Smooth switching control method for grid-following and grid-forming converters

Journal of Physics: Conference Series
Abstract In the end grid with high penetration of new energy, a single control mode of grid-following or grid-forming makes it difficult to balance stability, economy, and grid-supporting capabilities. To solve the above problems, starting from the topological structures and mathematical models of grid-following and grid-forming ...
