The forthcoming surge in electric vehicle (EV) adoption demands the comprehensive advancement of associated charging infrastructure. In this study, an exploration of EV charging’s impact on the power distribution system is conducted via the simulation of a parking lot equipped with six distinct types of EVs, each showcasing unique charging curves, charging power, and battery capacities. A charging profile is synthesized and compared with laboratory-obtained data to ascertain the implications on the grid. To further understand the effects of smart parking on the power distribution system, a mathematical algorithm was created and applied to a segment of an urban electrical grid that includes 70 private residences. Basic electrical parameters were computed using the node voltage method. Four scenarios were simulated: (1) the existing distribution system, (2) the current system plus smart parking, (3) the current system plus 50% of houses equipped with 3.5 kW photovoltaic installations, and (4) the current system plus photovoltaics and smart parking. This paper examines the core distribution system parameters, namely voltage and current, across these four scenarios, and the simulation results are extensively detailed herein.

“…It follows that, based on (29), it is possible to determine the most suitable number of legs using the design and operation parameters of the converter in the buck mode so that the converter delivers the greatest possible power to the load under all operation conditions [21]. To validate that statement, the simulations, as well as experimental results are provided later in this paper.…”

The article describes the principles based on which it is possible to obtain energy from renewable sources more efficiently. The principles use the conventional DC-DC interleaved buck converter based on the common electronic component types and the control strategy. A novelty of such a proposed solution lies in the methods which are not new, but with the right combination, better results can be achieved. The resulting method can be implemented into various topologies where the highest efficiency for wide input power is required. In case of the renewable energy sources where the power can vary hugely during the day, the proposed method can be implemented. Therefore, the article provides several steps, from calculation through simulation to experimental results that brings reader close to understanding of a such proposed solution.

Purpose. The aim of the work is the design and creation of a modifiable closed-loop control system for DC to DC voltage regulation. Originality. The regulation parameters of modifiable close-loop control system can be easily change by proposed windows application. With such a system the regulation parameters can be easily determined without a calculation. Methodology. The paper as an example provides a description of a one DC to DC converter which belongs to buck-boost family. Presented converter is composed of two switching devices. For implemented a control strategy the galvanic isolated control signals technique was made to achieve desired control methodology. Control signals as well as the regulation itself was made by an ARM microcontroller type of STM32F103C8T6. Based on used MCU the control algorithm for voltage regulation was made. With such MCU the user interface where the whole system can be monitored and controlled was made also. The user interface is a windows application which was created with the help of a Visual Studio. Results. The paper provides the results achieved by the proposed control system. The results illustrated by windows application were compared with the oscillograms. From the results the incorrect regulation parameters can be easily spotted. Practical value. The advantage of such a control system is in the possibility of using it for various DC to DC converters where the regulation parameters can be easily determined without calculation. The user only connects the control signals to switching devices and connect the output voltage through voltage divider into the analogue input of the MCU. Disadvantage of the proposed system is, it can not be used without a PC where the windows application is running. Figures 15, references 8.
