Abstract
This paper comprehensively analyzes the far-reaching impact of electric vehicle charging on the grid load, and first Outlines the background of the booming development of the electric vehicle market and the accompanying boom in the construction of charging facilities. With the surge in the number of electric vehicles, their charging behavior has an increasingly significant impact on the grid load, including aggravating the peak and valley difference of the grid load, increasing load fluctuation and uncertainty, and possibly having a negative impact on power quality and grid stability. Aiming at these problems, this paper systematically discusses the management strategy of electric vehicle charging load. The orderly charging strategy is put forward to realize the distribution and balance of charging load by setting a reasonable charging time window, guiding user behavior and supplementing with incentive mechanism. At the same time, the importance of high-precision load forecasting is emphasized, and the prediction model is optimized with machine learning technology to provide strong support for power grid scheduling. In addition, this paper also discusses the intelligent scheduling scheme of charging piles, including cloud platform integration, network collaborative control and intelligent charging station design, in order to improve the utilization rate of charging facilities and the friendliness of the grid. Finally, this paper emphasizes the importance of promoting intelligent and orderly charging technology, and puts forward specific measures such as policy guidance, regulatory support, intelligent upgrading of charging infrastructure, and cross-departmental cooperation, in order to achieve harmonious coexistence between electric vehicles and the grid in the future. This study not only provides theoretical basis and practical guidance for EV charging load management, but also contributes to promoting energy structure transformation and sustainable development.
