Electric power is the most widely used secondary energy in modern society, and the power industry is an important basic industry and public utility related to the national economy and people's livelihood. The safe, stable, and sufficient supply of electricity is an important guarantee for the national economy. With the development of the green, low-carbon, safe, and efficient power system, renewable energy power generation technologies such as wind and solar power have developed rapidly. However, as the scale of Chinese renewable energy power is continuously expanding, how to scientifically manage the large-scale renewable energy power grid integration quality is a major challenge. To cope with the new challenges of renewable energy development, it is necessary to establish a grid integration certification management system for Chinese renewable energy power, which is used to improve the quality of renewable energy power. It is basic work to solve the problem of renewable energy power grid integration.
