China has developed a preliminary policy system for the development of new energy vehicles regarding the law, electricity price, grid-connected standards, project management, and financial support, however, defects remain in the policy and market environment, market mechanism, control technology, infrastructure, etc. We analyze new energy vehicles based on the analysis of basic data such as the number of electric vehicles and charging facilities, focusing on industrial development strategies, related subsidies, and tax policies. First, this paper summarizes the development status of China’s new energy vehicles in different scenarios. In 2021, China’s new energy vehicle production was 3545 thousand, and sales amounted to 3521 thousand. According to preliminary estimates, the number of new energy vehicles will exceed 15 million in 2030. The research route for the development of new energy vehicle bottlenecks is proposed. Secondly, we analyze foreign and Chinese policies on different stages and construct the implementation path for the healthy and stable development of China’s new energy vehicles. By comparing the basic indicators, related policies, and related innovation activities of new energy vehicles in China, we conclude that the development of the national electric vehicle industry needs to be increased in terms of government policies, business model innovation, and public awareness.

Building a new power system with new energy as the main body is an important means of achieving the goal of carbon neutrality. Compared with the traditional power system, the new power system has great changes and challenges in its safety mechanism and balance mechanism. Based on this, this paper focuses on the changes in the characteristics, functions and technologies of the new power system from the three sides of the source network and load. On this basis, the challenges faced by the high proportion of new-energy power systems are summarized from six aspects: reliability, stability, economy, data intelligence, flexibility and synergy. Finally, corresponding countermeasures, solutions and suggestions are put forward for the challenges of reliability, stability, economy, data intellectualization, flexibility and synergy, which provide ideas for the power guarantee of the new power system.
