Abstract

With the implementation of the green economy and the decarbonization strategy, the new energy automobile industry has developed rapidly in China, which poses new challenges to the balance and stability of the power system. This paper predicts the development trend of China's new energy vehicle industry through the random forest model, and analyses the impact of the development of new energy vehicles on power demand. The results show that the number of new energy vehicles in China is expected to increase significantly, accounting for a quarter of the total number of vehicles, and the number of charging piles will increase significantly to meet the demand. With the development of the new energy automobile industry, the demand for electricity and power load in the whole society are expected to maintain rapid growth, which poses new challenges to the power supply stability of the power grid. This study provides an important reference for government regulation, power grid adaptation and new energy vehicle enterprise development planning.
