The impact of new energy vehicles on the electricity load is mainly in the following aspects:
Increase the peak load of the power grid: The disorderly charging of new energy vehicles will lead to fluctuations in the load of the power grid, causing fluctuations in the power system during peak power consumption periods, and negatively affecting power generation equipment and power quality. Exacerbating the peak-to-valley difference of load: Due to the increasing charging capacity of new energy vehicles, the peak-to-valley difference of the power grid is further expanded, which has an adverse impact on the stable operation of the power system and the power quality. Local overload problem: With the continuous increase of on-board battery capacity, the charging load of single vehicles continues to increase, which may lead to overload of the power grid in local areas and affect the quality of the distribution network. Impact on the distribution network: The charging volume of new energy vehicles is increasing year by year, and the proportion of electricity consumption in the whole society is also increasing. It is expected that by 2030, its proportion will reach 46%, which puts forward higher requirements for the power supply quality and stability of the distribution network. Therefore, it is necessary to take effective measures to guide and regulate the charging behavior of new energy vehicles to reduce their impact on the power grid load. For example, new energy vehicles can be encouraged to charge during off-peak hours by formulating a reasonable charging strategyAt the same time, the construction and transformation of the power grid will be strengthened to improve its carrying capacity and stability.
