RBF Neural Network Based Virtual Synchronous Generator Control With Improved Frequency Stability

Fengjun Yao et al.

Summary: An adaptive control strategy for the virtual synchronous generator (VSG) based on the energy storage system is proposed to compensate for the loss of inertia and damping in the power grid, aiming to reduce power oscillation and improve response speed. The strategy utilizes a radial basis function NN to adaptively adjust virtual inertia, and tunes the damping coefficient based on a fixed damping ratio to suppress power oscillation. Simulation results demonstrate that the strategy performs well in damping oscillation.
