Abstract: To build a new electric power system, it is necessary to solve the impact of new energy power stations on the stability of power systems, and improve the grid-source coordination performance of new energy sources.Based on the on-site grid-related test data, the test results of power quality, active and reactive power control performance, SVG performance, fault traversal performance and grid adaptability of the new energy power station are statistically analyzed.It is pointed out that the testing project of fault traversal performance and adaptability of power grid is the weak point of the current coordination and management of network sources of new energy field stations, and it should be the key work in the future.The typical problems of fault traversal and network adaptability are summarized and analyzed, and the corresponding countermeasures are put forward from the managerial and technical levels to support the transformation and development of power system.

Key words: grid source coordination, new energy, grid source test, fault crossing
