving method (bisection) to achieve the optimal solution. The modified optimization method has been implemented in the original model of railway traffic organization. It considers the optimal use of energy recovered during electrodynamic braking using the energy transmission strategy to the catenary, assuming the cooperation of a train pair and volume of all recovered energy and stop time at the station.

Opis:
In a regular drive system, with an internal combustion engine, vehicle braking is connected with the unproductive dissipation of kinetic and potential energy accumulated in the mass of the vehicle into the environment. This energy can constitute up to 70% of the energy used to drive a vehicle under urban conditions. Its recovery and reuse is one of the basic advantages of hybrid and electric vehicles. Modern traffic management systems as well as navigation systems should take into account the possibility of the energy recovery in the process of regenerative braking. For this purpose, a model of a regenerative braking process may be helpful, which on the one hand will enable to provide information on how traffic conditions will affect the amount of energy dissipated (wasted) into the atmosphere, on the other hand will help to optimize the route of vehicles with regenerative braking systems. This work contains an analysis of the process of the regenerative braking for the urban traffic conditions registered in Gdańsk. A model was also presented that allows calculating the amount of energy available from the braking process depending on the proposed variables characterizing the vehicle traffic conditions.
