| Summary: | In the background of energy transformation, the world has witnessed the rapid development of new energy generation, with the proportion of capacity and electricity continuously increasing. However, different countries and regions have great differences in the access level of new energy. When a high proportion of new energy is connected to the system, it is neither scientific nor reasonable to reflect the development and absorption level of new energy only by such indicators as the proportion of new energy installed and the proportion of electricity generated. This paper analyzes the development status of new energy at home and abroad, and constructs the evaluation index system of the access level of new energy in power grid. Based on the evaluation index system, the access levels of new energy in different countries and regions are compared and analysed. At last, several key issues that need to be solved to achieve the goal of high proportion of new energy access in China are put forward.
