When electrical energy is drawn by electric vehicles from charging stations at charging process the voltage drops and increased current loading of cable lines in distribution grid occur. Inasmuch the electrical grid is insufficiently dimensioned or at large amount electric vehicles concurrently charges without controlled charging system, the voltages could decrease under desired level in grid points. This leads to the deterioration of voltage quality in given grid. The higher cables current loading leads to active power losses increase and decrease their service life. The paper describes the utilisation of modelling the electric vehicles when charging by power load model in physical diagram implemented into alternative simulation software. The created charging station load model is used for solving of voltage studies in distribution grid and for the analysis of cable lines ampacity. The grid contains a small number of points and low penetration of charging stations. Voltage levels are solved when random operation of charging stations during the working day without controlled system. For other loads, the typified daily loads diagrams of households are used.

“…An analysis has been conducted to highlight EVs as a clean energy alternative compared to vehicles using gas and fossil fuels. The study extensively examines how non-linear loads affect the power quality of EVs [6]. Das et al (2019) have explored the current state of the EV market, standards, charging infrastructure, and the impact of EV charging on the grid in their study [7].…”

Today, due to environmental concerns and limited energy resources, electric vehicles are rapidly becoming popular. Therefore, developments in battery technologies and charging stations are an important factor for these vehicles to become more widespread. Increasing the number of stations offering fast charging will increase the number of electric vehicle owners or rental companies and enable more comfortable travel. Additionally, the use of energy obtained from Renewable Energy Sources (RES) will ensure that charging stations are environmentally friendly. In this study, technical and economic analysis of a small-scale RES and storage Electric Scooters (ES) charging station modeling was conducted at Marmara University Recep Tayyip Erdogan Complex (MURTEC) to support student intra-campus transportation. In the study, modeling was done with different Hybrid Power System (HPS) configurations, RES, and equipment manufacturers using Homer Pro software. Designs are optimized to find the system that performs best in each scenario. A comparative analysis was carried out between different systems in terms of carbon emissions and cost savings, among other parameters.

“…by coordinating the PV, ESS, and charging with the AC grid by controlling the frequency, thus reducing the battery size (24). With AC grid-connected charging stations the poor power quality and large total harmonic distortion (THD) are issues (25). When connected with the AC grid, peak load demand must be considered and close coordination between PV, ESS, and EV charging will result in increased overall efficiency, by improved electricity infrastructure utilization (26).…”

There is a drift in automotive industry from conventional internal combustion engines (ICE) to Electric Vehicles (EVs). This drift from ICE to EVs counts to the reduced carbon emission and thus reducing environmental pollution. EVs also find a solution for increasing fossil fuel costs. When it comes to renewable energy sources, typically to solar energy, it is affluent and reliable. The usefulness of solar energy is maximized by the incorporation of advanced power converter topologies along with their advanced controls. This paper aims to compare some of the boost converter topologies that are used in EV applications with solar photovoltaic powered charging stations. The comparative study is conducted on various parameters, such as DC voltage gain, duty-cycle, efficiency, voltage stress, merits, and demerits. Simulation results are analyzed and compared using MATLAB/Simulink platform.
