Adaptive control strategy for grid-based energy storage converter under frequency disturbance

Abstract

The grid-based energy storage converter is regarded as vital equipment for constructing a new power system because of its ability to sort out new energy consumption and improve the system’s moment of inertia. Currently, most of the adaptive control strategies of Grid-configured energy storage are optimized for the dynamic virtual synchronous generator technology (VSG) process. More research is needed on the steady-state deviation of VSG under grid frequency disturbance. To solve this problem, this paper proposes an adaptive control strategy for grid-based energy storage converters. First, this essay examines the control approach used by VSG. Subsequently, the damping and inertia of VSG with fixed parameters are replaced by the inertia, and damping is calculated using the adaptive algorithm to optimize the dynamic and steady-state performance. Finally, Simulations utilizing MATLAB/Simulink are employed to confirm the efficacy of the adaptive VSG network-building control approach.
