Abstract The paper describes the application of supercapacitor energy storage system for induction traction drive test bench that replaces a real electric public transport for performing testing and researches. The suitability and usage of such bench for research purposes is explained and the importance of the development of software mathematical model for performing simulations to be done before physical implementation measures is reasoned. The working principle of the bench and applied components are described. A virtual model of the bench was built and simulations were performed using Matlab/Simulink software. The basic topology of the virtual bench model is described as well. The calculations of this work show the scaling of supercapacitor energy storage system by setting different limits of working voltage range in order to adjust them to test bench parameters, whereas the modelling compares two simulation cases – the application of less supercapacitors and the application of more supercapacitors with the same common rated voltage. The autonomous mode simulations were also performed. Simulation results are analyzed and recommendations for the application of the supercapacitor energy storage system, with respect to initial supercapacitor circuit voltage, are given.

Objective: The development of hybrid technologies is an aspect that carries serious changes for the railway industry, its design and technological base. These changes provide the scientific and technological breakthroughs to a much greater extent than the implementation of any new projects in traditional forms. Methods: Of great interest is the solution to the problem of hybrid locomotives and related power supply interaction. In addition, there are problems of quality and reliability of the rolling stock. The relationship between the three sets of technology, as well as the problem of support quality of the latter, becomes essential for the successful implementation of hybrid locomotives with a combined power plant. Results: The primary problems of locomotive projects in question are: electric power storage, in-depth modernization of the traction drive, and implementation of an optimal motion control algorithms in different modes. Increasing energy density stored in the traction battery, while reducing vehicle mass, ensures competitive advantages of eco-friendly hybrid locomotives versus traditional. The cost of the traction battery tends to dominate over the relevant economic parameters of other components of the traction drive hybrid locomotives, therefore, projects with a high technological level are relevant, while ensuring lower total weight of the vehicle. However, in the last decade, due to the increasing importance of electronic components in the transportation industry, along with the objectives stated above, problems of management optimization of rolling stock systems and provision of an appropriate level of quality control take center stage. Issues of energy storage application in the hybrid locomotive and their advantages over the currently used energy sources are considered in the article. Practical importance: It is shown that the use of a hybrid energy storage system will significantly increase the efficiency and reliability of the locomotive.

<span lang="EN-GB">The paper is focused on the tram input LC traction filter stabilization by the Energy Storage System. The input LC filter is almost undamped resonant circuit which is mainly excited by the motor constant torque command. The tram during voltage drops increases the current flow from the LC filter to hold constant torque and thereby further decreases the LC filter voltage, and vice versa. This could lead to unstable traction drive behaviour. The Energy Storage System can be used to stabilize LC filter voltage.</span>

The limited capacity of renewable energy sources in the grid utility is a challenge. Increasing the capacity of renewable energy sources is supported by energy storage in the grid. The Battery Energy Storage System (BESS) allows storing more electricity from New and Renewable Energy (EBT) sources to meet load requirements. This paper designs a techno-economic study of various battery technologies using HOMER (Hybrid Optimization Modeling Software) software simulation. Simulations are made for grid-connected photovoltaic systems in Indonesia. HOMER is used to find the energy cost ($ / kWh) for each type of battery technology and battery system size. The simulation is designed using 1MWp PV component parameters, inverter, energy storage to be compared, residental load, and connected to the grid. The results will help to determine which technology and battery size is more suitable for the system. The findings from this paper resulted in the lowest Levelized Cost Of Energy (LCOE) of $ 1.03 in solar power generation.
