Evaluating the possible impact on power system of a large number of electric vehicles (EVs) is becoming of great interest. With the development of V2G technology, electric vehicles constitute a significant power reserve. In addition, batteries in electric vehicles may be used to provide storage capability for energy produced by renewable sources and to supply auxiliary services to the grid. The paper presents the preliminary results of an on-going project aimed at evaluating the impact of electric vehicles on power system. The simulation results shows significant benefits of V2G on the daily load profiles and network planning. Hypotheses such as battery size, number of users, load profiles without and with different EV penetration are presented for successive scenarios set-up and simulations.

The Impact

With the popularization and application of electric vehicles, charging and discharging load will bring new challenges to safe and stable operation of the power grids. Charging and discharging control is becoming an important power system operation strategy as well as generation dispatch. A volume of research has been devoted to charging control (including vehicle-to-grid, so-called V2G) which can not only alleviate the adverse effects of charging load but also support the grid operation such as leveling the load and promoting the integration of renewable generation. This paper analyzes the impact of electric vehicles charging and discharging on the power system.

The Impact

During the last few decades, electric vehicles (EVs) have emerged as a promising sustainable alternative to traditional fuel cars. The work presented here is carried out in the context of the Horizon 2020 project MERLON and targets the impact of EVs on electrical grid load profiles, while considering both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) operation modes. Three different charging policies are considered: the uncontrolled charging, which acts as a reference scenario, and two strategies that fall under the umbrella of individual charging policies based on price incentive strategies. Electricity prices along with the EV user preferences are taken into account for both charging (G2V) and discharging (V2G) operations, allowing for more realistic scenarios to be considered.

The Relationship

Electric vehicles (EVs) are developing remarkably fast these years which makes the technology of vehicle-to-grid (V2G) easier to implement. Peak load shifting (PLS) is an important part of V2G service. A model of EVs’ capacity in V2G service is proposed for the research on PLS in this paper. The capacity is valued in accordance with three types of situations. Based on the model, three different scenarios are suggested in order to evaluate the capacity with MATLAB. The evaluation results indicate that EVs can provide potential energy to participate in PLS. Then, the principle of PLS with EVs is researched through the analysis of the relationship between their power and capacity. The performance of EVs in PLS is also simulated. The comparison of two simulation results shows that EVs can fulfill the request of PLS without intensely lowering their capacity level.

The Mathematical Model

TA mathematical model describing heat and mass transfer performance of packed-type parallel flow dehumidifier was set up. The numerical solution of differential equations was derived. Taking the heat and mass transfer coefficients obtained by experiments as the input parameters of the model, the impact of solution inlet parameters on outlet parameter of air was described. The simulation results indicated that the mathematical model could be used to predict the performance of liquid dehumidification. The results showed that the mathematical model can be of great value in the design and improvement of dehumidifier.

Abstract The following paper focuses on the electric vehicles sector development and its possible influence on power system load in Poland. The goal is to estimate the increase of power demand resulting from the electric cars charging. First of all, the current legal environment, which provides a framework for the e-mobility sector evolution, was described. Furthermore, the technical process of electric vehicles charging was depicted and the applicable methods of cooperation between e-mobility and power system were proposed. The quantitative analysis of the impact of the electric vehicles charging on the power demand in the National Power System was conducted. The input data and adopted assumption were specified. The structure of the calculation model and the differences between analyzed scenarios were described. The outcome obtained for the National Power System and Warsaw distribution area were presented.
