“…Many authors have dealt with the influence of EV charging processes on the distribution grids, mainly with the voltage deviations. They have used for the voltage studies especially commercial softwares as Neplan [2,6] DlgSI-LENT [4] or MATLAB-Simulink [14][15][16].…”

“…Consumed currents reach level of several tens of amperes, leading to influence the grid operation. The voltage deviations occur especially which can reach an undesirable level leading to deterioration the voltage quality parameters [1][2][3][4][5][6][7][8][9][10]. The voltage unbalance arises in non-symmetrically loaded grids and also during the unbalanced charging process of EVs [1,3,7].…”

“…The voltage unbalance arises in non-symmetrically loaded grids and also during the unbalanced charging process of EVs [1,3,7]. At significant current or active power grid loading the level of active power losses also increases [1,2,[5][6][7][8], consequently leading to the decreasing of electrical devices service life [1,2,5,7]. The most affected devices are transformers and cable lines.…”

“…Analogical issue solve authors for the larger distribution grid containing several radial lines, where each contains approximately 100 loads in [3], for the 33-nodes IEEE grid in [5], and for the large area city distribution grid in [4]. Authors in [2] deal with the active power demand which directly corresponds to the active power losses level in grid. In a paper [5], authors solve increased active power demand caused by installed given types and number of EVCSs, active power losses and economic losses.…”

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.

Summary This research paper proposes a detailed design problem of electrical vehicle (EV) fast‐charging stations to maximize the net profit. The charging station is integrated with the renewable energy sources (RES) and battery energy storage system (BESS) to minimize the energy demand from the grid. The performance indices of the design problem, such as the number of chargers and their rating, installed RES power, energy and power of the storage units, and dynamic power contracted by the grid to the EV charging station, is estimated through the proposed algorithm. The detailed modelling of the charging process considers the EV behavioural characteristics like arrival time, state of charge, departure time, and battery capacity and is simulated through sequential Monte‐Carlo method. The hybrid Crow Search Algorithm (hCSA), along with the particle swarm optimization (hCSA‐PSO), is adopted for the first time to optimize the charging station's installation and operational cost. The effectiveness of the proposed method is compared with a hybrid genetic pattern search algorithm, CSA, and PSO. Several case studies are considered, and it is observed that hCSA‐PSO provides the best‐optimized results in profit maximization. The cost‐benefit analysis is also performed to estimate the financial feasibility of both RES and BESS.
