Research on Evaluation Method of New Power System Industry Chain Autonomy Level

Currently, the global energy transformation is accelerating, and China's new energy security strategy is being advanced. The international competition in the power industry and related technologies is becoming increasingly prominent. The autonomy of core technologies is an inevitable choice to ensure national energy security and construct new power system. In this paper, the disadvantages of industry comprehensive analysis, simple calculation methods, low accuracy are considered. The comprehensive autonomy level assessment indices for the new power system industry chain autonomy level are constructed, which helps to accurately judge the foundation of the power industry chain and key equipment. It provides a scientific reference for the implementation of scientific and technological research on new power systems and to accelerate the realization of a high level of autonomy.
