A current limiting strategy for grid-forming converters based on voltage deviation adaptive virtual impedance

International Journal of Electrical Power & Energy Systems
Grid-forming (GFM) converters face the risk of saturation under large disturbances, which will degrade the stability performance of the system. Most existing adaptive virtual impedance methods generate virtual impedance based on current limit values ...

Power Equalization Strategy Based on Adaptive Virtual Impedance

Journal of Physics: Conference Series, 2023
Abstract Due to the differences in the line resistance of each distributed generation unit, conventional sag control does not allow for precise distribution of power, which also reduces the problem of system reactive power accuracy. To address this problem, this paper analyzes the power equalization and distribution conditions.
