Abstract: Along with the development of the distributed resources technology and the increase of the distributed resources penetration on the grid, many international organizations and countries have promulgated and revised their own standards for interconnecting distributed resources with electric power systems. In order to explore the development trend of the Chinese and foreign standards for interconnecting distributed resources with electric power systems, and to learn the experience of formulating and revising the standards for interconnecting distributed resources with electric power systems, the international standards IEEE 1547 series of interconnection standards and Chinese standards for interconnecting distributed resources with electric power systems are mainly introduced in the paper, and the contents of response to abnormal conditions, power control, voltage regulation and the ability of low-voltage ride-through are compared. The standards for representative and rapidly developed wind power generation and photovoltaic power generation are concretely introduced. Through the vertical comparison of the original version and revised version of IEEE Std 1547, as well as the horizontal comparison of Chinese own different standards for grid-integration of distributed resources and foreign organizational and national standards, the cause of the difference between the standards is analyzed, and the development trend of the future standards for interconnecting distributed resources with electric power systems is discussed. The reference for the further improvement of the international standards and Chinese standards for grid-integration of distributed resources are provided. A foundation is also provided for the design of grid-integration inverter equipment and protection device.
