Study and Comparison on Standard for Interconnecting Distributed Resources with Electric Power Systems

This paper introduces the domestic and foreign standards for interconnecting distributed resources with electric power systems, and compares the contents of power quality, response to abnormal conditions, power control, voltage regulation and the ability of fault ride-through in some typical standards. Some items in wind power generation and photovoltaic power generation standards are concretely introduced. 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. This paper provides reference for the further improvement of the standards for grid-integration of distributed resources.
