As an important means of carbon reduction, the application scale of new energy power generation is gradually expanding. With the diversity of new energy access to grid, many wind or photovoltaic converters have directly encountered issues such as circulating current or resonance, so the operational characteristics and methods for new energy nearby connected converters are crucial for the safe and stable operation of enterprise power grids. Firstly, the current research achievements and main technical characteristics were introduced; Secondly, topology design and architecture are explained, then centralized complementary architecture principles are presented based on independent port constraints; Thirdly, energy release stability control based on active protection and system regulation strategy and constraints are studied. Finally, the conclusion summarizes the main research content, the line parameters in the application of nearby connected converters is the main performance influencing factors.
