Abstract

In this research, a decentralized voltage control approach has been proposed as a crucial process in managing future fast electric vehicle charging stations. Voltage control is critical for maintaining system efficiency and safety, utilizing both droop control principles and fine-tuning to respond to voltage drops in the distribution system concerning power flow into the charging station. This process involves steps such as measuring the desired voltage for control, then using droop control techniques to adjust the voltage at connection points. This droop control relies on the relationship between voltage and reactive power, employing adaptive techniques to ensure electric vehicle fast charging station maintains voltage within safe limits. This is crucial for system efficiency. Subsequently, the cost-benefit of compensating reactive power for the distribution system over a 10-year simulation period will be evaluated using Cost-Benefit Analysis. The simulation will employ a 14-BUS network and a real distribution system model of the Chiang Mai 1 feeder 1. Test results indicate that managing reactive power compensation for fast charging stations in the distribution system, based on droop control methods, effectively regulates the reactive power of the charging station to respond to voltage control at connection points, meeting the grid connection requirements. Additionally, it aids in mitigating the investment impact of upgrading the distribution system to reduce the impact of electric vehicle charging stations.
