Adaptive Adjustment Method for Grid-forming Energy Storage Parameters Based on Buffer Functions and Damping Switching
摘要
Abstract
In the development tendency of high penetration of renewable energy and power electronic devices in new power systems,the grid-forming control technology for renewable energy integration mitigates the system stability issues caused by insufficient inertia and damping.However,it also reduces the dynamic regulation performance of the system.This paper proposes an adaptive adjustment method for grid-forming energy storage parameters based on buffer functions and steady-state/transient-state damping switching,to improve the dynamic regulation performance of the system.Firstly,the buffer functions are used in inertia adjustment to enhance the regulation smoothness of the system.Secondly,a steady-state/transient-state damping switching link is introduced in the damping adjustment to reduce the steady-state error of active power output during the frequency reduction process.Thirdly,the fuzzy control is employed to introduce correction terms for inertia and damping,and the stability of the proposed method is analyzed.Finally,simulations validate the effectiveness of the proposed method in enhancing small-signal stability and power response dynamic performance of the system.关键词
