基于3种SOGI-GD-FLL算法的储能变换器虚拟惯量设计与评估
Virtual Inertia Design and Evaluation of Energy Storage Converter Based on Three SOGI-GD-FLL Algorithms
摘要
Abstract
Among the existing virtual inertia control methods for energy storage converters(ESCs)based on the grid frequency differential signal(GFDS)detection,the second-order generalized integrator-frequency locked loop(SOGI-FLL)on the basisi of the gradient descent(GD)(abbreviated as SOGI-GD-FLL)algorithm has become one of the key technologies due to its effective extraction of GFDS.However,systematic evaluation of different GFDS detection methods under the GD algorithm and their virtual inertia control performance is still insufficient.Therefore,two GFDS detection algorithms different from the typical SOGI-GD-FLL control structure are proposed.Firstly,the control loops for two GFDS detection algorithms by reconfiguring the mathematical relationship of their output signals are constructed.Then,the small-signal mathematical models and parameter design methods for all three algorithms are simultaneously present.Finally,the MATLAB/Simulink simulation and experimental comparison results verify that the three SOGI-GD-FLL algorithms can accurately detect GFDS and provide reliable input for the virtual inertia control of ESC.关键词
