Abstract
In the global energy transition, large-scale integration of new energy into the grid has become an inevitable trend. High-frequency power electronic converters, as key interfaces, excel in power conversion, transmission, and grid regulation. By operating at high frequencies, they enhance the accuracy of power conversion and efficiently adapt to the intermittent output of new energy sources such as photovoltaic and wind power. Not only do they reduce harmonics and optimize power factor, ensuring power quality, but they also flexibly adjust power output, enhancing grid stability. This provides solid support for the reliable and efficient integration of new energy into the grid, contributing to the development of a sustainable energy system.
Key words： High frequency power electronic converter; New energy grid connection; Power quality; Power regulation; Power grid stability
