Abstract
In recent years, air pollution and climate change issues have pushed people worldwide to switch to using electric vehicles (EVs) instead of gas-driven vehicles. Unfortunately, most distribution system facilities are neither designed nor well prepared to accommodate these new types of loads, which are characterized by random and uncertain behavior. Therefore, this paper provides a comprehensive investigation of EVs’ effect on a realistic distribution system. It provides a technical evaluation and analysis of a real distribution system’s load and voltage drop in the presence of EVs under different charging strategies. In addition, this investigation presents a new methodology for managing EV loads under a dynamic response strategy in response to the distribution system’s critical hours. The proposed methodology is applied to a real distribution network, using the Monte Carlo method and the CYME program. Random driver behavior is taken into account in addition to various factors that affect EV load parameters. Overall, the results show that the distribution system is significantly affected by the addition of EV charging loads, which create a severe risk to feeder limits and voltage drop. However, a significant reduction in the impact of EVs can be achieved if a proper dynamic demand response programme is implemented. We hope that the outcomes of this investigation will provide decision-makers and planners with prior knowledge about the expected impact of using EVs and, consequently, enable them to take the proper actions needed to manage such load.
Highlights
Energy and transportation are the main sectors consuming fossil fuels [1,2]
The standard limit for voltage drop is approximately 7%, so the impact of 40% and 60% electrical vehicle charging (EVC) penetration levels is noticeable in the voltage drop of low voltage (LV) feeders
electric vehicles (EVs) on real distribution penetration level are significantly that they are veryinclose to the case
Summary
Found that the transportation sector consumes 53% of globally produced oil and accounts for 24% of direct CO2 emissions [3] For this reason, many governments are taking major measures to reduce reliance on fossil fuel combustion to fulfil their energy needs and to safeguard the environment. An unplanned increase in EVs’ penetration levels will lead to overloading the power lines and cables, transformer ageing, high voltage dips, increasing load losses in the power grid and degrading of power quality [11] For these reasons, investigating the effects of charging EVs through the distribution grid is of crucial importance in order to account for future expansion of the grid, as well as to take proper precautions for any unexpected events in the power grid. Analyzing the impact of EV charging on the power grid will enable authorities to enforce proper regulation strategies under the purpose of governing EVs’ charging behavior
