Energy storages are indispensable in regard to the development of the smart grid with increasing fluctuating power generation. A valid choice of energy storages is important to ensure the efficiency of the system and selected application. This study describes an initial approach to model energy storage systems as an equivalent circuit. This model is capable of analyzing different load scenarios and...
This paper describes a graphical user interface (GUI) tool designed to support cell design and development of manufacturing processes for an automotive battery application. The GUI is built using the MATLAB environment and is able to load and analyze raw test data as its input. After data processing, a cell model is fitted to the experimental data using system identification techniques. The cell model's...
Carsharing has the potential to reduce the total number of cars on the road, with significant benefits to the society and the environment, while at the same time relevant studies show that university communities are often more receptive to alternative transportation services compared to the general population. With the growing interest in electromobility, as a means of decarbonizing the transportation...
Energy balance between electrical power demand and supply should be always under control for a safe mission. It varies with many factors. Simulation is an important study to consider these factors and to perform a reliable analysis of power subsystem. TUGES (TUSAŞ Uydu Güç ve Enerji Simülatörü) is a tool which is developed by TAI, based on MATLAB/Simulink software. It has been developed to have a...
In this work, the operation of a standalone streetlamp PV system is modeled considering actual outdoor operation conditions. The model integrates all components required in a stand-alone PV system: PV panel, battery, charge controller and load. Electrical characteristics of each component are based on those of a streetlamp PV system, currently tested in Singapore. Using measured irradiance data, the...
The battery is one of the most important components in electric vehicles. In this paper, a virtual battery model, which provides a framework of battery simulation for electric vehicles, is introduced. Using such a framework, we can model and simulate the performance of a battery during its usage, such as battery charge, discharge, and idle status, the impacts of internal and external temperature,...
The simulation is nowadays one of the most widespread instruments for analyzing the Wireless Sensor Networks (WSNs). Unfortunately, the most widespread WSN simulators today have only the basic model for the battery, which does not account many of the important real-life hardware dependences. Therefore in the paper we are suggesting a novel approach to modeling the energy consumption for battery-powered...
A Fortran program for analysing the energy balance in a satellite power system during Transfer Orbit and other mission phases is presented. Piece-wise integration is employed for computation of average battery current as the spacecraft spins, instead of calculus, to give full visibility of modelling techniques and provide data for plotting composite current and voltage waveforms. The program models...
